3 of the 4 schools in the ranking are private. The other 1 is a state school, set out below. The type of school does not affect the score: private and state schools sit in one list and are scored by the same formula, and only verifiable data moves the number.
1 school with an international accreditation is funded by the state: IES Plurilingüe Rosalía de Castro. Admission to these schools is usually competitive, and tuition is free or markedly cheaper than at a private school. In the ranking they stand alongside private schools and are scored on the same nine criteria.
Schools in Santiago de Compostela with an IB programme (1): IES Plurilingüe Rosalía de Castro. Authorisation is confirmed against the International Baccalaureate register.
A facility counts only when the school names it outright on its own site: a modern campus is not a swimming pool. Swimming pool: 1 school · Boarding: 1 school.
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 Santiago de Compostela that is 7.3 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, Yandex Maps and 2GIS are not used: their terms forbid aggregation. Only verified reviews left here count. Full methodology →
