Effekten af programmet 'Pædagogisk kvalitet i dagplejen'.

We use a large-scale randomized field experiment to examine if a professional development program for family daycare providers that focuses on language and interactions between the provider and the child can improve language and social-emotional skills for children under three years old. Despite careful program implementation consistent with the established practices of the family daycare providers, we find no significant effects on child outcomes. We provide potential explanations for the observed lack of effects, highlighting the need for future research to scrutinize implementation processes and incorporate external evaluations of child outcomes.
