ITSW – the Place Where Linguistic Superpowers Are Born!
The International Trilingual School of Warsaw (ITSW) is a trilingual international school in Warsaw that has been educating children in the spirit of multilingualism and cultural openness since 2001. It was founded on a passion for education and the need to create a place where children can learn in three languages – from a very young age.
Starting with a small group of students, from the very beginning of ITSW, we have combined the highest educational standards with the idea of raising global citizens. In a world full of changes, speaking three languages and understanding different cultures gives children a real advantage – in their studies, personal lives, and future careers.

Trilingual Education From Nursery to Middle School
Today, ITSW is a dynamic and international educational community encompassing nurseries, preschools, primary and middle school. Hundreds of children learn three languages daily – English, Polish and one language of their choice: French, Spanish, Chinese, or Japanese. Languages are a natural tool for them to explore the world, not just a school subject.
Our educational programs are tailored to the child’s age and developmental stage, ensuring continuity of learning and smooth transitions between levels. Students develop not only linguistic skills but also social, emotional, and cognitive ones – in a warm, supportive environment.
ITSW Teachers – the Heart of Our Trilingual Education
It’s our teachers who make education at ITSW so exceptional. Their daily work involves not only teaching but also inspiring children to discover the world in three languages.
What sets our staff apart?
- International background – teachers from 5 continents and over 20 countries
