Three municipal schools in Oslo also offer the International Baccalaureate programme in English, so if you're lucky enough to get a place, you can get an international schooling for your children for free. For most schools, the deadline for applying is April 1st if you want your child to start at the start of the school year in August, although if you missed this date or are arriving in Norway in the middle of the school year, it may be possible to squeeze a child in if you contact the school directly. If you look at the schools offering International Baccalaureate, only Oslo International School made the top 100 schools worldwide in the annual ranking put together by Education Advisors, sharing 55th place with 3 other schools.
