In-depth EDI by area of development


This map shows EDI results for five areas of development for communities and subcommunities across Alberta. Summaries of EDI results are also provided for communities and subcommunities, along with pie charts of results for each area of development.


The five areas are: physical health and well-being, social competence, emotional maturity, language and thinking skills, and communication skills and general knowledge. Results are grouped into three categories: developing appropriately (DA), experiencing difficulty (ED) and experiencing great difficulty (EGD). For more information about the EDI, click here.
