Children’s Developmental Health at School Entry

Early Development Instrument (EDI)

The EDI is a validated teacher-completed instrument that measures children’s developmental health at school entry across five domains:

  • Physical health and well-being;
  • Social knowledge and competence;
  • Emotional health/maturity;
  • Language and cognitive development; and,
  • General knowledge and communication skills.

Children are considered vulnerable if they score below the Ontario Baseline vulnerability cut-off point in one or more of the five EDI domains. Vulnerable children are struggling to keep up and are at risk of not being able to meet the demands of school and beyond.

Are children in Peel vulnerable on one or more EDI domain?

In 2018, 31.0% of children reported in Peel were vulnerable on one or more domain. Brampton (30.8%) and Mississauga (32.1%) had slightly higher vulnerability scores while Caledon (21.8%) had the lowest vulnerability.

How can EDI data be used?

The EDI helps to understand and measure age-appropriate developmental expectations at school entry. It provides an overall measure based on children’s developmental health outcomes that have potential long-term consequences.

The data collected from the EDI is encouraged to facilitate and mobilize communities to monitor the developmental health of young learners.

The EDI data can also be used as an additional variable with other data points such as Census data in order to provide a more complete picture of the factors that can impact early childhood development.
