This report provides an overview of the main results for Lao PDR from the 2019 Southeast Asia Primary Learning Metrics (SEA-PLM) learning assessment. The regional assessment measured achievement levels in reading, writing and mathematics of Grade 5 students in six countries: Cambodia, Lao PDR, Malaysia, Myanmar, the Philippines and Vietnam. The results in this report address five key research objectives of the 2019 SEA-PLM assessment: 1) To measure Grade 5 student achievement levels in the core subjects of reading in Lao language, writing and mathematics; 2) To describe Lao PDR student and teacher SEA-PLM results on a series of “global citizenship” indicators; 3) To assess the equity of student learning outcomes in Lao PDR and the degree to which these results vary significantly by key contextual factors such as gender, location, ethnicity and socioeconomic status (SES); 4) To identify teacher, school and classroom characteristics that are associated with higher and lower results on the SEA-PLM assessment; 5) To translate the key findings into actionable policy recommendations.
