About KIS International School Bangkok

KIS International School is an independent IB World school celebrating 25 years of academic excellence in central Bangkok. We are a diverse learning community of over 800 students from around 50 nationalities in Early Years to Grade 12. 

We will become One school, Two campuses with the addition of our new world class 60 acre second campus KIS Reignwood Park opening in August 2024 in Lam Luk Ka, Pathum Thani. 

KIS International School is the only school in Bangkok to offer all four International Baccalaureate programs: the Primary Years Programme (PYP), the Middle Years Programme (MYP), the Diploma Programme (DP), and the Career-related Programme (CP). 

Our graduates matriculate at top universities all over the world. Our reputation for academic excellence is supported by our consistently high IBDP scores which have seen us average 34.5 points over the last 5 years, well above the world average of 30 points. Success continues with students graduating KIS with a wide choice of offers stretching across 10+ countries and 120+ different universities and colleges each year.

KIS International School Bangkok is situated in a lush campus in a gated housing estate near the city center, providing a spacious learning environment that is away from noise and pollution while remaining easily accessible from both central Bangkok and the suburbs. 

KIS has a vibrant community atmosphere, and students and parents quickly feel at home and develop a sense of pride in the school. 

KIS International School Bangkok is a welcoming community, and learners benefit from a low student-to-teacher ratio of 1:8, ensuring that they are guided by dynamic, highly-qualified IB trained educators from around the world.

The campus boasts well-equipped science labs, state-of-the-art-design workshops, art and drama studios, libraries, an auditorium, real-grass sports fields, indoor air-conditioned courts, and three swimming pools.
