Early Development Instrument (EDI)

In March 2006, a school readiness survey called the Early Development Instrument was completed by 86 grade Primary teachers throughout the Annapolis Valley Regional School Board. Each Primary teacher completed a survey on each of his/her grade students. In total 1,007 surveys were completed.

Collecting data from the EDI is part of the overall research of UEY Western Nova Scotia. The EDI is a population based measure of school readiness intended for communities, making it an ideal research tool for the UEY Western Nova Scotia initiative.

What is a Population based measure?

The survey is not a clinical assessment; it is a teacher completed assessment of a child's readiness to begin school. The results do not reflect any one child. Rather the data is reported by a population of children at the community level, as shown by the maps below. 

The EDI was created by researchers at the Offord Centre for Child Development located at McMaster University. For further information on the EDI click the link below:

The EDI measures school readiness based on the following five developmental domains:

Explanation of the data:

Below are links to maps displaying the results of the 2005/06 EDI for UEY Western Nova Scotia.

You will notice a pie chart over a specific research area. These charts display the percentages of children in that area scoring Very Ready (Green), Ready (Yellow), At Risk (Orange) and Vulnerable (Red) with respect to school readiness.

Very Ready - Children scoring in the top 25th percentile
Ready - Children scoring between the 25th and 75th percentile
At Risk - Children scoring between the 25th and 11th percentile
Vulnerable - Children scoring below the 10th percentile
