The Multi-Country Study on Inclusive Education (MCSIE) is the first major, multi-country effort by USAID to investigate what works in supporting children with disabilities to learn to read. The study aims to derive lessons about what works to sustainably advance teaching and learning outcomes for children with disabilities in varying contexts. USAID and its partners will use this information to inform adaptations to its activities in Cambodia, Malawi, and Nepal, as needed, and plan for new inclusive early grade reading programming globally.
