About the fees Annual tuition for 2026-2027 paid by families themselves on top of the municipal skolpeng subsidy: EY3-EY4 and Kindergarten 190500 SEK, grades 1-5 135000 SEK, grades 6-9 152000 SEK, grade 10 179000 SEK, grades 11-12 191500 SEK. Skolpeng is usually available for students registered in the municipality with a Swedish Personal Number: in grades 1-9 if they meet admission requirements, in grades 10-12 where approved by the municipality; 'In grades 10-12, non-EU diplomatic families are generally not eligible'. Without the subsidy, families pay its amount on top of the listed fee, and the total, according to the school, is significantly higher. Fees include lunch, an iPad or laptop, curriculum trips, learning support and EAL. Fees are paid yearly in advance in two equal instalments, usually in April and November; students joining in the second term pay 50%; fees are not reduced or refunded for late entry, absence or withdrawal.

Applications are reviewed against these criteria with sibling priority and by application date; applications are accepted all year. English requirements: any level up to grade 5 and in grades 6-8 (an intensive course may be recommended in 6-8), about B1/B1+ in grade 9, about B1+/B2 in grade 10, B2 in grade 11 with an EAL assessment; students coming from the MYP need a Personal Project grade of at least 4 and at least 32 points in MYP 5. Steps: online application, 3000 SEK fee, documents (passports, immunisation records, three years of transcripts in English, a teacher recommendation, specialist reports for special needs), Admissions Committee decision; an offer must be accepted within 10 working days. If no place is available, the child is waitlisted. The school reserves the right to decline admission if it cannot provide the support required.

IBInternational Baccalaureate
A Swiss non-profit, working since 1968. Its programmes are among the most widely recognised school programmes in the world. Authorisation is granted stage by stage, so a school with the final stage does not necessarily run the younger ones; which stages this school holds is set out in the line below.
What the badge means for this school. The school is allowed to run this programme and to award its certificate. This is a confirmation of the programme, not a judgement on the school as a whole. The entry stands in the organisation's public register - anyone can check it. At this school: PYP (ages 3-12), MYP (ages 11-16), DP (ages 16-19). PYP is the primary stage, ages 3 to 12. It is not a set of subjects but a frame for the whole school: learning is built around lines of inquiry, and there are no exams at the end. MYP is the middle stage, ages 11 to 16. There are no exams here either; at the end an optional electronic assessment of pupils' work is possible. DP is the final stage, ages 16 to 19: six subjects plus a compulsory core of theory of knowledge, an extended essay and CAS. The diploma is accepted by universities all over the world, and in a number of countries it counts for admission on the same footing as the local leaving certificate.

Reviews
No reviews yet. The community rating counts towards the score once a school has five verified reviews - until then we do not show a zero, so as not to mislead.

A low score here means the school does not write about this, not that the school does not have it: a school with good security and a sparse site will score low. A school can fill in its profile, and the score will be counted again.
The score is counted from 8 of the 9 criteria.Only those with checkable data count: programmes and accreditations from official registers, the fee from a published price list. Where it says "scored on the median", the school has no data and the middle of the list is put in its place, so that a gap gives no advantage. Admissions, teaching staff and reviews come in as their data arrives.
