WCDSB Middle Years Development Instrument (MDI) Survey
We will administer the Middle Years Development Instrument (MDI) for students, from Grade 4 through Grade 8, between February 22nd and March 11th. The MDI is an anonymous and voluntary online survey and
will take place during class time on a board provided device with their classroom teacher. The MDI survey
asks students about their thoughts, feelings, and experiences in school and in the community related to five
areas of development that are strongly linked to well-being, health, and academic achievement: Physical
Health & Well-Being, Connectedness, Social & Emotional Development, School Experiences, and Use of After School Time.
Any student may choose not to participate, to stop participating, or to skip a question at any time.
Additionally, parents/guardians who would like their child to be exempted from participating in the MDI may request an exemption at any time before February 17, 2022. Please see this link for more information and opting out:
