Secondary Program (Grades 9-12)

Our Secondary Program (Grades 9–12) prepares students for success in university, college, and life. The curriculum emphasizes core academic areas such as Math, English, Science, Business, Accounting, Social Science, the Arts, and Computer Technology. As students progress through the grades, they can begin to focus on subjects that match their strengths and career interests.
​
Unlike many local schools, Trillium does not require students to write standardized exams like CXC, CSEC, or A-Levels. Instead, students earn the Ontario Secondary School Diploma (OSSD)—a globally recognized qualification that allows for direct entry into universities and colleges in Canada, the U.S., the Caribbean, and Trinidad and Tobago.
