TSI International School

TSI International School (formerly TSIS / Thai Sikh) was established in 1985. Since changing management in 2017, the school continues through a significant period of growth and educates students from 35 countries.

TSI is a thriving, family orientated school, which educates students aged 2-18 years at two Bangkok campuses. It is a member of the Council of International Schools (CIS) and has excellent staff retention.

TSI delivers the English National Curriculum from Early Years Foundation Stage through to Key Stage 3, after which students are prepared for IGCSE and A Level examinations. In recent years, students’ results have been better than the UK national average and the average of British curriculum schools in South East Asia. Students receive university offers from around the world.

Both TSI campuses are equipped with academic, sporting and other extracurricular facilities which are envied by other international schools.

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.
