In Rwanda, over 3.5 million children were estimated to be out of school in 2020 when the country closed all schools as a safety measure against the spread of COVID-19. The government quickly developed a national response plan and started the process of hiring teachers, constructing classrooms and training in-service teachers in remote-learning pedagogies. Prior to the lockdown, schools were already experiencing challenges, including low attendance rates. In the post-COVID-19 environment, learning losses are expected to be significant, especially on the acquisition of foundational skills, and will hinder the ministry's efforts to achieve the learning outcomes of its new competence-based curriculum. A Time to Teach study in 2020 in Rwanda found that low teacher attendance was a common problem in primary schools. This study seeks to support the Ministry of Education by providing a comprehensive understanding of secondary school teacher attendance in the country. It builds on findings from the primary schools' study, to understand how attendance challenges may be similar or different across education levels, and more importantly, how these can help inform teacher policy design and implementation.
