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.
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.

Classes and enrolment
Typical class size
- K to Grade 3
- 19Typical for these grades across CBE schools: 22from 11 classes
- Grades 4 to 6
- 26Typical for these grades across CBE schools: 25from 6 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.

CBE schools are assigned by home address. W. O. Mitchell School is the designated elementary only if your address falls inside its catchment — confirm yours with an address lookup. Alternative programs are application-based and many run an admission lottery — they are not guaranteed by address. See how and when applications work.
- Before & after care
From W. O. Mitchell School's own page “A before and after school care program will be offered by Summit Kids, a third-party operator, in our school.”
“At WO Mitchell School, given our bilingual focus, students engage with two languages, English and Spanish, in fluid and dynamic ways.”
From the school's own CBE page — care arrangements and class placements change; confirm with the school before you decide.
Register through the Calgary Board of Education.
