It is with great regret that we have to inform you that the 2018/19 school year will be the last school year for ISSO.

There are not enough pupils for the coming school year. The Board and the shareholders are convinced that, even with the best of intentions, it would not be possible to keep the school running satisfactorily. 

Private. Bilingual. Individual.

The International School Solothurn (ISSO) is an open-minded, liberal, bilingual all-day school that allows children and young people to develop their individuality and full personality, thereby preparing them for the challenges of our global society.

Familial. Personal. Ambitious.

ISSO is open to local and international families. The school accompanies children from four years onwards in kindergarten, and leads them up to 6th class at the primary level.
Thanks to excellent specialist and interpersonal education and teaching, students can effortlessly transfer to public or private schools at any level.


Playing, learning, and learning to play: for 4- to 6-year-olds, learning is always playful and every playful activity is a natural learning process.

Primary School

We give every single student enough time and space to grow and individually develop his or her potential.

Day School

ISSO is a day school that takes its role in providing care and support even outside the classroom very seriously.
