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.
​
TSIS has two exceptional campuses to educate students aged 2 to 18 years. Our Wongwianyai Campus is for Early Years and Primary School students. Our Bearing Campus is our current Secondary School, with our second primary school to open in 2025. The Bearing Campus is on the south-eastern edges 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.

TSIS is a member of the Council of International Schools (CIS) and is accredited by the Western Association of Schools (WASC).
