Alberta Diploma Examinations are standardized provincial exams written by students completing certain Grade 12 courses. These exams count for 30% of the final mark in subjects including English, Social Studies, Mathematics, Biology, Chemistry, and Physics. The exams ensure consistent academic standards across all Alberta high schools and provide universities with comparable measures for admission decisions. Diploma exams are administered province-wide on set dates, with accommodations available for students with documented needs. Results appear on official transcripts and influence post-secondary acceptance.
