The Early Development Inventory (EDI) is 104-item questionnaire developed by Dr. Dan Offord and Dr. Magdalena Janus through the Offord Centre for Child Studies in Ontario, Canada. The questionnaire is completed by kindergarten teachers who evaluate each child in five core areas of early childhood development that are found to be good predictors of adult health, social, and educational outcomes: physical health and well-being, language and cognitive development, social competence, emotional maturity, communication skills and general knowledge. Unique to the EDI is that it is an assessment tool at the population level. This means that rather than evaluating individual children, the EDI measures developmental trends and change in populations of children at provincial, regional, and neighbourhood groupings. The information and data gathered from the EDI is intended to help early childhood educators and school administration identify strengths and weaknesses in the communities they serve and to allow them to better advocate for policy and funding changes.

In British Columbia, Canada, the Human Early Learning Project, based in the School of Population and Public Health at the University of British Columbia has supported use of the EDI in kindergartens across the province. Their EDI website provides overviews of early child development and research related to the measure, detailed information of the EDI measure and its administration, maps, data, and reports from multiple waves of data collection, and a library of fact sheets and related publications.

The Human Early Learning Project also has a Middle Years Development Inventory for youth in grades 4 and 7.
