Your Guide to OSSD Requirements & OSSD Diploma Details
Before the rise of online high school courses in Ontario, students typically had to attend traditional, brick-and-mortar secondary institutions to get their diplomas. Excluding those who attended in-person private schools, students had no choice but to attend public schools within their particular geographical regions—that is, within their “boundary maps.”
These students often had few public schools to choose from, especially those who lived in underpopulated and rural areas. Students living in wealthier boundary maps tended to have access to public secondary schools with more funding, resources, and one-on-one attention, as well as higher retention and graduation rates.
