Big Gender Gaps for 12th Graders on NAEP Exams
Results from the 2005-2006 National Assessment of Educational Progress (NAEP) tests:
For 12th graders taking the Economics subject exam in 2006 (data available here), the mean score for male students was 152 and the mean score for female students was 148, and that gap of 4 points was statistically significant at the 1% level (p = .0071). Likewise, in 2005 there was a statistically significant gender gap in favor of males by 4 points on the Science exam (149 average for males vs. 145 for females), and a statistically significant two point gap for the Math exam (151 average for males vs. 149 females).
In contrast, there was a statistically significant gender gap in favor of females by 13 points on the reading exam (292 mean for females vs. 279 for males), and a statistically significant difference of 18 points in favor of females on the writing exam (162 mean vs. 144).
