School Readiness (EDI)

Early Development Instrument (EDI)

The EDI is a teacher-completed instrument that measures children's school readiness for grade one on 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 who score below the 10th percentile in one or more EDI domains are considered to be vulnerable to not be able to meet the demands of school, which could impact their achievement of school success.

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

In 2010, 30.3% of children surveyed in Peel were vulnerable on one or more domain. Brampton and Mississauga had above-average vulnerability while Caledon had below-average vulnerability.

How can EDI data be used?

The EDI is not an evaluation of how well early years programs and services are offered in a community. Since the EDI is a measure of school readiness, results can show areas of weakness in school readiness to which programs and services can respond.

EDI also provides an opportunity for ELCC partners (schools, providers etc.) to analyze the development of children as they enter school and plan for optimal school transition.

EDI data can be used in combination with other information such as census data, family information, and health and community measures to provide a more complete picture of the factors that can impact early childhood development.
