Secondary school enrolment in Uganda has historically favoured males over females. Recently, however, researchers have reported that the secondary enrolment gender gap has significantly diminished, and perhaps even disappeared in Uganda. Even if gender parity is being achieved for enrolment broadly, there may be a gender gap concerning age-appropriate enrolment. This is an important next step in educational research concerning gender equity in education worldwide. There is little information about what individual, family and regional factors influence age-appropriate enrolment. Therefore, this study investigates a potential age-appropriate enrolment gender gap for secondary-aged youth, and examines the factors that influence gendered enrolment behaviours in Uganda. Implications for policy, practice, and further research are discussed. (Contains 1 figure and 4 tables.)
