The quasi-experimental study aims at investigating a large-scale, multi-pronged Early Childhood Education programme in public schools spread across 11 districts in South Punjab. The intervention included, among other things, providing ECE training to teachers, providing the schools with ECE caregivers, making available material for teaching and learning, and upgrading ECE classrooms. By comparing the effects of the intervention in treatment and control groups, the study will generate data driven evidence on ‘what works’ to deliver quality ECE education in a low-income setting. The evaluation has immediate policy relevance, as it will inform the Government of Punjab’s decisions on scaling similar interventions across other districts in Punjab.
