Starting Strong III: A Quality Toolbox for Early Childhood Education and Care has identified five policy levers that can encourage quality in ECEC, having positive effects on early child development and learning. We would like to thank all those who gave their time to respond to our questions, provide background documents, comments on preliminary drafts and validate the information for accuracy. We would also like to thank consultants Janice Heejin Kim and Matias Egeland who worked on sections of the preliminary drafts as part of the OECD team on ECEC.
