Oslo is one of the easier European postings for English-speaking families: short winters in the family-life calendar, generous parental leave culture, and a small but capable cluster of bilingual and international schools. The choice often comes down to a single question — how much Norwegian do you want your child to learn, and how fast?
This 2026 guide focuses on bilingual Norwegian-English schools in Oslo: how they actually teach, what the fees look like in Norwegian kroner, and how to choose based on your family's plan.
How bilingual schooling works in Oslo
Norway's public school system is high quality and free, with English taught from Year 1. Many expat families start there and add private English tutoring. But for families on shorter assignments or those who want their child to remain on an international qualification track, Oslo's bilingual and international schools are the practical choice. They split roughly into three categories:
- True bilingual immersion: Two-language teaching from kindergarten, with content subjects split between Norwegian and English by year group or subject.
- English-medium international: English as the primary teaching language, Norwegian taught daily as a second language.
- Heritage-language community schools: French, German, Japanese — useful for families on specific postings.

2026 fees in Norwegian kroner
Norway's bilingual and international schools are less expensive than equivalents in London or Switzerland, but the cost of living offsets some of that. Indicative annual tuition for 2026:
- Early Years (ages 3–5): NOK 95,000 – 165,000
- Primary (Year 1–6): NOK 145,000 – 220,000
- Lower Secondary (Year 7–9): NOK 175,000 – 240,000
- Upper Secondary / IB Diploma / IGCSE: NOK 210,000 – 280,000
Enrolment fees range from NOK 5,000 to NOK 15,000 and are usually non-refundable. Lunch is typically not included, and school transport in Oslo is often arranged separately via Ruter (the public transport authority) for student passes.
Which bilingual model fits your child
- Short stay (1–2 years), returning home: Lean toward The British School of Oslo or Oslo International School's IB pathway. The child stays on an internationally portable qualification.
- Medium stay (3–5 years): True bilingual immersion at Asker International or DNS can build durable Norwegian alongside English.
- Long stay or permanent move: Consider transitioning to a Norwegian public or private school after a year at an international school for Norwegian acclimatisation, especially for younger children.
- Child with no Norwegian background: Look for explicit NAL (Norwegian as an Additional Language) provision in the first year, ideally with small-group withdrawal classes.
Admissions tips for Oslo bilingual schools
- Apply 6–9 months in advance for OIS and The British School of Oslo. Smaller schools accept rolling applications.
- Norwegian schools require apostilled birth certificates and prior academic transcripts, with sworn Norwegian or English translation.
- The Norwegian school year starts in mid-August. Plan visa and housing accordingly — Oslo housing tightens dramatically in July and August.
- Ask the school how Norwegian is taught: hours per week, group size, and whether progress is reported separately from other subjects.
- Confirm how the school manages the transition into either the Norwegian system (folkehøgskole, videregående) or international universities at upper secondary.
Norwegian public school as the bilingual alternative
One option many expat families overlook: enrolling at a strong local Norwegian public school with private English tutoring on the side. Public schools in central and west Oslo (Bygdøy, Frogner, Ullern) have excellent academic standards and a structured English curriculum. The trade-off is that academic content is delivered in Norwegian, so this works best for younger children or those staying longer than 3 years. For school-aged children with no Norwegian, a one-year transition at an international school often eases the move.
Frequently asked questions
Are bilingual schools in Oslo expensive compared with London?
Tuition at top Oslo bilingual schools runs roughly 30 to 40 percent below comparable London international schools in EUR-equivalent terms. Norway's higher cost of living, especially housing in central Oslo, offsets some of that saving.
Will my child be fluent in Norwegian after a bilingual school?
It depends on years of exposure and starting age. Children who start true bilingual immersion at age 3–5 typically reach conversational fluency by Year 3 and academic fluency by Year 6. Older starters (Year 7+) usually leave with strong conversational Norwegian but rarely full academic mastery.
Can my child move from a bilingual school into the Norwegian public system?
Yes, and many do. Bilingual schools usually have a structured transition pathway, but timing matters — moving in Year 4 or Year 5 is generally smoother than Year 8 or 9. Speak to both the international school and the receiving Norwegian school before deciding.
