TSI is a thriving, family orientated British international school in Bangkok, Thailand, with a strong and increasingly diverse community (over 30 nationalities). Our well-qualified and highly-committed teachers use engaging inquiry-based teaching strategies to deliver the curriculum to students aged 2-18 years (Pre-Nursery to A-Levels). 

​

As a global international school in Bangkok, the students of TSI International School achieve excellent IGCSE and A-Level exams results and our graduates are offered places at universities all around the world.
​
Since 2017, TSI has gone through a massive renewal process and continues to experience considerable growth in student numbers. Despite our rapid growth, we are determined to remain a friendly, respectful, globally-minded school which develops critical and creative thinkers who drive their own learning.
​
TSI has two exceptional campuses to educate students aged 2 to 18 years. Our Wongwianyai Campus is for Early Years and Primary School students. Since the opening of our new state-of-the-art primary school at our Bearing Campus in 2025, we now offer a single-campus option for parents with children aged 2-18 years (pre-Nursery - A levels). The Bearing Campus is on the south-eastern edge of the city, with a shuttle service for students from Bearing BTS Station. Both campuses provide age-appropriate learning environments for students. They are equipped with academic, sporting and other extracurricular facilities which outshine many other international schools.

​

TSI is a member of the Council of International Schools (CIS) and will be fully accredited in the first quarter of 2026.
