About

The Early Development Instrument (EDI) is a population level measure of children’s development or well-being developed by Magdalena Janus and Dan Offord at the Offord Centre for Child Studies at McMaster University in Ontario, Canada. The instrument is largely based on the National [Canadian] Longitudinal Survey of Children and Youth, and other existing tests. The EDI combines several areas that have been identified as relevant to children’s school readiness: physical health and well-being, social competence, approaches to learning, emotional maturity, language development, cognitive development, communication skills, and general knowledge. The Early Development Instrument (EDI) is a relatively short and easy to administer tool. Its results can be aggregated to various levels and therefore easily lends themselves to linkages with other population and community data[1].The EDI is used in Canada. Early Childhood is considered a crucial period in a child’s development.

 

The Australian Early Development Index is a successor of the EDI. There is also rising interest for the EDI in the United States[2].

Early Development Instrument

What is the Early Development Instrument (EDI)?

  • EDI developed in Canada by the Offord Centre for Child Studies
  • Teacher-completed checklist on children’s development measured in spring of kindergarten
  • Data is aggregated to a group level (school, neighborhood, city, etc) to provide a population- based measure of children’s development
  • EDI is not reported at the child or class level and is not used as a diagnostic tool for individual children
  • Fills important information gap in US since early development is not consistently measured across schools, districts or communities

What does EDI measure?

  • Five developmental domains
  • Physical health and well-being
  • Social competence
  • Emotional maturity
  • Language and cognitive development
  • Communication skills and general knowledge
  • EDI is linked to child-level demographics
  • Potential to link EDI with parent information
