Developmental Health of Senior Kindergarten Students

The Early Development Instrument is used across Ontario to measure the developmental health and wellbeing of senior kindergarten children.

In Niagara, the percentage of children who are considered vulnerable on one or more domains provides the data to inform the Early Development Risk Factor portion of the Community dial for Council's Strategic Priorities.

Early Development Instrument

In the second half of the school year, senior kindergarten teachers complete a questionnaire for each senior kindergarten child in their class. This questionnaire measures developmental health and wellbeing in five general domains:

  1. Physical health and well-being
  2. Social competence
  3. Emotional maturity
  4. Language and cognitive development
  5. Communication and general knowledge

Scores are calculated to determine the "vulnerability" of children in each domain. A child is considered vulnerable if they score below the 10th percentile in a particular domain.

The results reflect children's experiences before entering school and tell us about the supports provided or needed within a particular community, region, municipality or neighbourhood.

Since the Early Development Instrument has been implemented four times over the past 10 years in Niagara, it has allowed us to monitor the developmental health and wellbeing of senior kindergarten children over time.

The charts below summarize the most recent results and compare to other years and to the province. In order to maintain comparability with the provincial averages, children who had identified special needs (diagnosis) were not included in this analysis. Data for children with special needs is available upon request.
