If termination is not notified at least ten calendar weeks prior to the end of the week in which the student leaves, a compensation charge of 25% of the School Fees for the corresponding semester may apply.

Curriculum details
BKA International School is a bilingual private school offering English and German instruction from early years, with French introduced from Grade 3. The early years use Curriculum 21 together with the IB Primary Years Programme (PYP), with a play-based approach and emphasis on language development. Primary builds on that foundation with a developmentally appropriate curriculum that fosters knowledge, skills, and curiosity year by year. In Secondary, the program uses IGCSEs and A-Levels to prepare for Swiss and international universities. BKA holds Basel-Stadt Alignment and Transition Agreement ensuring the IB curriculum aligns with Lehrplan 21 and is an IB World School. The school operates across Wettstein, Spalentor, Gellért, and Rittergasse campuses serving ages 3 months through 18 years.
Curriculum details
SIS Basel offers an English/German bilingual kindergarten with continuity from Kindergarten to College. The curriculum combines the Swiss curriculum (Lehrplan 21) with the British curriculum and SIS-developed content to promote bilingualism.

The six curriculum areas are Personal and Social Development; Language Development; Mathematics; Knowledge and Understanding of the World; Physical Development; and Creative Development.

The day runs from 7:30 a.m. to 6 p.m., with after-school care and a range of clubs, and regular trips and events form part of the program.
