At SIS we believe in an holistic educational and social experience that will bring out the best in every learner.  Whether it be Forest school or IGCSE your child will receive quality time and educational experiences in our small class environments.

Sønderborg International School offers education at three levels with a high degree of learner support integrated at all levels:

1. Primary (Year 1-4) – Core subjects are connected across the curriculum enabling students to gain a broader understanding of how, and why, their learning is relevant.

2. Lower Secondary (Year 5-7) – Our balanced and broad curriculum provides students opportunities to engage in Arts, Languages, STEM subjects, the Humanities and Sports. This balance is reflected in our strong academic results across all academic and creative subjects.

3. Upper Secondary (Year 8-10) – In the upper Secondary students work towards CIE IGCSE qualifications. Our students have the opportunity to study English, Maths, Science, Global Perspectives, Danish, German, History and Business Studies.

We also offer Danish Mother Tongue to students who speak Danish at mother tongue level. We follow the guidelines set out in the Ministry of Educations “Fælles Mål” for Danish. All Danish mother tongue lessons, in both Primary and Secondary, have this common goal and the final exam at the end of Upper Secondary is “Folkeskolens Afgangsprøve for 9. klasse”.
