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.

This letter in context
Letters held by the 20 CCSD elementary schools closest to this school on the two figures below (not on ratings, and not necessarily nearby):
- 2 rated A+ (Very strong)
- 4 rated A (Strong)
- 9 rated B (Solid)
- 4 rated C (Fair)
- 1 rated D (Developing)
Across CCSD elementary schools, these two figures line up with about 30% 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 Don Bosco School's letter.

Classes and enrolment
Typical class size
- K to Grade 3
- 26Typical for these grades across CCSD schools: 24.5from 32 classes
- Grades 4 to 6
- 26Typical for these grades across CCSD schools: 27.8from 36 classes
- Grades 7 to 9
- 18Typical for these grades across CCSD schools: 26.8from 37 classesNot counted above: 6 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 CCSD figure is the middle of every CCSD school's own figure for those grades, across Alberta's release.
