Advanced Placement and International Baccalaureate Performance Differences as a Function of Gender and School Size

Morris, J., & Slate, J. R. (2012). 3 (1)

Student participation and student performance on the Advanced Placement and International Baccalaureate exams for the 2008-2009 school year was examined to ascertain the extent to which differences were present as a function of high school size and student gender. Using Academic Excellence Indicator System data for traditionally configured high schools in Texas, statistically significant differences were yielded. In the 2008-2009 school year, girls had higher participation rates than did boys. Moreover, girls outperformed boys regardless of school size. The performance of boys and girls on these exams differed as a function of school size, with students in larger size high schools participating at a higher rate and outperforming students at smaller size high schools. Implications of the findings are discussed and suggestions for further research are made.
