SIS Swiss International School Basel

SIS Basel has operated since 1999 as a bilingual English-German day school serving ages 3 to 18. Students can pursue either Swiss Matura or the International Baccalaureate Diploma in their final years, giving families a choice between Swiss-recognized qualifications and the international pathway. The school follows a developmental approach that balances language learning with core academics across primary and secondary.

This school suits families staying in Basel longer term and wanting genuine bilingualism rather than English immersion alone. It's a good fit if you value the Swiss education system's rigor but need strong English alongside German, or if you're undecided between Swiss or international university options for your children.
