The Avaliação Longitudinal da Desistência Escolar (ALDE, Longitudinal Assessment of School Dropout) is the first nationally representative mixed-method longitudinal survey in Mozambique. Since 2018, the ALDE survey has annually collected longitudinal, nationally representative data from around 5,400 primary school students (from grades 1 to 7) in 60 schools across all eleven provinces in the country. This report presents the results of the quantitative data collected in 2019 and focuses on the determinants of school dropouts in the country. When children leave school prematurely, not only is their learning interrupted, but the trajectories of their future opportunities and lives are forever altered. This report explores the multidimensional process of school dropouts, investigating how individual, household, community and school-level factors interact to lead children in Mozambique to dropout of education. Through this analysis, the report provides important and actionable recommendations to improve education policy in Mozambique towards its journey to achieve learning for every child.
