Oslo International School (OIS) is a fully accredited independent international day school for students from 3 to 19 years of age (Pre-School to IB Diploma). The school is a not-for-profit education trust with an enrolment of around 600 students.  We are located in modern, architecturally unique facilities in a green suburban neighborhood close to  a public transportation hub.

OIS was founded in 1963 to serve the educational needs of children from diplomatic and international business families temporarily residing in the greater Oslo area.  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.

The school is organized into two separate divisions, Primary (Kindergarten to Year 6) and Secondary (Year 7 to IB Diploma). Classes/teaching groups average 18 or fewer students providing for valuable individual attention to student needs. Support teachers (EAL and Special Education) are available for students acquiring English language proficiency or in need of academic assistance.   A number of extra-curricular activities and sports are offered after school hours. The school year runs from mid August to mid June.  Our international staff come from 21 different countries.

OIS serves globally-mobile and internationally-minded families representing 48 countries. Approximately 56% of our students are expats from international or local business families and 12% come from the diplomatic community. The remaining 32% are Norwegian. Among the total student population 65% are European, 15% North American, 15% Asian, 2% Australian, and about 1% each come from the Middle Eastern, Africa and Latin America.  About 73% of our students speak English as an additional language.

Our school is committed to developing the unique potential of every student while instilling the core values of respect, cooperation, caring, and challenge.

We aspire 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.
  • Attain the essential knowledge, skills and attitudes to be life-long learners.
  • Be independent learners, active in their approach to their own learning.
  • Be ethical international citizens of a changing and challenging world.

“OIS has students that are welcoming, teachers that are motivated and care about their students, small class sizes, and challenging academics.”
