This study investigated teacher perceptions of school resource officers (SROs) and their associations with school safety. The sample consisted of 10,668 teachers in 404 middle schools and 11,900 teachers in 284 high schools. Most middle (86.5%) and high (85.5%) school teachers agreed that the SRO makes them feel safer; however, endorsement differed by race, gender, and teaching experience. Regression analyses found favorable teacher perceptions of their SRO were associated with a greater feeling of safety and security, higher job commitment, and lower teacher victimization. Although correlational, these results add a missing teacher perspective that should be considered in policy debates over the role of SROs in schools.

National interest in using school climate as an accountability measure makes it important to understand how school leaders view and make use of school climate data. The purpose of this study was to investigate how school and district administrators use climate data in Virginia, where a statewide school climate survey is annually administered. School principals (N = 283) completed surveys concerning their use of the school climate results for their school. Simultaneously, semi-structured interviews were conducted with school division leaders and school administrators (N = 10) to deepen our understanding of how the school climate results were being used. Qualitative content analysis was used to identify patterns in the data. Study results reflect a consensus by educational leaders on the utility of receiving school climate data in order to make data-based decisions to improve outcomes for students. Participants provided thoughtful and constructive feedback on the importance of student relationships, perceptions of student subgroups, comparing their data with other schools, and ways to facilitate data-based decision-making. Participants also expressed a desire for additional support in understanding statistical results and generating recommendations for school improvement. These findings suggest that increasing the clarity and comprehensiveness of school climate data reports and providing support for interpreting the results will increase educational leaders' ability to use school climate surveys.

National debate over law enforcement in schools has largely overlooked student reporting of violent threats to school resource officer (SROs). This statewide assessment of Virginia high school students (n = 99,358) found that the majority of Black (64%), Hispanic (72%), White (71%), and other racial/ethnic identity (71%) students agreed the SRO made them feel safer at school. Logistic regressions revealed that positive perceptions of the SRO and frequency of speaking with the SRO were associated with increased willingness to report a peer who brought a gun to school or talked about killing someone. Perceptions of the SRO interacted with student race/ethnicity such that favorable views reduced disparities in nonwhite students' willingness to report a peer with a gun. Although correlational, these results suggest that positive relationships with SROs encourage students to report threats of peer violence.

This study tested the authoritative school climate theory that schools characterized by high structure and student support have greater levels of student engagement and that these factors are associated with higher academic achievement, as indicated by school graduation rates and school performance on state-mandated testing. The model was tested through a multilevel multi-informant structural model on a statewide sample of 60,441 students and 11,442 teachers in 298 high schools. Consistent with the authoritative school climate model, both structure and student support were associated with higher student engagement in schools. Moreover, student engagement was directly associated with academic achievement and operated as an intervening factor. Results provide new evidence that an authoritative school climate is associated with high school academic achievement.

This study evaluated the longitudinal psychometric properties of the Authoritative School Climate Survey (ASCS) using a statewide sample of middle and high schools across 8 years. Multilevel confirmatory factor analyses were conducted to test the longitudinal measurement invariance of three scales on the ASCS: disciplinary structure, teacher respect for students, and students' willingness to seek help. These scales demonstrated strong factorial invariance across all time points for both middle and high schools. Results support the use of these scales in evaluating longitudinal change in school climate.

Zero tolerance as an approach to school safety has been around for almost 3 decades. Despite widespread criticisms of zero tolerance policies, few empirical studies have investigated the relationship of zero tolerance with school safety. More generally, the Government Accountability Office report on school shootings noted the need for research on the link between school discipline and school safety. Using a statewide survey from 108,888 students and 10,990 teachers from almost all Virginia middle schools, we found that a majority of surveyed teachers (74%) supported the use of zero tolerance as an effective discipline practice. Analysis using both linear and logistic regression indicated that support for zero tolerance was associated with higher rates of out-of-school suspension. Contrary to the goals of zero tolerance, both students and teachers in schools with greater support for zero tolerance had lower feelings of safety at school, even after controlling for school and student characteristics associated with safety. These findings offer new evidence to support efforts by school psychologists to discourage the use of zero tolerance and promote more effective school discipline practices.

