This briefer reports the results of the Accelerated School Readiness (ASR) program, offered by the LEGO Foundation Childhood Development Activity in Ethiopia. This was an intensive eight-week play-based, holistic development and learning program for children without pre-primary education exposure. In the Summer of 2024, 11,141 children aged 6 years or older, in crisis-affected areas of Oromia, Somali, Amhara, Tigray, and Afar participated in the ASR play-based learning program. Children participating in ASR improved their early learning skills by 28 percentage points. Learning gains were observed for all measured school readiness domains. After attending ASR, children also demonstrated more attention to instructions, heightened confidence and motivation to complete tasks, and an increase in curiosity and pleasure in participating in the assessment learning tasks.
