The Ontario Secondary School Diploma (OSSD) is a diploma granted to secondary school graduates in the Canadian province of Ontario. It is part of the publicly funded province-wide school system. It is awarded to all students who complete the Ontario education curriculum, including students in Special Education, the TOPS program, MaCS program, IB Program, and other focused secondary school programs.
Adults who did not complete an Ontario Secondary School Diploma may take the Canadian Adult Education Credential battery of high school equivalency tests to receive an Ontario High School Equivalency Certificate.[1]
You need a score of 55% on each of the 5 tests to pass the CAEC and get an Ontario High School Equivalency Certificate.
