Early Development Instrument (2015), SDA 2017


Provide Feedback
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 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.

Early Development Instrument (EDI) Scores for 2014-2015 are grouped into Service Delivery Areas (2017). If you would like to compare the data to the 2010 EDI scores, please use the 2015 EDI table that is provided at the 2012 SDA Level.

  1. Records are aggregated to achieve anonymity.