This study tested the theory that an authoritative school climate characterized by disciplinary structure and student support is conducive to positive academic outcomes for middle and high school students. Multilevel multivariate modeling at student and school levels was conducted using school surveys completed by statewide samples of 39,364 students in Grades 7 and 8 in 423 middle schools and 48,027 students in Grades 9 through 12 in 323 high schools. Consistent with authoritative school climate theory, both higher disciplinary structure and student support were associated with higher student engagement in school, higher course grades, and higher educational aspirations at the student level in both samples. At the school level, higher disciplinary structure was associated with higher engagement, and higher student support was associated with higher engagement and grades in both samples. Overall, these findings add new evidence that an authoritative school climate is conducive to student academic success in middle and high schools.

Educators and researchers have long debated the best grade configuration grouping for middle grade students. This study examined school-level differences in reading and mathematics standardized test pass rates for students placed in middle schools versus alternative grade configurations. Latent growth modeling was conducted separately for 6th, 7th, and 8th grades across a 3-year sampling period. Sixth-grade pass rates were significantly higher in elementary schools (e.g., Kindergarten-7th grade) than in middle schools for reading (78.9% vs. 72.0%) and mathematics (82.5% vs. 76.3%). Seventh-grade pass rates in elementary schools were also significantly higher than in middle schools for reading (78.5% vs. 75.9%) and mathematics (83.1% vs. 69.2%). Eighth-grade pass rates were significantly higher in middle schools than in high schools (e.g., 8th-12th grade) for both subjects (74.7% vs. 70.0% for reading, 63.3% vs. 52.0% for mathematics). These findings suggest that students benefit from remaining in elementary school through at least 7th grade.

Virginia law mandates the use of threat assessment in all public schools, yet there is little research on grade-level differences. This study investigated a statewide sample of 3,282 threats from 1,021 schools. Threats significantly differed across grade level in demographics, characteristics, and outcome. As grade increased, students were more likely to threaten physical assaults (OR = 1.11, p < 0.001), but less likely to threaten with weapons (OR = 0.95, p < 0.01). Notably, 1st graders (OR = 2.01, p < 0.05) were two times more likely to threaten to kill, but 9th graders were more likely to attempt their threats (OR = 1.02, p < 0.05). These findings highlight the need to consider grade level in evaluating and responding to student threats of violence.

Threat assessment has been proposed as a method for schools to respond to student threats of violence that does not rely on exclusionary discipline practices (e.g., suspension, transfer, expulsion, arrest). The present study compared disciplinary consequences for 657 students in 260 schools using the Comprehensive Student Threat Assessment Guidelines (CSTAG) with a comparison group of 661 students in 267 schools using a more general threat assessment approach. The odds that students receiving a threat assessment in CSTAG schools would receive a suspension (OR = 0.59) or law enforcement action (OR = 0.47) were less than those in schools using a general approach. Students in CSTAG schools were expelled at lower rates (0% versus 1.7%) than students in comparison schools. These results indicate that schools using the CSTAG model are less likely to respond to student threats with exclusionary discipline.

School sexual harassment (SH) is defined as unwelcome behavior of a sexual nature that interferes with a student's ability to learn. There is an important need for schools to assess the prevalence of SH and its relation to school climate to guide intervention efforts. This study investigated 3 research questions: (a) Is there psychometric support for a 4-item multilevel measure of SH? (b) What is the prevalence of SH in a statewide high school sample, and how does SH vary across gender, grade level, race-ethnicity, and socioeconomic status? (c) Is an authoritative school climate--characterized by strict but fair discipline and supportive teacher-student relationships--associated with lower levels of SH for students? A statewide sample of high school students (N = 62,679) completed a school climate survey that included a new 4-item measure of SH. Results of a multilevel confirmatory factor analysis indicated good fit for a single SH factor at both student and school levels. A multiway analysis of variance demonstrated the high prevalence of SH and variations across demographic groups. Multilevel hierarchical regression analyses indicated that an authoritative school climate accounted for 5.7% of the student-level variance and 38.3% of the school-level variance in SH scores. Routine assessment of SH can help school psychologists bring attention to this underrecognized problem.

