An early step in developing an assessment framework for the Southeast Asia Primary Learning Metrics (SEA-PLM) was determining how to design and construct a single assessment program across all ASEAN member countries. This step needed to take account of the similarities and differences in the curriculum frameworks in each country for the four domains to be assessed through SEA-PLM: Mathematics, Reading, Writing and Global Citizenship. This document presents the outcomes of the curriculum audit realized in 2015-2016 in the domains of Reading, Writing, Mathematics, and Global Citizenship for the following countries: Brunei, Cambodia, Indonesia, Lao PDR, Malaysia, Philippines, Singapore, Thailand, Timor Leste and Vietnam. Limited information was available from Myanmar, due to the national curriculum reform process that was happening at the time of the audit; however some general information was reviewed.
