Oslo International School (OIS) is a coeducational, English-language, day school enrolling students ages 3 to 18 years. The school was established in 1963. Approximately 60 percent of its students are from international businesses and embassies in the Oslo area. The school year extends from mid-August to mid-June. Admission to OIS is open to students of all nationalities who demonstrate the ability to access and benefit from the challenging international curriculum and program offered by the school. OIS aspires to develop students who will attain, to the best of each individual’s ability, high levels of understanding and competencies across a broad range of subjects and will attain the essential knowledge, skills, and attitudes to be life-long learners who are active in their own learning to become ethical international citizens of a changing and challenging world.

Organization: OIS is an independent, nonprofit educational trust under Norwegian legal jurisdiction. It is administered by a managing director and 2 heads of school, while a Board of Trustees has responsibility for the financial status and strategic direction. Board membership is by appointment. It is currently composed of representatives from an embassy, 6 businesses and private citizens as well as 2 school employees. Most members are parents at the school.

Community Activities Manager is a full-time resource that is dedicated to facilitating the transition to Norway of both students and families. This person is responsible for the family benefit program (covering settling in support, volunteering and networking opportunities, and a wide range of activities) and a comprehensive student after-school program.

Curriculum: As of August 2019, the school is organized into 2 separate divisions, preschool and primary (from age of 3 to Year 6) and secondary (Year 7 to IB2 Diploma). Class sizes are small, usually less than 18, providing for valuable individual attention to student needs. Support teachers (ELL and SfL) are available for students acquiring English language proficiency or in need of academic assistance. Many extracurricular activities and sports are offered after school hours. An active Parents’ Association (OISPA) provides a range of services and activities for the school as well. The primary school teaches mathematics, literacy, music, art, drama, information communication technology (ICT), and Norwegian as “stand alone” subjects; other subjects are taught through the International Primary Curriculum, a program that integrates social studies and science with an international focus for each unit of study. Specialist teachers are utilized for physical education, music, art, ICT, and Norwegian instruction. The secondary school is organized into 2 sections, lower secondary (Year 7-10), and upper secondary (Pre-IB through IB2–International Baccalaureate). The lower secondary follows a comprehensive academic program aligned with the philosophy and aims of the International Baccalaureate Program. The upper secondary offers the International Baccalaureate Diploma Program. In 2010 OIS received a full 10-year school reaccreditation by the Council of International Schools (CIS) and the New England Association of Schools and Colleges (NEASC) as well as a successful 5-year program evaluation through the International Baccalaureate Organization (IBO), which was also awarded in 2015. All graduates successfully pursue post-secondary education with many earning admission to some of the most prestigious colleges and universities in the world.
