Early Development Instrument (EDI)

The Early Development Instrument (EDI) measures children's developmental health at school entry and was created by Dr. Dan Offord and Dr. Magdalena Janus of the Offord Centre for Child Studies at McMaster University. The EDI is a 103-item checklist that is completed by Senior Kindergarten teachers for each child in their class and measures overall developmental health in five general domains: physical health and well-being, social competence, emotional maturity, language and cognitive development, and communication skills and general knowledge. Although it is completed for individual children, the EDI is a population-based measure and is not a diagnostic tool nor is it an indication of a school's performance. The results of the EDI, in combination with other local data are meant to help inform communities about the development of their young children so that they may provide the supports necessary for healthy child development.
