Our Team, Our Opening Hours and How to Reach Us

Greeting from the Principal

Welcome, dear parents and students,

SIS is state-recognised and offers a comprehensive bilingual education concept from kindergarten to the Abitur, realised in an innovative all-day format. Our curriculum is based on the requirements of the Baden-Württemberg education plan, supplemented by specific curricula for language teaching, writing skills and science.

As an IB World School, we pursue an international orientation and enable our students to obtain the International Baccalaureate (IB) Diploma parallel to the Abitur. Our international faculty is specially trained for this purpose.

We are aware that growing up in a constantly changing world can be fascinating but also challenging. Therefore, our aim is to develop responsible and open-minded young people who have the skills, competences and holistic thinking to make a positive impact on our society. We foster an open-minded environment in which students from over 40 nations treat each other with integrity and respect and share their enthusiasm for learning. 

In the spirit of a practical and lively educational partnership, we seek to work closely with parents to support the development of our students in the best possible way.

We warmly welcome you to the lively school community of SIS Swiss International School Stuttgart-Fellbach.
