The schools relocating families actually choose around AIT, Thammasat and Rangsit, what tuition really costs, how the curricula differ, and where to live for the shortest school run. Fees are 2026 guide ranges in Thai baht (≈ THB 35–36 = USD 1).
Pathum Thani's school scene is shaped by the institutions that put the province on the map — Thammasat University's Rangsit campus and the postgraduate Asian Institute of Technology (AIT). AIT International School (AITIS), founded in 1974 inside the AIT campus itself, is Pathum Thani's longest-running international school and remains the natural choice for academic and research families. KIS International School Reignwood Park, which opened in August 2024 on a purpose-built 60-acre campus in Lam Luk Ka, brought a full IB pathway to the province for the first time. Satit Bilingual School of Rangsit University (SBS Rangsit) and Sarasas Witaed Rangsit School round out the options at considerably lower price points for families who want a bilingual track without full international-school fees. Below: the schools families choose, typical tuition, where to base yourself, the curricula explained, and how to plan your move around a school choice. For day-to-day budgeting pair this with the Pathum Thani cost-of-living guide, and use the Pathum Thani hub to match a neighbourhood to your school.
A representative selection of the international and bilingual schools serving Pathum Thani. This is a starting point, not a ranking — the right fit depends on curriculum, budget and how far you're willing to commute from AIT, Thammasat or Rangsit.
| School | Area | Curriculum | Known for |
|---|---|---|---|
| AIT International School (AITIS) | Inside the AIT campus, Khlong Nueng, Khlong Luang | American-based, modified to international standards | Founded in 1974 within the Asian Institute of Technology to serve AIT staff and postgraduate-student families, AITIS has been open to the wider public since 2007. All instruction is in English, with Thai language classes offered for both native speakers and newcomers. Small, close-knit and deeply tied to Pathum Thani's international academic and research community — the natural first call for anyone relocating for AIT or Thammasat. |
| KIS International School Reignwood Park | Reignwood Park, Lam Luk Ka | International Baccalaureate (IB candidate — PYP, MYP, DP) | Opened in August 2024 as KIS International School's second campus, this purpose-built 60-acre site brings a full IB pathway to Pathum Thani for the first time, from Early Years to Grade 12. Facilities include a 1,000-seat Performing Arts Center, an Aquatic Center and a Golf Development Academy, with both day places and boarding available from Grade 4 — a practical option for families based further out or wanting to reduce a long daily commute. |
| Satit Bilingual School of Rangsit University (SBS Rangsit) | On the Rangsit University campus, Lak Hok, Mueang Pathum Thani / Thanyaburi border | Bilingual — IB Primary Years Programme + Cambridge IGCSE / A-Level | Runs the IB Primary Years Programme through elementary grades before moving into a Cambridge International pathway to IGCSE and A-Level, taught bilingually in English and Thai with Chinese offered as an additional language. Takes students from age two through eighteen, with a boarding option, on the campus of Rangsit University near Future Park — one of the more structured, exam-strong bilingual choices in the province. |
| Sarasas Witaed Rangsit School | Thanyaburi, off Rangsit–Nakhon Nayok Road | Thai Ministry of Education curriculum + English Program (bilingual) | Part of the Sarasas Witaed network, Thailand's largest bilingual school group with more than 20 campuses and over 30,000 students nationwide. The Rangsit campus follows the group's English Program model — Thai national curriculum content delivered bilingually — and is consistently the most budget-friendly option covered here, popular with Thai-foreign families who want an English-medium track without full international-school fees. |

Indicative annual fees for 2026. Schools bill tuition separately from one-time application, assessment or registration fees and from uniforms, transport, meals and activities — budget for these on top of the headline tuition figure below.
| Stage | Annual fee (guide) |
|---|---|
| AITIS — whole school (varies by grade) | THB ~400,700–873,800 / year |
| KIS Reignwood Park — Early Years to Grade 12 | THB ~560,000–997,600 / year |
| KIS Reignwood Park — one-time Registration Fee | THB 260,000 (plus THB 6,000 application fee) |
| SBS Rangsit — Toddler–Year 1 | THB ~254,700 / year |
| SBS Rangsit — Year 5–6 | THB ~339,400 / year |
| SBS Rangsit — Year 11–13 | THB ~388,500 / year |
| SBS Rangsit — full boarding (7 nights/week) | THB ~204,000 / year |
| Sarasas Witaed English Program (network range) | THB ~280,000–450,000 / year |
SBS Rangsit and Sarasas Witaed Rangsit typically run 40–70% below AITIS and KIS Reignwood Park at comparable grade levels, making them the practical choice for families outside a corporate relocation package that covers full tuition. Younger families based near Mueang Pathum Thani's riverside area may also want to look at Thai International School, a WASC-accredited American-curriculum option for Nursery–Grade 6 — contact the school directly for current fees. Always request the current fee schedule directly from any school before you commit.
