The Early Development Instrument (EDI) Fact Sheet
2015 Human Early Learning Partnership
The EDI is a questionnaire that is used province-wide. It was developed by researchers at the Offord Centre for Child Studies to measure patterns and trends in child development in populations of children. The questionnaire is completed by kindergarten teachers for children in their classes. They are filled out in February, after teachers have had the chance to get to know their students. This ensures that teachers are able to answer the questions for each student knowledgeably. The EDI includes 104 questions and measures five important areas of early child development. These areas are good predictors of adult health, education and social outcomes.
