Welcome to TSI International School.
It is a privilege to serve as Head of School and to welcome you to a community that has grown remarkably while remaining true to its founding values. Today, TSI educates more than 750 students across our Wongwianyai and Bearing campuses, yet we continue to pride ourselves on being a school where every child is known, valued and supported as an individual.
In 2026, TSI was awarded full accreditation by the Council of International Schools (CIS). This internationally recognised achievement reflects years of hard work by our staff, students, parents, Board members and alumni. During the accreditation process, the CIS evaluation team described TSI as having an “unconscious commitment to the care and well-being of all its members” and “a warm and mutually supportive environment where all feel challenged, included and respected.” I believe these comments capture the essence of our school and the culture that we have built together over many years.
Recent years have been an exciting period in TSI’s history. The opening of our Bearing Primary Campus, the renewal of facilities across both campuses and plans for further development all reflect our commitment to continual improvement. At the same time, we remain committed to providing a high-quality international education at fees that remain accessible to a wider range of families.
Our younger learners benefit from an engaging programme based on the National Curriculum of England, while our secondary students achieve strong outcomes through Cambridge International programmes and a range of pathways designed to support their individual aspirations. However, success at TSI is measured by more than examination results. We are equally proud of the confidence, resilience, compassion and character that our students develop during their time with us.
What truly makes TSI special, however, is its people. We are a diverse and welcoming community where relationships matter, differences are embraced and ambition is balanced with genuine care for others. It is a place where students are encouraged to challenge themselves, support one another and contribute positively to the world around them.
