Trondheim International School (ThIS) was founded in Trondheim on 28 April 2004 by Linda Kollien, Hasle Gjerde, Ole-Petter Krabberød and Natasha Amberg. Since 2008 Trondheim International School has been an IB World School.
ThIS offers programmes for children from grade 1 to grade 10 (6 –16 year old). ThIS is an authorized school for the prestigious International Baccalaureate (IB) programme administered by the IB organisation. Our school offers both the Primary Years Programme (PYP) and MYP (Middle Years Program).This believes that there should be a comprehensive IB education in Trondheim, including the Primary Years program, the Middle Years Program and the Diploma Program (offered at the Katedral School), open to all students. ThIS believes that language learning in a multilingual environment promotes international mindedness, intercultural understanding and language proficiency for global citizenship. We believe that strong competence in one language (mother tongue) supports acquisition of additional languages. ThIS places in a great emphasis on home–school cooperation.
