The purpose of this study was to understand enrollment and performance differences between males and females in higher level International Baccalaureate (IB) Diploma Programme (DP) STEM courses. This study analyzed the performance and enrollment of 355,688 DP students in higher level STEM courses. The research also explored country level differences. The enrollment research questions are evaluated using chi-square tests, frequency tables, and histograms. Performance research questions are analyzed with hierarchical linear regression and ANOVA with post hocs and Cohen’s d effect size measures. Results suggest that females enroll much less frequently in higher level DP STEM courses. Females and males perform equally well.
