Early Development Instrument (EDI)

 EDI, or Early Development Instrument, is a questionnaire used by Kindergarten teachers across Alberta to assess overall development in a child’s first five years of life.  The EDI measures children’s ability to meet age-appropriate developmental expectations in five general domains:  Physical Health and Wellbeing, Social Competence, Emotional Maturity, Language & Cognitive Development, and Communication Skills & General Knowledge.   It was developed at the Offord Centre for Child Studies at McMaster University.
