70th anniversary

Celebrating our impact | 1951-2021

In the 2021–2022 academic year, Stockholm International School marks its platinum jubilee.

For seven decades, we have made a huge contribution our students, our families and to the city of Stockholm. In 1951, our founding year, the SIS student body boasted 15 different nationalities. Today, we challenge and inspire almost 700 students from nearly 60 countries with our globally recognised academic programme.
