KIS International School Reignwood Park

KIS International School Reignwood Park. Think IB. Think KIS.

An IB education starts with a simple belief: students learn best when the learning is theirs. At KIS Reignwood Park, that belief shapes everything: How we teach, how students think, and how they meet a world that won't stop changing. We grow critical thinkers and confident problem-solvers, ready for what comes next.

Reignwood Park is our second campus, building on nearly 30 years of IB excellence at our sister school, KIS Bangkok. We welcome students from Early Years (age 2) upward as day students, and from Grade 4, as weekly or full boarders at Bangkok's only full IB boarding school.

The IB Experts

We are Bangkok's IB experts. The proof is in the numbers: an IBDP average of 34.5 over the past five years at KIS Bangkok, comfortably above the world average of 30. And every year, our graduates receive offers from the most prestigious universities. Imperial College London, University of Melbourne, UCL, and more.

A World-Class 60-Acre Campus

Space to grow, and room for every passion. Early Years, Primary, and Secondary each have their own self-contained environment — a campus that meets students where they are. Around them: a 1,000-seat Auditorium Centre and the indoor Wolves Sports Complex, home to a 1,000-seat Sports Arena, an Aquatic Arena, a Golf Development Academy, a fully equipped Gymnastics Hall and a Fitness Centre. All set within the Reignwood Park community — a rare combination of beautiful landscapes, calm, and modern living.

Bangkok's Only Full IB Boarding School

From Grade 4 (age 9), students can board — weekly or full — at Bangkok's only full IB boarding school. Pair the IB curriculum with a vibrant on-campus boarding village, and the day opens up: more time to develop talents, build study habits, and grow into independence. Bedrooms are stylish and comfortable, each with a private bathroom and generous storage — four or two students per room, and single rooms for our Seniors. Boarders have direct access to the full 60-acre campus, plus their own dining hall, study spaces, and places to relax. More hours in the day. More room to grow. And friendships that last well beyond graduation.