Threat assessment is a violence prevention strategy used to investigate and respond to threats to harm others. In 2013, Virginia mandated the use of threat assessment teams for threats to self and to others, effectively subsuming suicide assessment with threat assessment and raising questions about the distinction between the two practices. In a statewide sample of 2,861 cases from 926 schools, there were more threats to self (60%) than others (35%), with only 5% involving threats to both self and others. Threats to self were more likely to be made by females (odds ratio [OR] = 3.38) and students with fewer prior disciplinary actions (OR = 0.48). Threats to self were much less likely to involve a weapon (OR = 0.07), but more likely to be attempted (OR = 1.50) and result in mental health services (OR = 2.96). They were much less likely to result in out-of-school suspensions (OR = 0.07), legal action (OR = 0.17), and/or changes in placement (OR = 0.53). Overall, these findings support a clear distinction between suicide and threat assessment.

In response to media reports of increased teasing and bullying in schools following the 2016 U.S. presidential election, we investigated its prevalence with a Virginia school climate survey completed by approximately 155,000 seventh- and eighth-grade students in 2013, 2015, and 2017. Survey results were mapped onto presidential election results for each school division's locality. In localities favoring the Republican candidate, there were higher adjusted rates of students reporting that (a) they had experienced some form of bullying in the past year (18% higher) and (b) "students in this school are teased or put down because of their race or ethnicity" (9% higher). For these two outcomes, there were no meaningful differences prior to the election. These results provide modest support for educator concerns about increased teasing and bullying since the 2016 presidential election in some schools and warrant further investigation.

In 2013, VA became the first state to mandate the use of threat assessment teams in its K-12 public schools. We provide an account of the development and adaptation of threat assessment as a school safety practice and research on the Virginia Student Threat Assessment Guidelines in VA schools. We describe the state law and the question of whether suicide assessment should be considered a form of threat assessment. We then describe research on the statewide implementation of threat assessment and summarize results indicating overall positive outcomes for schools who are actively engaged in threat assessment, but qualitative findings from a needs assessment identified team training gaps as well as a need to orient the larger school community to the threat assessment process. We describe a series of online programs to educate students, parents, teachers, and other school staff about the threat assessment process. In conclusion, this paper presents some lessons learned in the statewide implementation of threat assessment as a safe and effective violence prevention strategy.

Threat assessment has been widely endorsed as a school safety practice, but there is little research on its implementation. In 2013, Virginia became the first state to mandate student threat assessment in its public schools. The purpose of this study was to examine the statewide implementation of threat assessment and to identify how threat assessment teams distinguish serious from nonserious threats. The sample consisted of 1,865 threat assessment cases reported by 785 elementary, middle, and high schools. Students ranged from pre-K to Grade 12, including 74.4% male, 34.6% receiving special education services, 51.2% White, 30.2% Black, 6.8% Hispanic, and 2.7% Asian. Survey data were collected from school-based teams to measure student demographics, threat characteristics, and assessment results. Logistic regression indicated that threat assessment teams were more likely to identify a threat as serious if it was made by a student above the elementary grades (odds ratio 0.57; 95% lower and upper bound 0.42-0.78), a student receiving special education services (1.27; 1.00-1.60), involved battery (1.61; 1.20-2.15), homicide (1.40; 1.07-1.82), or weapon possession (4.41; 2.80-6.96), or targeted an administrator (3.55; 1.73-7.30). Student race and gender were not significantly associated with a serious threat determination. The odds ratio that a student would attempt to carry out a threat classified as serious was 12.48 (5.15-30.22). These results provide new information on the nature and prevalence of threats in schools using threat assessment that can guide further work to develop this emerging school safety practice. Impact and Implications: Virginia public schools are using threat assessment teams to prevent student violence. Based on a sample of 1,865 threat cases, this study found that teams were more likely to identify a threat as serious if the student was above the elementary grades and receiving special education services, if the threat involved battery, homicide, or weapon possession, or targeted an administrator. Although few threats were attempted, a threat judged to be serious was about 12 times more likely to be attempted than a threat not judged to be serious.

Self-report surveys are widely used to measure adolescent risk behavior and academic adjustment, with results having an impact on national policy, assessment of school quality, and evaluation of school interventions. However, data obtained from self-reports can be distorted when adolescents intentionally provide inaccurate or careless responses. The current study illustrates the problem of invalid respondents in a sample (N = 52,012) from 323 high schools that responded to a statewide assessment of school climate. Two approaches for identifying invalid respondents were applied, and contrasts between the valid and invalid responses revealed differences in means, prevalence rates of student adjustment, and associations among reports of bullying victimization and student adjustment outcomes. The results lend additional support for the need to screen for invalid responders in adolescent samples.

