The 1998 reauthorization of the Higher Education Act requires all states to report annually to the U.S. Department of Education the number of prospective teachers at each teacher training institution who pass their own state tests for licensure. However, the law left decisions on what tests to require in each field, what to assess on them, and their passing scores up to each state. To determine the content knowledge in reading and mathematics that subject tests for prospective special education teachers assess, this study drew on information available on the Web sites for Educational Testing Service, the American Board for Certification of Teacher Excellence, and National Evaluation Systems. It examined the extent to which these tests address three research-based components of reading pedagogy (instruction in phonemic awareness, phonics, and vocabulary knowledge), the weights attached to knowledge of these three components, and the quality of the sample questions provided for them. It estimated the percentage of test items addressing mathematics content and these three components on each test. It also analyzed the descriptions of ETS's tests of "principles of teaching and learning" to see whether these tests assess understanding and use of educational theories that underlie effective research-based practices. The findings of this study suggest that one solution for ensuring that prospective special education teachers begin their teaching careers with a substantial amount of research-based knowledge of reading instruction is to require them to take a dedicated test of research-based reading instructional knowledge, as do California, Massachusetts, and Virginia, in addition to any other tests required for their license. To ensure an adequate amount of relevant mathematical knowledge, states might consider replicating the 40-item test of mathematics content that Massachusetts will require of all aspiring elementary and special education teachers in 2009. States will also need to design their own tests of basic principles of teaching to ensure that they assess knowledge of educational theories that underlie effective research-based practices. Profiles of Thirteen Tests for Elementary and Sometimes Other Teachers are appended. (Contains 1 figure, 2 tables and 5 footnotes.)

Effects of the high school environment, part-time university instructors, and classroom ethnic/racial diversity on first-year student preparation and enrollment persistence are estimated via hierarchical linear and logistic regression. After controlling for student socio-demographic characteristics and motivation to enter college, high school attributes bear little relevance to level of academic preparation at the start of the first year of study. In contrast, academic performance of low-income students at the end of the first year is negatively associated with several features of the high school environment. There is little evidence that student persistence is negatively affected by exposure to part-time instructors during the first year in college. Ethnic/racial diversity in the classroom appears to slightly enhance persistence of non-Asian minority students, but shows no positive relationship with cognitive growth. Unmet financial need marginally increases the dropout risk of students taking greater course loads net of socio-demographic background, academic preparation, first-year grades, on-campus residency, and type of aid received. Results are based on institutional matriculation records of 2,800 first-year students at a moderately selective public university and official high school accountability reports collected by the state's department of education.

The greatest limitation in establishing causality in observational studies on the effect of financial aid is the presence of endogeneity or selection bias associated with aid status. To control for this statistical confoundedness that besets the research corpus to date, this study estimates the effect of financial aid on freshmen retention at a moderately selective, public university using propensity score-matching in multi-stage regression analyses. The correlational pattern that emerged from twenty-four logit models suggests higher-income students accrue a retention benefit from financial aid, unlike low-income students, net of first-year academic experience and type and amount of aid received. Conversely, retention of low-income freshmen is more likely due to academic performance compared to those from high-income background. Findings on the effect of aid are consistent with the economics of moral hazard and unobservable behavior. (Contains 6 footnotes, 8 tables, and 2 figures.)
