This World Bank Working Paper discusses equity and efficiency issues in secondary education transitions in Sub-Saharan Africa. Its main purpose is to identify and analyze national, regional, and local measures that may lead to the development of more efficient and seamless transitions between post-primary education pathways. In most African countries student transition from primary to junior secondary is still accompanied by significant repetition and dropout. Transitions within the secondary cycle also cause significant losses and should use more effective assessment and selection methodologies. According to global trends, Africa needs to revisit its post-primary structures to provide more diversified (academic and non-academic) pathways of learning which respond better to the continent's present economic and social realities. In the end, the main goal should be to produce young people who can become productive citizens and lead healthy lives, as demonstrated by middle and higher-income economies.