The overuse of school suspensions has been linked to a host of negative outcomes, including racial disparities in discipline. School climate initiatives have shown promise in reducing these disparities. The present study used the Authoritative School Climate Survey--which measures disciplinary structure and student support as key measures of school climate--to investigate an association between teacher and student perceptions of school climate and suspension rates in a statewide sample of middle schools. Regression analyses controlling for school-level poverty and school size found that elements of authoritative climate, particularly structure, distinguish high- and low-suspending schools. Schools with high levels of student- and teacher-reported structure had lower overall suspension rates and a lower gap between Black and White suspension rates. These findings can be used to guide school climate initiatives to reduce racial disparities in school discipline.

School psychologists are frequently called upon to assess students who have made verbal or behavioral threats of violence against others, a practice commonly known as threat assessment. One critical issue is whether the outcomes of a threat assessment generate the kind of racial disparities widely observed in school disciplinary practices. In 2013, Virginia became the first state to mandate threat assessment teams in all public schools. This study examined the disciplinary consequences for 1,836 students who received a threat assessment in 779 Virginia elementary, middle, and high schools during the 2014-2015 school year. Multilevel logistic regression models found no disparities among Black, Hispanic, and White students in out-of-school suspensions, school transfers, or legal actions. The most consistent predictors of disciplinary consequences were the student's possession of a weapon and the team classification of the threat as serious. We discuss possible explanations for the absence of racial/ethnic disparities in threat assessment outcomes and cautiously suggest that the threat assessment process may reflect a generalizable pathway for achieving parity in school discipline.

School climate is widely recognized as an important factor in promoting student academic achievement. The current study investigated the hypothesis that a demanding and supportive school climate, based on authoritative school climate theory, would serve as a protective factor for students living with 1 or no parents at home. Using a statewide sample of 56,508 middle school students from 415 public schools in 1 state, results indicated that student perceptions of disciplinary structure, academic demandingness, and student support all had positive associations with student self-reported grade point average (GPA). In addition, findings showed that academic expectations and student support were more highly associated with GPA for students not living with any parent. Implications for policy and practice are discussed.

This study examined the relations between the schoolwide prevalence of teasing and bullying (PTB) and schoolwide academic performance in a sample of 271 Virginia middle schools. In addition, the study examined the mediating effects of student engagement. A three-step sequence of path models investigated associations between schoolwide PTB and state-mandated Standards of Learning test pass rates, with effects examined both directly and indirectly through student engagement while controlling for important school-level characteristics. Separate models were examined for two 7th-grade and four 8th-grade tests. Results indicated that higher levels of both teacher and student perceptions of schoolwide teasing and bullying were significantly associated with lower achievement pass rates and student engagement. The relationship between perceptions of schoolwide teasing and bullying and achievement was partially mediated by student engagement. These findings bring new support for the need for schoolwide interventions to reduce teasing and bullying among middle school students.

Bullying among youth is recognized as a serious student problem, especially in middle school. The most common approach to measuring bullying is through student self-report surveys that ask questions about different types of bullying victimization. Although prior studies have shown that question-order effects may influence participant responses, no study has examined these effects with middle school students. A randomized experiment (n = 5,951 middle school students) testing the question-order effect found that changing the sequence of questions can result in 45% higher prevalence rates. These findings raise questions about the accuracy of several widely used bullying surveys.

Although school climate has long been recognized as an important factor in the school improvement process, there are few psychometrically supported measures based on teacher perspectives. The current study replicated and extended the factor structure, concurrent validity, and test-retest reliability of the teacher version of the Authoritative School Climate Survey (ASCS) using a statewide sample of high school teachers. Multilevel confirmatory factor analyses based on surveys completed by 12,808 high school teachers from 302 schools found that factors of disciplinary structure and student support were associated to varying degrees with the teacher reports of the prevalence of student teasing and bullying and student engagement. These findings provide some empirical support for the use of the teacher version of the ASCS in high schools.

