Comparing schools on a single feature is useless: the most expensive is not the best, and a famous name says nothing about what is backed by documents. The score is therefore built from nine criteria with different weights - from academic programmes and accreditation to facilities, clubs and fees relative to other schools in the country.
A criterion counts towards the score only when there is verifiable data behind it. That is why every score says how many of the nine criteria were counted: at schools in Waterloo that is 7.7 out of 9 on average. A school with a detailed site and a school with no site cannot earn an equally reliable score, and that is shown rather than hidden.
Ratings and reviews from Google Maps and other map services are not used: their terms forbid aggregation. Only verified reviews left here count. Full methodology →
