The methodology

The data behind this score

The Roost Rating weights AEAM above PAT, plus Roost field research, capped at 95. A missing source has its weight shared across the ones that remain, never counted as a zero. This school got 62.5% survey · 37.5% exams.

This rating comes from two independent sources: how this school’s Grade 6 students did on Alberta’s provincial exams, and the AEAM survey of parents, students, and teachers.

Fraser (not scored)

1.2/10Shown for comparison, but it does not affect the Roost Rating. Half of it is the average exam mark we already read ourselves, so scoring it would count one set of exams twice: why.

AEAM survey measures · Spring 2025

Each parent, student, and teacher survey measure beside the Alberta average. The verdict is Alberta Education’s own evaluation — it weighs the school’s achievement band and its own trend, so a measure can sit below the Alberta number without a concern or issue flag, or carry one while above it.

Context

Classes and enrolment

Typical class size

K to Grade 3: 21.5Typical for these grades across EPSB schools: 23from 32 classes
Grades 4 to 6: 25Typical for these grades across EPSB schools: 25.5from 23 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.

Students enrolled

482 students in 2025/26 (preliminary)

Enrolment moves with boundary changes, new schools nearby, the grades a school offers and how many children live close by. Most schools here had fewer students in 2020/21, the first school year of the pandemic.

Context only: these describe the school's situation, not how well it teaches, and neither is part of the Roost Rating.
