The Early Development Instrument (EDI) is a questionnaire designed to measure children’s development in kindergarten. Designed by Drs. Dan Offord and Magdalena Janus of McMaster University, the EDI is a checklist that kindergarten teachers complete for each child in their class. It is a holistic measure of children's development across five areas: (1) physical health and well-being; (2) social competence; (3) emotional maturity; (4) language and cognitive development; and (5) communication skills. Teachers complete the EDI in February, after they have had several months of interaction with their Kindergarten class.

The EDI questionnaire is completed by kindergarten teachers from across BC for all children in their classes. This is done in 3 year waves. Each wave represents as close as possible a complete province wide survey of all BC school districts. 


Since EDI data is collected in three year waves, it is important to note that not every child who attends kindergarten in a given year in BC will be captured in the EDI dataset. For example, a child attending kindergarten in Vancouver in 2008 would not be included in the EDI data as data was not being collected in that particular geographic region of BC in 2008.

Conditions for access to EDI data

For access to EDI data from 1999 until 2010 (through Population Data BC) researchers must meet all of the following conditions:

  1. The researcher must be from The University of British Columbia, the Human Early Learning Partnership (HELP), or an affiliate or partner of HELP.
  2. The researcher must complete a form (in addition to completion of a Data Access Request (DAR)), which outlines how the researcher project relates to the Early Childhood Development Program of Research. The EDI/HELP Data Steward will have decision-making authority on the relevance to the ECDMP.

    Researchers will have to provide an explanations of one or more of the following:

    • Explain their project's relevance for the overall ECDMP.
    • Does the project contribute in some manner to the psychometrics of EDI?
    • Does the project expand our understanding of ECD relevant for the ECDMP?
    • Does the project contribute in a unique manner that is not identified here?
  3. Researchers are required to share their results with HELP in order to ensure that their project will contribute to the ongoing work of the program of research.
