The project is a two-year initiative which aims to implement a holistic pre-school model in Nyanza region - Kisumu and Kisii counties in Kenya. To assess the effectiveness and impact of this model into new regions, a series of performance indicators were developed for the collection and analysis of data to inform its success. The findings and recommendations of the study will also contribute towards a better understanding and delivery of Early Childhood Development and Education (ECDE) services at pre-primary school level thereby contributing to the realization of sustainable development goal (SDG) 4.2 of ensuring that all girls and boys have access to quality early childhood development, care, and pre-primary education in preparation for primary education.
