The aim is to recruit 60 preschools and 1200 children aged 3-5 years in one county in the western part of Norway to allow for detecting small to moderate effect sizes and ensuring a heterogeneous sample of preschools for the study of implementation. Children's physical development, children's socio-emotional and cognitive development, and intervention implementation will be investigated.
