Oslo is not “the international school.” It is a Norwegian capital whose public grunnskole is allowed to be first, plus three official fee-paying climates posting families name in the first week: an English IB campus west of the city, a French lycée in the centre, and a German-Norwegian house on the river.
The portraits we have are Oslo International School in Bekkestua, Lycée français René Cassin on Skovveien and Vulkan, and Deutsch-Norwegische Schule Oslo at Myra. Use them for kroner tables and admissions rules. OIS prints a 2026–27 Board PDF. LFO prints local and company rates. DENOSO prints monthly makspris. This note is the city between them. The Norway country page is the wider map — Stavanger, Bergen, Trondheim’s Birralee, Sandefjord, the UWC in the fjord.
Three climates, one dark morning
OIS sits on Gamle Ringeriksvei in Bekkestua, in Bærum, not on Karl Johans gate. English in class. Norwegian for Years 1–10. IB in the diploma years. A fee-funded campus the school describes without a state-subsidy story. Time the west-side commute on ice.
LFO sits in the centre. Skovveien 9 for much of collège; Vulkan 11 for lycée; 3e on both lists. French national week. Baccalauréat, not IB. Maternelle follows Oslo makspris. From CP the language test is real, and the company rate is automatic unless you can prove there is no employer cover. Time Frogner, then Vulkan.
DENOSO sits at Myra 3 in Sagene, in the park by the Akerselva. German plans, Norwegian in Norwegian and Samfunnsfag. DIA and Vitnemål after 12. Monthly school fees, July free, no school bus. Time Torshov, not Bekkestua.
They share a capital and almost no Monday. Walk at least two, then the municipal school your address already names.
The public yard is the other school
If you might stay, an English diploma is not automatically the kindest paper. A kommune grunnskole, a friskole with a Christian or Steiner thread, a videregående that still owns the mountain — those are official mornings. Families looking at OIS often also walk the municipal door, because the next five years may still be Norwegian.
The language of the yard is the test that matters more than the IB page. A child can thrive in English at 9 a.m. and still be lonely at 11 if the tram is speaking Norwegian — or lonely in French if the park is not.
Bergen and Stavanger are not suburbs of Oslo. Do not flatten Norway into one Bærum driveway.
What to ask on the stairs
Ask which paper this child will hold — IB, Bac, DIA and Vitnemål, or a municipal path. Ask LFO whether the invoice is local or company. Ask DENOSO what AKS costs after the municipal core-hours decision. Ask OIS how much Norwegian a shy eleven-year-old really has by the second spring.
Time Bekkestua, Skovveien and Myra on the same dark Tuesday.
The city hub is the short map. The three portraits are the long ones.
