KIS International School (Reignwood Park Campus)

KIS Reignwood Park is the second campus of KIS International School, which has run its original IB school in Huai Khwang since 1998. The new campus opened in August 2024 on a 60-acre (150-rai) site in Lam Luk Ka, Pathum Thani, north of Bangkok beyond Rangsit. Its teaching blocks are arranged around a landscaped lake, and the site was planned for well over 1,000 students as it fills up. It has its own admissions team and fee schedule, separate from the Bangkok campus.

Like the Huai Khwang campus, Reignwood Park teaches only International Baccalaureate programmes. Early Years Prep (ages 2–3) leads into the Primary Years Programme (ages 3–11) and the Middle Years Programme (ages 11–16). In the final two years, students take the IB Diploma or the IB Career-related Programme. Boarding is the main difference from the Bangkok campus: students from Grade 4 (about age 9) can board full-time or weekly in a boarding village with en-suite rooms and a 24-hour health centre. Students come from around 50 nationalities, and the campus also runs a golf academy.

Facilities include a performing arts centre, sports halls with seating for about 1,480 spectators, gymnasiums, a swimming pool, tennis courts, dance studios and science laboratories. Day tuition for 2025–2026 was about THB 877,000 a year for Grades 1–5, THB 945,000 for Grades 6–10 and THB 998,000 for Grades 11–12, with lower rates for kindergarten. New families also pay a registration fee of about THB 269,000 and a development fund contribution. Boarding fees are charged on top and are available from the admissions office.
