We take full advantage of Ontario’s secondary education system to offer courses on a semester and credit basis. Students need a minimum of 30 credits to complete their high school education and earn an Ontario Secondary School Diploma (OSSD). Columbia recognizes and awards credits for successfully completed high school courses taken in the students’ home country.

Thus, students only have to complete the remaining courses needed to meet the outstanding credits. 这个信用体系, coupled with our semester programming, allows international students to pace their studies according to their academic ability and to take courses that match their personal interests.
