The ranking holds 2 schools with an international accreditation or an authorised programme.
We do not take reviews from maps and directories: their terms forbid it, and nobody checks the quality there. Everything below comes from the official registers of the accrediting organisations and from the schools' own sites, and every fact carries its source and the date of the check.
All 2 schools in the ranking are private. We have not yet found a state school in Río Grande with an international accreditation. 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.
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 Río Grande that is 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, Yandex Maps and 2GIS are not used: their terms forbid aggregation. Only verified reviews left here count. Full methodology →
Escuela del Cono Sur comes first with 60.7 points out of 100, counted from 7 of the 9 criteria. Next comes Colegio Integral de Educacion Rio Grande (CIERG) (60.7). The score is built from data anyone can check: accreditations found in official registers, programmes, facilities and published fees. A place in the ranking is not for sale.
The ranking holds 2 schools: 2 private. We found no state school in Río Grande with an international accreditation. Private and state schools go into the ranking on equal terms.
The score of every school adds up from nine criteria with different weights: academic programmes, accreditation, facilities, clubs, the fee against other schools in the country, reviews, university destinations, safety and teachers. A criterion counts only when there is data behind it that can be checked, so every score says how many of the nine were counted. Right now that is 7 out of 9 on average. We do not use reviews from maps or directories.
