The methodology
The data behind this score

Classes and enrolment
Typical class size
- Grades 10 to 12
- 32Typical for these grades across EPSB schools: 31from 326 classes
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 EPSB figure is the middle of every EPSB school's own figure for those grades, across Alberta's release.

Alternative programs are programs of choice — you apply directly to a school that offers them, and spaces can be limited; they are not guaranteed by address.
