The Objectives of De-Streaming 

De-streaming is the phasing out of Grade 9 and 10 Academic and Applied (streamed) courses. Research shows that students benefit from learning with students of varied abilities and interests and in settings where teachers have appropriate expectations for all students and believe that all students can be successful.

Remove barriers and support more students to graduate from secondary school and pursue post-secondary education pathways of the choice.

The Ontario Ministry of Education’s Creating Pathways to Success document grounds our belief that: all students can be successful, success comes in many forms and there are many pathways to success.
