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.
The Norwegian Kindergarten Authority
The OIS Kindergarten/Reception division is approved by the Norwegian Kindergarten Authority. This implies that OIS has to comply with all the provisions in the Norwegian kindergarten regulations. The school receives public financial support for the Kindergarten program.
