Classes and enrolment
Typical class size
- Grades 7 to 9
- 30Typical for these grades across EPSB schools: 28from 382 classesNot counted above: 2 classes with fewer than 10 students (Alberta does not publish their sizes).
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.

EPSB schools are assigned by home address. Londonderry is the designated junior high only if your address falls inside its catchment — confirm yours with an address lookup. 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.
