What is the EDI?
The EDI is a 103-item questionnaire completed by kindergarten teachers in the second half of the school year that measures children’s ability to meet age-appropriate developmental expectations in five general domains. After teachers complete the EDI on each individual child in their class, the results are grouped together to give a snap shot of how children are doing across schools, neighbourhoods, cities, or even provinces and countries. The EDI data can be helpful for a variety of different users. The Government can use EDI data to plan early childhood investment, inform policy and program development decisions, or evaluate programs. The use of EDI maps can help focus investments and identify the areas with the highest needs.

Below you will find reports from previous cycles (EDI collection periods). Please note that due to methodological changes over time, numbers in the older reports may not exactly match the '5 Cycles of the EDI' report. An example of a change is that children are now required to have been in class for more than one month to be included in any analyses.
