The annual results and participation rates for diploma examinations administered to students in Alberta schools. Diploma results and participation rates are aggregated into separate reports for the following levels: provincial, school authority, and school. Data elements are suppressed (represented as N/A) if fewer than six students are included in the calculation. The diploma exam results data includes the number of students writing, the percentage of students achieving the standard of excellence and the acceptable standard, the average percentage mark, and basic statistical attributes. These elements are included for both the school-awarded and the diploma exam marks for diploma courses in each of the past five school years. The diploma exam participation rates data includes the number of students in a cohort that is completing their third year of high school based on the school year they entered grade 10, the number of students in that cohort that participated in each of the diploma exams, and the participation rate (the ratio of two) for each of the past five school years.
