IST at a Glance

International School of Tallinn was established in 2017 as a part of the Mainor, an Estonian capital based development company founded in 1971. Today the Mainor Group as  a corporation includes 15 subsidiaries and affiliated companies (e.g. real estate and city development, education, woodworking, metal working, energetics). Mainor Group has provided high-level education since 1992, when today’s Estonian Entrepreneurship University of Applied Sciences started as Mainor Business School.

IST is conveniently located at Keevise 2, a two-minute walk from the tram stop and close to bus stops.

We had grades 1-8 for the school year 2018-2019, and grades 9-10 are now open. Grades 11-12 will open in 2020. Preschool starts from age 3 to age 6.

We follow the Estonian national curriculum within the framework of the International Baccalaureate (IB) Programme.

Digital options are promoted throughout our education services. This enables us to increase student motivation, use interactive programmes and tests, apply a personalised approach, and take into account the results of learning analytics.

We hope and trust that we will earn a reputation for excellence in the provision of international education services.

The school’s language of instruction is English. The students may choose French, German, or Russian as their primary world  language of study.

At IST, our aim is to implement cutting-edge learning concepts that cultivate fundamental and problem-solving skills as well as research-based learning, interdisciplinary integration, teamwork, and creativity.
