It is the international aspect of the school that we particularly value ...... the experiences and friendships which they gain in their multi-national and multi-cultural classrooms are priceless.
Over the next twenty years the school began to welcome students from ever more diverse countries and in 2004 became the British International School of Stavanger. The International Pre-School was incorporated in 2008.
In 2007, the school made the decision to extend provision to include a secondary school. As part of that development, the school began incorporating the International Baccalaureate Programmes (IB) into their curriculum.
In 2019, the British International School of Stavanger made the transition from private school towards a more inclusive independent school model, BISS Gausel 'friskole'. As a result of this process BISS Sentrum was founded as a sister school to BISS Gausel. Currently BISS Sentrum is a candidate school for the International Baccalaureate (IB) Primary Years Programme and Middle Years Programme and is pursuing authorisation as an IB World School.
