The Early Development Instrument (EDI) is a population based measure developed by the Offord Centre for Child Studies at McMaster University. This questionnaire is completed by Senior Kindergarten teachers in the second half of the year (February/March) and is designed to measure a child’s ability to meet age-appropriate developmental milestones at school entry.

The EDI measures children’s developmental health across five domains: Physical Health & Well-Being, Social Competence, Emotional Maturity, Language & Cognitive Development, and Communication Skills & General Knowledge.  The following infographic presents a brief overview of the results of the EDI for 2018.  You can also download the full report by clicking on the links below.
