Evidence of gender inequity and inequality in terms of access, retention and performance in secondary education in Sub-Saharan Africa raises many questions. While transition rates from primary to secondary are higher for girls than boys, and the repetition rates are lower, girls still significantly trail behind boys in terms of secondary GER. This study documents and analyzes the extent and nature of gender disadvantage in junior and senior secondary education. It analyzes the causes of this disadvantage and identifies strategies that may be effective in reducing or eliminating it.
