TSIS has been educating students since 1985. We have been managed by International Schools Services (ISS) since 2017. ISS is currently associated with over 400 schools around the world. 

The new TSIS is a thriving, family orientated school, with an incredibly strong and increasingly diverse community. Our students, staff and parents work together for the good of the learning process and the school as a whole. With high quality education and very reasonable fees, a new parent described TSIS as ‘Bangkok’s Hidden Gem’.

TSIS follows the British 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, our students have achieved some of Thailand’s top IGCSE results and received university offers from around the world.


During the past 35 years, the school has developed two exceptional campuses to educate students aged 2 to 18 years. Our Junior School is strategically located in Wongwianyai district of Bangkok and the Senior School is located on the south-eastern edges of the city, with a shuttle service for students from Bearing BTS Station. Both campuses have been developed to provide age appropriate learning environments for students. They are equipped with academic, sporting and other extracurricular facilities which outshine many other international schools.


For more information about TSIS please come arrange a time to visit us in person. We will be more than happy to show you around our school and answer any questions you have about the education we provide.
