ISB is authorised to be a PSAT and SAT testing centre and is also an examination centre for the Associated Board of the Royal School of Music (ABRSM).


History of ISB ISB was founded in1979 by Janet Galli, an American entrepreneur, as a response to a perceived need among expatriates for English-speaking schooling. The School began life with just 15 students and in a single schoolhouse. Student numbers grew rapidly, and at one point the School rented premises at 13 campuses in the Basel region. By 1995, ISB had become an IB World School, offering the Diploma Programme (DP) of the IB. By 1999, the School became a not-for-profit company, known as the International School of the Basel Region AG. That year it broadened its scope to include the IB Middle Years Programme (MYP). In 2002, Reinach - the first of ISB’s three current campuses – was opened. In the same year, ISB began to offer the IB Primary Years Programme (PYP). In 2007, the purpose-built campus at Aesch opened to accommodate the Junior School. Since 2012, students in the early years of the MYP have attended the campus at Fiechten. In the 35 years since its inception, ISB has grown exponentially and today educates over 1400 students representing approximately 60 nationalities.
