This report presents a detailed description of baseline data collection and intervention preparation activities conducted as part of the project `Early Childhood Development for the Poor: Impacting at Scale’, a project primarily funded by the Eunice Kennedy Shriver National Institute of Child Health & Human Development of the National Institutes of Health (NIH) and the Strategic Impact Evaluation Fund (SIEF).

The project is a collaboration between Yale University (USA), The Institute for Fiscal Studies (UK), University College London (UK), University of Pennsylvania (USA), the Centre for Early Childhood Education and Development (India), Pratham Education Foundation- ASER Centre (India) and the Abdul Latif Jameel Poverty Action Lab SA (India).

The project aims to establish scientifically the impact of Early Childhood Development policies that can form the basis for the design of low cost and sustainable ECD strategies to supplement current policy such as the ICDS.
