The Australian Government is supporting the Government of Lao PDR to undertake significant primary education reforms through its flagship Basic Education Quality and Access in Lao PDR program (BEQUAL), including a new primary curriculum. Phase 1 of BEQUAL (2015-22) supported the Ministry of Education and Sports (MoES) to rollout the new primary curriculum in schools, starting with Grade 1 (G1) in 2019. Specific teaching practices were introduced, including active learning, student-centred learning approaches, formative assessment, and a phonics approach to teaching reading. New practices were complemented by face-to-face orientation training and grants in BEQUAL target districts to strengthen communities of practice, self-access learning, monitoring visits, and teacher cluster meetings. Part of a multi-year study series, the Education Analytics Service (EAS) investigated how BEQUAL improved teaching quality and student learning outcomes.
