Tsi International School

TSI International School is a thriving, family orientated school, which educates students aged 2-18 years at two Bangkok campuses. We follow 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, our students’ results have been better than the UK national average and the average of British curriculum schools in South East Asia. Our students receive university offers from around the world. TSI was established in 1985. Since the management team changed in 2017, the school has gone through a massive renewal process. There are now over 30 nationalities in our community. We are a CIS member school with excellent staff retention. Our Wongwianyai Campus is our first primary school for students aged 2-11 years. Our Bearing Campus was a secondary school only until August 2025 when we opened our second, state-of-the-art, primary school. Our Bearing Campus now offers parents a single-campus option for their child’s entire educational journey (Pre-Nursery – A levels). Both TSI campuses are very well equipped with academic, sporting and other extracurricular facilities which are envied by other international schools.