This study tested the association between school-wide measures of an authoritative school climate and high school dropout rates in a statewide sample of 315 high schools. Regression models at the school level of analysis used teacher and student measures of disciplinary structure, student support, and academic expectations to predict overall high school dropout rates. Analyses controlled for school demographics of school enrollment size, percentage of low-income students, percentage of minority students, and urbanicity. Consistent with authoritative school climate theory, moderation analyses found that when students perceive their teachers as supportive, high academic expectations are associated with lower dropout rates.

Aggression toward teachers is linked to burnout and disengagement from teaching, but a positive school climate may reduce aggression and associated teacher distress. Using authoritative school climate theory, the study examined whether schools with high disciplinary structure and student support were associated with less aggression and less distress. The sample of 9,134 teachers in 389 middle schools came from the Virginia Secondary School Climate Survey, a statewide survey administered to all public schools with 7th and 8th grade enrollment. The majority of teachers (75%) were female. More than half (53%) reported that they had more than 10 years of teaching experience; 23% reported 6 to 10 years; 24% reported 1 to 5 years. Students reported on the degree to which their schools were structured and supportive. Teachers reported on their experiences of aggression by students, their level of distress, and their feelings of safety. Staff-related infractions computed from Department of Education records were also used. Multilevel modeling revealed that teachers in authoritative schools experienced less aggression and felt safer and less distressed. Lower aggression by students mediated the association between more authoritative schools and lower distress such that more structured and supportive schools had greater teacher safety and, in turn, less distress. The findings support the idea that more structured and supportive schools relate to greater safety for teachers and, in turn, less distress. Research limitations and implications for practice are discussed.

Advances in multilevel modeling techniques now make it possible to investigate the psychometric properties of instruments using clustered data. Factor models that overlook the clustering effect can lead to underestimated standard errors, incorrect parameter estimates, and model fit indices. In addition, factor structures may differ depending on the level of analysis. The current study illustrates the application of multilevel factor analytic techniques using a large statewide sample of middle school students (n = 39,364) from 423 schools. Both multilevel exploratory and confirmatory factor analyses were used to investigate the factor structure of the Positive Values Scale (PVS) as part of a school climate survey. Results showed that for the PVS, a two-correlated factor model at Level 1 and a one-factor model at Level 2 best fit the data. Implications and guidance for applied researchers are discussed.

Bully victimization is associated with lower academic performance for individual students; however, less is known about the impact of bullying on the academic performance of the school as a whole. This study examined how retrospective administrator reports of both the prevalence of teasing and bullying (PTB) and the use of evidence-based bullying prevention efforts might be associated with school-wide performance on 11 state-mandated achievement tests. Hierarchical regression analyses conducted at the school level with 301 Virginia high schools found that principal reports of both PTB and bullying prevention efforts were associated with the proportion of students that passed achievement testing. Findings could not be attributed to the proportion of White students in the school, student poverty, school size, or urban location, which were statistically controlled.

School climate is widely recognized as an important influence on peer victimization in schools. The purpose of this study is to examine how authoritative school climate theory provides a framework for conceptualizing 2 key features of school climate--disciplinary structure and student support--that are associated with 3 measures of peer victimization. Multilevel multivariate modeling in a statewide sample of 39,364 7th- and 8th-grade students attending 423 schools revealed meaningful associations at both the student and school levels of analysis. Higher disciplinary structure was associated with lower levels of prevalence of teasing and bullying, bullying victimization, and general victimization. Higher student support was associated with lower prevalence of teasing and bullying and general victimization. Overall, these findings add new evidence to the theory that an authoritative school climate is conducive to lower peer victimization.

Zero tolerance school discipline practices have been associated with a national increase in suspensions, a practice that has had a disproportionate negative impact on Black students. The present study investigated an association between principal attitudes toward zero tolerance and suspension rates for White and Black students in 306 Virginia high schools. Black suspension rates were more than double White suspension rates. Regression analyses controlling for student poverty and school enrollment showed that principal endorsement of zero tolerance was moderately associated with suspension rates for both White and Black students, but was not associated with the size of the racial disparity. Paired-samples t tests showed statistically significant differences in the types of offenses that resulted in suspensions, with Black students significantly more likely to be suspended for disruptive offenses and White students more likely to be suspended for alcohol- and drug-related offenses.

