The Early Development Instrument:Reports and Resources




A central component of HELP’s child development monitoring system is the Early Development Instrument (EDI), a questionnaire that has been used across BC since 2001 to gather data about children's development at age five. Learn more about the EDI here. EDI data provide essential insights into the health of our children and helps us explore the patterns and trends in their developmental health.

This year, HELP is reporting on data gathered and analyzed from February 2013 to February 2016. The data from these years is referred to as ‘Wave 6’ data. In Wave 6, HELP gathered data for over 43,000 children across the Province. Find below links to a selection of reports and maps that examine six waves of data across a 12 year period (2004-2016) for over 247,000 Kindergarten children.


The EDI BC Provincial Report

Released in October 2016, HELP’s EDI BC: 2016 Provincial Report provides a comprehensive overview of provincial trends that are emerging from over 10 years of data collection and analysis. This interactive report provides an overview of the EDI as well as easy access to five waves of data for each of the EDI scales and newly published EDI subscales data. The online report also offers a link to a comprehensive print version, complete with School District data and maps.

Community Profiles

EDI Community Profiles are comprehensive reports available for all of BC's 59 School Districts. These community profiles explore and synthesize EDI data aggregated by School District and their associated neighbourhoods. These data are based on children’s home postal codes representing children who live in the School District and include children attending public schools and children attending participating Independent and on-reserve schools.

Select a School District from the list below to access current and archived EDI reports and mapping packages. Each School District page provides additional tools and resources to help explore significant changes in EDI vulnerability rates over time at the district and neighbourhood-level.


Interactive Maps

Using our updated interactive mapping tool you can explore the province’s EDI data for all five EDI scales over multiple waves (combined years of data). HELP's interactive map illustrates the results of the Early Development Instrument at three different geographical levels:

Education: Explore EDI data for each of BC’s 59 School Districts.

Health: Explore EDI data for all of BC’s five geographical Health Authorities by Local Health Areas (LHAs). 

Community: Explore EDI data for each of HELP’s 289 individual Neighbourhoods. A street-level zoom feature clearly delineates neighbourhood boundaries.

Explore Meaningful Change Over Time

Collecting EDI data over multiple years allows us to explore trends in children’s development and to answer the broader question: “Are our Kindergarten-aged children doing better, worse or about the same as in the past?” With each new wave of EDI data, vulnerability rates change across the province. While some neighbourhoods see improvements over time for particular aspects of children’s developmental health, others see declines. When looking at all of these changes over time we need to identify the amount of change in vulnerability that is large enough to be meaningful – and therefore a focus of further exploration and discussion.

HELP's interactive Critical Difference Tool allows you to explore the meaningful change in vulnerability rates within a school district, between neighbourhoods and between two points in time. To find out how data changes over time in your region visit an individual School District page.
