With high quality education for reasonable fees, a new parent described TSI as ‘Bangkok’s Hidden Gem’.
Two Outstanding Campuses
TSI operates two campuses that together provide a complete 2–18 education:
- TSI Wongwianyai Campus is a nurturing setting for Early Years and Primary students with an ideal learning environment and impressive specialist facilities.
- TSI Bearing Campus offers a single-school option for families with classes from pre-nursery to sixth form. The enormous campus incorporates our new state-of-the-art primary school, secondary school and impressive sporting and extracurricular facilities.
Each campus is designed to support academic, creative and physical development while fostering a strong sense of belonging and community.
Our Identity and Purpose
Founded in 1985, TSI is one of Bangkok’s earliest established international schools with a long history of nurturing academic success and character development. Our mission is to empower students to be global citizens equipped with 21st-century skills, like communication, critical thinking, collaboration and creativity, that prepare them for lifelong achievement and leadership in an ever-changing world.
We are guided by a set of universal values, including integrity, compassion, diversity, self-discipline and service. These values shape our learning culture and support students in becoming resilient, respectful and responsible individuals.
Community, Growth and Accreditation
Since 2017, TSI has undergone a significant renewal and growth phase while remaining committed to retaining a friendly, respectful and globally-minded culture. In June 2026, our school was awarded accreditation with the Council of International Schools (CIS), a milestone that confirmed our commitment to international quality standards in education.
At TSI International School, we believe in challenging minds, embracing diversity and building character, preparing students not just for exams, but for meaningful and impactful lives.
