The ranking holds 4 schools with an international accreditation or an authorised programme. International Baccalaureate programmes are taught at 3 of them. The British Cambridge route, IGCSE and A-Level, at 1. A year of school costs from $1 039 to $3 879.
2 schools publish a monthly fee rather than a yearly one and do not say how many payments they charge over a school year. We count such a year as ten payments: that is the number charged by the schools that do state it, and that is how long the school year runs in most countries of the ranking.
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.
| Cheapest | $1 039 a year | Fagerhaug International School |
| Median | $1 039 a year | top of the fee range at 2 schools with a published fee |
| Most expensive | $3 879 a year | Birralee International School Trondheim |
| Free | 1 school | Trondheim Katedralskole |
Figures are converted to dollars at a weekly rate; schools publish their fees in their own currency. One-off charges, meals, transport and uniform are not included unless the school says otherwise. Fees for schools in Trondheim are taken from published price lists, not from what third parties say.
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 in Trondheim teaches an international programme with no tuition fee: Trondheim Katedralskole. On value for money such schools get the top score, because they sit outside the price range altogether.
1 school with an international accreditation is funded by the state: Trondheim Katedralskole. 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 Trondheim with an IB programme (3): Trondheim Katedralskole, Trondheim International School, Fagerhaug International School. Authorisation is confirmed against the International Baccalaureate register.
The British Cambridge programme - IGCSE and A-Level - is taught at 1 school in Trondheim: Birralee International School Trondheim.
These schools stand in the suburbs, up to 30 km from the centre of Trondheim. Each card names the school's own town; they are gathered here because a family in Trondheim chooses between them as between districts of one place.
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 Trondheim that is 7.8 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 →

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.

We do not use reviews from maps or directories.
