Classes and enrolment
Typical class size
- Grades 10 to 12
- 35Typical for these grades across CBE schools: 31from 234 classesNot counted above: 1 class with fewer than 10 students (Alberta does not publish its size).
Each figure is the middle class size in those grades for 2025/26, among the classes whose sizes are published. A class is one teacher with one group of students, so a group with several teachers counts once per teacher, and in junior and senior high each course section counts. The CBE figure is the middle of every CBE school's own figure for those grades, across Alberta's release.