This study examined the use of peer nominations to identify victims of bullying in a sample of 7,889 students (grades 3-12). The overwhelming majority reported positive responses to the survey process, which used a randomized design for online or paper administration. School counselors interviewed students who had three or more nominations and saw confirmed victims for follow-up. Although further study is needed, these results support school counselor use of peer nominations to identify victims of bullying.

The Authoritative School Climate Survey was designed to provide schools with a brief assessment of 2 key characteristics of school climate--disciplinary structure and student support--that are hypothesized to influence 2 important school climate outcomes--student engagement and prevalence of teasing and bullying in school. The factor structure of these 4 constructs was examined with exploratory and confirmatory factor analyses in a statewide sample of 39,364 students (Grades 7 and 8) attending 423 schools. Notably, the analyses used a multilevel structural approach to model the nesting of students in schools for purposes of evaluating factor structure, demonstrating convergent and concurrent validity and gauging the structural invariance of concurrent validity coefficients across gender. These findings provide schools with a core group of school climate measures guided by authoritative discipline theory.

This prospective study of 276 Virginia public high schools found that the prevalence of teasing and bullying (PTB) as perceived by both 9th-grade students and teachers was predictive of dropout rates for this cohort 4 years later. Negative binomial regression indicated that one standard deviation increases in student- and teacher-reported PTB were associated with 16.5% and 10.8% increases in the number of dropouts, respectively, after controlling for the effects of other predictors, including school size, student body poverty and minority composition, community crime rates, and performance on standardized achievement testing. The predictive values of student and teacher perceptions of PTB were comparable in magnitude to the predictive values for other commonly recognized correlates of dropout rates. These results provide new evidence that the prevalence of peer victimization in high school is an important factor in high school academic performance. (Contains 3 tables.)

Hierarchical regression analyses conducted at the school level found that the perceived prevalence of teasing and bullying was predictive of schoolwide passing rates on state-mandated achievement testing used to meet No Child Left Behind requirements. These findings could not be attributed to the proportion of minority students in the school, student poverty, school size, or personal victimization, which were statistically controlled for. Measures of the prevalence of teasing and bullying were obtained from a statewide survey of 7,304 ninth-grade students and 2,918 teachers aggregated into school-level scores for 284 Virginia high schools. These results support the need for greater attention to the effect of teasing and bullying on high school student performance on high-stakes testing.

Most research on school climate focuses on student well-being, with less attention on the safety of school faculty. The current study examined the relationship between an authoritative school climate (characterized by high levels of student support and disciplinary structure) and both teacher reports of victimization and school records of threats against staff. Regression analyses in a statewide sample of 280 high schools showed that structure (as measured by student- and teacher-reported clarity of school rules) and support (as measured by teacher-reported help seeking) were associated with less teacher victimization, after controlling for school and neighborhood demographics. Support, but not structure, was a consistent predictor of school records of threats against faculty. These findings offer implications for improving the workplace for teachers and staff. (Contains 2 tables.)

Authorities in education and law enforcement have recommended that schools use a threat-assessment approach to prevent violence, but there is relatively little research on characteristics and outcomes of threats among students. The current study examined student reports of threat experiences in a sample of 3,756 high school students. Approximately 12% of students reported being threatened at school in the past 30 days, but only 23% of threatened students regarded the threat as serious and just 26% reported the threat to school authorities. Only 9% of students who received a threat reported that it was carried out. Five reasons why students did not report threats were identified. Logistic regression analyses identified student and threat characteristics associated with threat reporting and outcome. These findings provide new information about the prevalence and nature of student threats that can inform a threat assessment approach to school violence prevention. (Contains 4 tables.)

This randomized controlled study examined disciplinary outcomes for 201 students who made threats of violence at school. The students attended 40 schools randomly assigned to use the Virginia Student Threat Assessment Guidelines or follow a business-as-usual disciplinary approach in a control group. Logistic regression analyses found, after controlling for student gender, race, school level, and threat severity, that the 100 students in the threat assessment group schools were more likely to receive counseling services (odds ratio [OR] = 3.98) and a parent conference (OR = 2.57), and less likely to receive a long-term suspension (OR = 0.35) or alternative school placement (OR = 0.13) than the 101 students in the control group schools. Implementation fidelity was associated with decreased long-term suspension (OR = 0.73). These results provide strong empirical support for the use of student threat assessment in primary and secondary schools. (Contains 3 tables.)

