Key facts
| Address | 888/99 Lam Sai, Lam Luk Ka District, Pathum Thani 12150 -- as published in the school's own site footer. Note that our earlier postcode of 12130 was wrong, and that the school markets itself as a Bangkok school; the campus is in Pathum Thani province |
| Opened | August 2024, as KIS International School's second campus |
| Campus | Purpose-built 60-acre site with a 1,000-seat Performing Arts Center, an Aquatic Center and a Golf Development Academy |
| Grade range | Early Years (age 2) through Grade 12 (age 19) -- one of five schools in the province that takes a child all the way, and the one with the highest academic ceiling |
| Curriculum | Authorised IB World School offering the full continuum -- Early Years Prep (2-3), Primary Years Programme (3-11), Middle Years Programme (11-16), Diploma Programme (16-19) and the Career-related Programme (16-19). DP authorisation October 2025, first DP cohort August 2026 |
| Accreditation | Council of International Schools (CIS) accredited; ONESQA. Also publishes ISAT, ECIS, College Board, UCAS and Duke of Edinburgh's International Award affiliations. Note the distinction: CIS assesses the school, while IB and College Board authorise it to run their programmes |
| Boarding | Full and weekly boarding for ages 9-18 (from Grade 4), in a purpose-built boarding village with private bathrooms. The school describes itself as the only IB boarding school in Southeast Asia. This is the province's only boarding house of its kind and it makes KIS reachable from well outside Pathum Thani |
| Air quality | The only school in the province publishing an Air Quality and Heat Management Policy, with a public IQAir station for the campus linked from its own site. A public monitor reports outdoor air -- ask separately what filtration the classrooms actually have |
| Fees | BAANLYY publishes no per-school fee figures -- they change annually and a stale number is worse than none. See the school's own Fees and Scholarships page for the current schedule, including application, registration and boarding charges |

Overview
KIS International School Reignwood Park opened in August 2024 as KIS International School's second campus, at 888/99 Lam Sai in Lam Luk Ka District, on a purpose-built 60-acre site inside the Reignwood Park community. It is Pathum Thani's only full International Baccalaureate pathway and is now an authorised IB World School running the complete continuum — Early Years Prep from age two, the Primary Years Programme, the Middle Years Programme, and both the Diploma Programme and the Career-related Programme in the sixth form. Diploma Programme authorisation came in October 2025, with the first DP cohort starting August 2026. The school is accredited by the Council of International Schools.
Campus facilities include a 1,000-seat Performing Arts Center, an Aquatic Center and a golf academy, with full and weekly boarding for ages 9–18 in a purpose-built boarding village — the only provision of its kind in the province, and the reason KIS is a realistic option for families based well outside Pathum Thani. The IB Career-related Programme is worth singling out: it is the only vocationally-oriented sixth-form route in the province, and it pairs IB Diploma courses with a career-related study, which suits a student with a clear direction more than a broad Diploma would.
Two honest caveats. First, the campus is new and still filling: confirm that your child's specific year group is running and staffed this year rather than simply listed, and note that the first Diploma cohort has not yet sat an examination, so there are no results to judge. Second, KIS markets both its campuses as Bangkok schools — this one is in Pathum Thani province. BAANLYY is not affiliated with KIS, takes no paid placement, and publishes no per-school fee figures; confirm all current details directly with the school.
Who it's for
KIS Reignwood Park suits families who want a fully international, IB-track education with strong long-term university transferability, and who value a large, purpose-built campus with extensive arts, aquatics and sports facilities. The boarding option from Grade 4 also makes it workable for families who don't want to base themselves directly in Lam Luk Ka. Because the school is newer and actively growing into full IB authorisation, families should confirm current authorisation status and grade-level place availability directly, and apply well ahead of the August intake. Families wanting a longer-established, American-curriculum option should look at AIT International School (AITIS); families wanting a lower-cost bilingual route should look at SBS Rangsit or Sarasas Witaed Rangsit.
Location & getting there
KIS Reignwood Park is in the Reignwood Park development in Lam Luk Ka District, a newer, more spacious suburban area built around the school itself, with houses and villas rather than dense condo stock. Families based further away can lean on the school's boarding option, available from Grade 4, to reduce the daily commute. Confirm current transport and boarding arrangements directly with the school.
