[School readiness survey of Montreal children starting school].

The aim of the survey was to provide a picture of the school readiness of 5-year-old Montréal children starting school and to identify disparities between neighbourhoods and the socio-economic factors determining these differences. 10,513 children were assessed using the Early Development Instrument. The results show that in Montréal, one child in three is vulnerable in at least one area of school readiness.
