The British Department for International Development (DFID) has partnered with the Ugandan Ministry of Education and Sports (MoES) to conduct empirical research on inefficiencies in the Ugandan education system. This research will help the Ministry better understand the severity, causes, and consequences of an enrolment bulge in early primary classes in Uganda. Specifically, this study is investigating the magnitude of repetition in primary 1. It encompasses a nationally representative sample of pupils, and uses information from interviews with pupils, parents/guardians, and teachers.
