The Encyclopedia on Early Childhood Development is a project of Abilio - Childhood Knowledge Dissemination Centre, formerly the Centre of Excellence for Early Childhood Development (CEECD), supported by Université Laval and Université de Montréal (Quebec, Canada). Over the years, this organization has built a solid network of international experts who gather, synthesize and comment, in their respective domain of expertise, the most up-to-date scientific knowledge available on the development of young children, from conception to age five. 

The Encyclopedia is intended for service providers, service planners, policy makers and parents.

Most topics are explored from three perspectives: development, services and policy and the papers gathered under each topic are written by internationally renowned experts. 

The syntheses and information sheets (Eyes on...) provide summaries of the most essential knowledge in a lay language suited to various readers. 

The Encyclopedia also features a section entitled Voices from the Field that focuses on a specific environment or region. 

The Encyclopedia is a comprehensive, reliable and easy-to-use reference tool, a unique and free resource devoted to promoting accessibility and knowledge transfer of the best knowledge on early childhood development.


The Encyclopedia on Early Childhood Development is produced by Abilio - Childhood Knowledge Dissemination Centre. The development of the Encyclopedia is made possible thanks to the financial contributions of the Université de Montréal, Université Laval, as well as the Lawson Foundation and Wallace McCain Family Foundation.
