Background: Research on gender differences in intelligence has focused mostly on samples from Western countries and empirical evidence on gender differences from Southeast Asia is relatively sparse., Aims: This article presents results on gender differences in variance and means on a non-verbal intelligence test using a national sample of public school students from the Philippines., Sample: More than 2,700 sixth graders from public schools across the country were tested with the Naglieri Non-verbal Ability Test (NNAT)., Methods: Variance ratios (VRs) and log-transformed VRs were computed. Proportion ratios for each of the ability levels were also calculated and a chi-square goodness-of-fit test was performed. An analysis of variance was performed to determine the overall gender difference in mean scores as well as within each of three age subgroups., Results: Our data show non-existent or trivial gender difference in mean scores. However, the tails of the distributions show differences between the males and females, with greater variability among males in the upper half of the distribution and greater variability among females in the lower half of the distribution.

This paper discusses issues on cross-cultural gifted screening from a Philippine perspective. Research on gifted education in the Philippines, and Southeast Asia in general, is still nascent. The main focus of this review of literature is on equity of the gifted education screening process across wide socioeconomic, cultural, and linguistic differences within the student population. On account of the relative lack of specific literature on Philippine gifted education, this review links the findings in gifted education research from Western-based countries and relates the findings to the Philippine context. For example, although the Philippines do not have as much of an issue of racial inequity in schools as the United States, the same inequity because of socioeconomic factors can be tackled similarly. The implication of alternative assessments, and their utility in cross-cultural gifted education, are also examined.

This study examines the effect of parental education levels (PELs) on the fluid intelligence of Filipino public school students. The data were drawn from a normative study of a nonverbal intelligence test involving more than 2,700 students sampled across the country. As expected, PELs have a significant impact on fluid intelligence as measured through a nonverbal intelligence test. The results indicate that PELs account for an increase of roughly three IQ points for every increment in PEL. Students with college-graduate parents scored significantly higher (d ratio = 0.66) compared to those with parents who never graduated from elementary. However, a comparison of mean scores between PELs that are adjacent (i.e., high school graduate vs. college graduate) shows relatively small differences (d ratio = 0.23 to 0.25).

This is a normative study to investigate the transferability of norms from western-based intelligence tests to Filipino students. More than 2,700 Filipino sixth graders were sampled across the country and administered the Naglieri Nonverbal Ability Test (NNAT). Scores were then compared to the US normative sample. The results showed no significant differences in mean scores and the standardized mean difference is small when scaled scores are used in comparison. However, in situations where the test needs to be used for specific portions of the population such as in the context of gifted education, further analysis revealed that the distribution of scores for the Philippine sample differed significantly from the expected values based on the US norms, particularly in the tail ends of the distribution. In these cases, it may not be valid to transfer the US norms directly to Filipino students without any modification.
