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.
