De-streamed grade 9 mathematics course begins in September 2021

De-streaming: What is it?

In streamed education systems, students select between applied and academic courses in Grades 9 & 10. Based on prerequisite mapping, applied courses typically take students on a pathway that leads to college or apprenticeships, while academic courses lead students on a pathway to university.

De-streaming removes the set pathways from Grade 9 & 10 courses, allowing students to make pathway decisions later in their secondary education years. De-streaming of courses provides more equitable education for all students to succeed, thrive and reach their full potential.

What is changing?
In September 2021, Ontario secondary schools will begin de-streaming courses starting with grade 9 mathematics (MTH 1W).

What to expect:
• Beginning September 2021, a new de-streamed grade 9 mathematics curriculum will be rolled out across all Ontario secondary schools
• Locally developed mathematics courses will continue to be offered
• The HWCDSB will continue to offer a mathematics preparation course for students who would benefit from extra math support, both during the summer and school year
• De-streaming in other subject areas is expected to follow
