Wave

Introduction

The Early Development Instrument (EDI) data provide insights about the whole child, including their physical, emotional, social, and cognitive development in kindergarten, and how children’s developmental health changes over time and across the province.

The EDI was the first questionnaire implemented by the Human Early Learning Partnership. All BC school districts and some independent and First Nations schools have participated in EDI data collection over the last two decades.

The EDI Data Dashboard is an online interactive tool for exploring trends in EDI data from the first publicly reported wave of data (Wave 2, data collected 2004–2007), to the most recent (Wave 8, collected 2019–2022). EDI data are collected on a “wave” schedule, spanning 2-4 years, to ensure sufficient data are gathered in all school districts involved. The data reported through the Dashboard are based on children’s home postal codes and include kindergarten children who live within the boundary type selected. See the chart on the right for a breakdown of EDI waves and years of data collection.

EDI QUICK FACTS
  • Questionnaire completed by kindergarten teachers for children in their classrooms in February of the school year
  • EDI data are collected in 2-4 year periods known as waves and are based on the school calendar from September to June.
