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.

Context

This letter in context

Letters held by the 20 ECSD elementary schools closest to this school on the two figures below (not on ratings, and not necessarily nearby):

  • 0 rated A+ (Very strong)
  • 2 rated A (Strong)
  • 2 rated B (Solid)
  • 11 rated C (Fair)
  • 5 rated D (Developing)

Across ECSD elementary schools, these two figures line up with about 40% 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 St. Leo Catholic Elementary School's letter.

Classes and enrolment

Typical class size

K to Grade 3
18Typical for these grades across ECSD schools: 23from 6 classes
Grades 4 to 6
26Typical for these grades across ECSD schools: 26from 3 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 ECSD figure is the middle of every ECSD school's own figure for those grades, across Alberta's release.

Students enrolled

191 students in 2025/26 (preliminary)

Students enrolled each school year, 2016/17 to 2025/26

  • 2016/17: 194 students
  • 2017/18: 202 students
  • 2018/19: 198 students
  • 2019/20: 192 students
  • 2020/21: 169 students
  • 2021/22: 158 students
  • 2022/23: 153 students
  • 2023/24: 141 students
  • 2024/25: 171 students
  • 2025/26: 191 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.