School violence research is often concerned with infrequently occurring events such as counts of the number of bullying incidents or fights a student may experience. Analyzing count data using ordinary least squares regression may produce improbable predicted values, and as a result of regression assumption violations, result in higher Type I errors. Count data are optimally analyzed using Poisson-based regression techniques such as Poisson or negative binomial regression. We apply these techniques to an example study of bullying in a statewide sample of 290 high schools and explain how Poisson-based analyses, although less familiar to many researchers, can produce findings that are more accurate and reliable, and are easier to interpret in real-world contexts. (Contains 5 tables and 3 figures.)

This quasi-experimental study examined the adoption of the Virginia Student Threat Assessment Guidelines in 23 high schools. After training, school administrators and other staff members demonstrated substantial increases in knowledge of threat assessment principles and decreased commitment to zero tolerance approaches. Schools using the guidelines showed a 52% reduction in long-term suspensions and a 79% reduction in bullying infractions from the pretraining year to the posttraining year, in contrast to a control group of 26 schools not using the guidelines. (Contains 3 tables and 2 figures.)

This study examined the association between school suspension rates and dropout rates in a statewide sample of 289 Virginia public high schools. The contribution of suspension rates on dropout rates was examined for both Black and White students, after controlling for school demographics (school racial composition, percentage of students eligible for Free and Reduced Price Meals, urbanicity), and school resources (per pupil expenditure). Because student attitudes also might influence suspension rates, the prevalence of aggressive attitudes and rejection of school rules among students were used as additional predictors. Hierarchical regression analyses using schools as the unit of analysis found that, after entering both school demographics and student attitude measures, schools with high suspension rates tended to have high dropout rates. There were comparable findings for both White and Black students, although school suspension rates were more strongly associated with White dropout rates than Black dropout rates. These findings contribute new evidence that suspension policies may have an adverse effect on student completion of high school. (Contains 4 tables.)

School counselors frequently use self-report surveys to assess bullying despite little research on their accuracy. In this study, counselor follow-up interviews found that only 24 (56%) of 43 middle school students who self-identified as victims of bullying could be confirmed as actual victims. Other students described peer conflicts that did not constitute bullying, mismarked the survey, or reported previous bullying. Counselor judgments were supported by peer-nomination data and other survey responses indicative of victimization. (Contains 1 table.)

The Virginia Student Threat Assessment Guidelines were developed in response to studies of school shootings conducted by the U.S. Federal Bureau of Investigation, U.S. Secret Service, and U.S. Department of Education that recommended schools should adopt a threat assessment approach to prevent targeted violence. This article reviews the development and field-testing of the guidelines in a series of studies, and then describes the challenges of conducting a randomized controlled trial of threat assessment. The design, measurement, and logistical challenges of conducting rigorous research on student threat assessment are discussed. (Contains 1 figure.)

The Virginia Student Threat Assessment Guidelines were developed to help multidisciplinary school-based teams use a decision tree to evaluate student threats and take appropriate preventive action. A main goal of this approach is to allow school-based teams to recognize and respond to the developmental complexities of children and adolescents without resorting to the use of zero tolerance discipline. The model takes a triage approach that involves progressively more extensive assessment and intervention according to the severity of the threat and the student's intentions. The article summarizes two field test studies of the model, a study of training effects on staff attitudes and knowledge about violence prevention, and a quasi-experimental study showing that secondary schools using the model enjoyed a more positive school climate characterized by less bullying and greater willingness among students to seek help for threats of violence. (Contains 1 figure and 22 notes.)

To determine whether larger high schools have more student victimization than smaller schools, this study examined a statewide sample of approximately 7,431 ninth-grade students and 2,353 teachers in 290 Virginia high schools participating in the Virginia High School Safety Study. School size was distinguished from the proportion of students receiving free or reduced-price meals, percentage of minority students, ethnic diversity (heterogeneity), and urbanicity. In larger schools, teachers and students reported that they perceived more bullying and teasing taking place, but student self-reports of being a victim of bullying were not associated with school size. Additionally, school discipline records showed that although the total number of incidents was higher, the rate of bullying offenses was lower in larger schools. Similar results were found for measures of student threats and physical assaults. These findings raise the possibility that the link between larger schools and higher student victimization is an illusion based on perceived frequency rather than rates of victimization.

