CIS and NEASC Accreditation
OIS is accredited by both CIS and NEASC. Accreditation is a process by which a school seeks approval/validation from an outside agency. There are many organisations which offer to evaluate and accredit schools. The process varies from agency to agency. The purpose of the CIS/NEASC programme is to provide a professionally sound scheme of self-evaluation and independent inspection, particularly for international schools. Involvement in the program provides a valuable stimulus for schools to think more deeply about their situation and opportunities, and to plan for improvements. Once accredited, the school is locked into a process of regular reviews to ensure continued quality assurance. After undertaking a comprehensive review, OIS was first accredited in Autumn 2005. In December 2010 the school was awarded a full ten year reaccreditation by CIS and NEASC.
International Baccalaureate Organization (IBO)
The two last years of the Upper Secondary School at OIS are accredited by the International Baccalaureate Organization . The IBO is a non-profit educational foundation, motivated by its mission, focused on the student. The program for students help develop the intellectual, personal, emotional and social skills to live, learn and work in a rapidly globalizing world. Founded in 1968, IBO currently works with 3,659 schools in 146 countries to develop and offer four challenging programs to over 1,131,000 students aged 3 to 19 years.
The Norwegian Educational Authority
OIS is approved by the Norwegian Educational Authority as an Educational Act §2-12 school since 2004. This implies that OIS has to comply with a limited number of provisions in the Norwegian educational regulations. The school is, however, exempted from a detailed regulation of areas such as the curriculum, admission policy and tuition levels. The school receives only a limited funding for the obligatory Norwegian language and culture program.
