Earning Your OSSD

Diploma Requirements And Granting of Equivalency Credits

To obtain an Ontario Secondary School Diploma (O.S.S.D.), a student needs to earn 30 credits including certain compulsory credits. A credit is earned by attending 90 hours of instruction and obtaining a mark of at least 50% on work completed in the course. PLEASE NOTE: To be successful in subsequent courses or higher education, a mark of 70% is often needed, so students should work toward grades higher than 50%.
Adults are eligible for equivalency credits through the Prior Learning and Equivalency Process (PLAR). PLAR applications must be submitted 1 month prior to the end of the quad. Applications cannot be processed for students not enrolled at Yorkdale.
Students can apply for the PLAR process only after having successfully completing 2 quads at Yorkdale, have studied 4 courses at the senior level (grade 11 or 12).