In this study we examined authoritative discipline theory, which posits that 2 complementary aspects of school climate--structure and support--are important for adolescents' safety in school. Using a statewide sample of over 7,300 ninth-grade students and 2,900 teachers randomly selected from 290 high schools, we showed, using hierarchical linear modeling, that consistent enforcement of school discipline (structure) and availability of caring adults (support) were associated with school safety. Structure and support were associated with less bullying and victimization after we controlled for size of school enrollment and the proportion of ethnic minority and low-income students. These findings suggest that discipline practices should not be polarized into a "get tough" versus "give support" debate because both structure and support contribute to school safety for adolescents.

This study examined the concurrent validity of the Olweus Bully/Victim Questionnaire (BVQ) in a convenience sample of 202 middle school students in central Virginia. This appears to be the first published study to compare BVQ reports of being bullied and of bullying others with independent criteria not subject to shared method variance. Self-reported bullying on the BVQ was significantly correlated with peer nominations for bullying (r = 0.12, p less than .05) and academic grades (r = -0.15, p less than 0.05), but not disciplinary infractions. Self-reported victimization was significantly correlated with peer nominations for victimization (r = 0.42, p less than 0.01) and academic grades (r = -0.12, p less than 0.01). These results provide only modest support for the concurrent validity of the BVQ and raise concern about reliance on student self-report to measure school bullying. (Contains 3 tables and 1 note.)

School shootings have generated great public concern and fostered a widespread impression that schools are unsafe for many students; this article counters those misapprehensions by examining empirical evidence of school and community violence trends and reviewing evidence on best practices for preventing school shootings. Many of the school safety and security measures deployed in response to school shootings have little research support, and strategies such as zero-tolerance discipline and student profiling have been widely criticized as unsound practices. Threat assessment is identified as a promising strategy for violence prevention that merits further study. The article concludes with an overview of the need for schools to develop crisis response plans to prepare for and mitigate such rare events. (Contains 2 figures, 1 table, and 1 note.)

This study tested a model for understanding peer bullying as the product of aggressive attitudes and insecure attachment. A sample of 110 sixth grade students completed self-report measures that assessed attitudes toward the use of aggressive behaviour with peers and distinguished secure from insecure parental attachment. Bullying behaviour was assessed using self- and peer-report. Path analyses indicated that aggressive attitudes mediated a relationship between insecure attachment and bullying behaviour. These findings have theoretical and applied implications for bullying prevention. (Contains 1 table and 2 figures.)

The School Climate Bullying Survey (Cornell & Sheras, 2003) is a self-report survey used to measure attitudes and behaviors associated with school bullying. Two studies were conducted to examine the valid use of its three school climate scales: (a) Prevalence of Teasing and Bullying, (b) Aggressive Attitudes, and (c) Willingness to Seek Help. In Study 1, exploratory and confirmatory factor analyses were performed with a sample of 2,111 students from four middle schools and established reasonable fit for 20 items with their hypothesized scales. Multigroup confirmatory factor analyses revealed good overall model fit. In Study 2, regression analyses using school-level measures aggregated from 7,318 ninth-grade students attending 291 Virginia public high schools indicated that the three scales were related to meaningful criteria for school disorder.

Threat assessment has been widely recommended as a violence prevention approach for schools, but there are few empirical studies of its use. This nonexperimental study of 280 Virginia public high schools compared 95 high schools using the Virginia threat assessment guidelines (Cornell & Sheras, 2006), 131 following other (i.e., locally developed) threat assessment procedures, and 54 not using a threat assessment approach. A survey of 9th grade students in each school obtained measures of student victimization, willingness to seek help for bullying and threats of violence, and perceptions of the school climate as caring and supportive. Students in schools using the Virginia threat assessment guidelines reported less bullying, greater willingness to seek help, and more positive perceptions of the school climate than students in either of the other 2 groups of schools. In addition, schools using the Virginia guidelines had fewer long-term suspensions than schools using other threat assessment approaches. These group differences could not be attributed to school size, minority composition or socioeconomic status of the student body, neighborhood violent crime, or the extent of security measures in the schools. Implications for threat assessment practice and research are discussed. (Contains 2 tables.)
