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 is rated entirely on exams.
This rating comes from one test: how this school’s Grade 6 students did on Alberta’s provincial exams. We have no survey of parents, students, and teachers for this school, and its absence does not count against the score. A test-only rating does track neighbourhood income more closely than one with survey results behind it, so ask the school what the exams do not show.

Classes and enrolment
Typical class size
- Grades 4 to 6
- 25Typical for these grades across CBE schools: 25from 35 classes
- Grades 7 to 9
- 30Typical for these grades across CBE schools: 28from 115 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 CBE figure is the middle of every CBE school's own figure for those grades, across Alberta's release.

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.
