This bulletin contains general information about the Grade 12 Diploma Examinations Program in Alberta, Canada. All twelfth graders must write at least one diploma examination to receive a high school diploma. The examination certifies academic achievement in English 30 and 33, Social Studies 30, Mathematics 30, Biology 30, Chemistry 30, Physics 30, and Langue et Litterature 30. To obtain credit in any high school course, students must earn a final mark of at least 50 percent.
