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.
AEAM survey measures · Fall 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.

This letter in context
Letters held by the 20 CBE elementary schools closest to this school on the two figures below (not on ratings, and not necessarily nearby):
- 1 rated A+ (Very strong)
- 7 rated A (Strong)
- 5 rated B (Solid)
- 1 rated C (Fair)
- 0 rated D (Developing)
- 6 not yet rated
Across CBE elementary schools, these two figures line up with about 45% of the differences in Roost Ratings between schools. The rest is not explained by them.
Based on the 2021 Census: the share of children in low-income households (2020 incomes) and the share of adults aged 25 to 64 with no certificate, diploma or degree, for the people living in each school's designated area (its catchment). That describes who lives nearby, not who enrols, and the two can differ.
Context only: it does not change Sunalta School's letter.

Context
Classes and enrolment
Typical class size
- K to Grade 3
- 20Typical for these grades across CBE schools: 22from 9 classes
- Grades 4 to 6
- 25Typical for these grades across CBE schools: 25from 7 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.
Students enrolled

- 2025/26: 369 students
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.
