The EDI is designed for use with whole populations based on geographical or administrative boundaries. It is a questionnaire completed by kindergarten teachers for each student in senior kindergarten.

The EDI measures early child development in 5 domains:

  • physical health and well-being
  • social competence
  • emotional maturity
  • language and cognitive development
  • communication skills and general knowledge

The EDI was developed by researchers at the Offord Centre for Child Studies in McMaster University. The instrument is designed to be interpreted at the group level only.