Pathum Thani's school geography splits into three main clusters, each tied to a different institution:
| Area | Nearest schools | Why families live there |
|---|---|---|
| AIT & Thammasat Rangsit corridor (Khlong Luang) | AIT International School (on campus) | Pathum Thani's academic core — low-rise apartments and staff/student housing within walking or short motorbike distance of AIT and Thammasat University's Rangsit campus, plus easy access to Thammasat University Hospital. The default base for anyone relocating specifically for AIT or Thammasat. |
| Rangsit University / Future Park (Thanyaburi–Lak Hok border) | SBS Rangsit, Sarasas Witaed Rangsit | Pathum Thani's commercial and condo hub, anchored by Future Park and Zpell malls, with the widest choice of rental agents and everyday amenities plus the SRT Red Line terminus for the run into Bangkok. |
| Reignwood Park & Lam Luk Ka | KIS International School Reignwood Park | A newer, more spacious suburban development built around the school itself, with houses and villas rather than dense condo stock — the boarding option at KIS also takes the pressure off families based further away. |
AITIS runs an American-based curriculum modified to international standards, taught entirely in English with Thai language support — a familiar, straightforward path for families used to a US-style school system, backed by half a century of history inside the AIT community. KIS Reignwood Park is Pathum Thani's only full IB pathway (PYP, MYP and DP candidacy), a well-recognised route into universities worldwide and the strongest choice for families who expect to relocate internationally again. SBS Rangsit blends the IB Primary Years Programme with a Cambridge IGCSE/A-Level track at secondary level, taught bilingually in English and Thai with Chinese as an additional subject — a structured, exam-focused option at a meaningfully lower price. Sarasas Witaed Rangsit delivers the Thai national curriculum bilingually through its English Program, the most affordable route to English-medium instruction covered here and a strong fit for Thai-foreign families who don't need a fully international track. If cost and flexibility matter most, Sarasas Witaed or SBS Rangsit are the practical choices; if a fully international curriculum and long-term transferability matter more, AITIS or KIS Reignwood Park are the stronger fits.
KIS International School Reignwood Park is new and actively growing into its IB candidacy, so places and grade-level availability can shift year to year — confirm current IB authorisation status and start applications well ahead of the August intake. AITIS, tied closely to the AIT community, has historically prioritised places for AIT staff and student families, so apply early if you're joining the university or institute directly. SBS Rangsit and Sarasas Witaed Rangsit are generally more flexible on entry timing and offer rolling admissions outside the main intake. Expect an assessment or placement test, recent school reports and an interview at most schools. Gather transcripts, immunisation records and references before you leave your home country, confirm whether an employer or university relocation package covers tuition, and shortlist a backup school in case your first choice doesn't have a place for your child's year group. Once a school is confirmed, choose your home around its location and your daily commute — Khlong Luang for AITIS, Rangsit University/Future Park for SBS Rangsit or Sarasas Witaed, or Lam Luk Ka for KIS Reignwood Park (or lean on its boarding option if you're based further out).
It depends on what you're optimising for. KIS International School Reignwood Park, which opened in August 2024 on a 60-acre campus in Lam Luk Ka, is the province's only full IB-track option (PYP, MYP and DP candidacy). AIT International School (AITIS), founded in 1974 inside the Asian Institute of Technology, is the longest-established and most deeply embedded in Pathum Thani's academic community. Both are strong, well-regarded choices — the right fit depends on curriculum preference, budget and which institution brought you to the province.
As a 2026 planning range: AIT International School runs roughly THB 400,700–873,800 a year depending on grade. KIS International School Reignwood Park runs from about THB 560,000 in Early Years up to roughly THB 997,600 in the senior grades, plus a one-time THB 260,000 registration fee. Satit Bilingual School of Rangsit University (SBS Rangsit) is considerably more affordable, from about THB 254,700 up to THB 388,500 a year. Sarasas Witaed Rangsit's English Program, part of Thailand's largest bilingual network, runs roughly THB 280,000–450,000 a year network-wide. All figures exclude uniforms, transport, meals and one-time enrolment fees — confirm current fee schedules directly with each school.
Yes. KIS International School Reignwood Park in Lam Luk Ka is a Candidate School for the IB Primary Years, Middle Years and Diploma Programmes, offering a full IB pathway from Early Years to Grade 12. Satit Bilingual School of Rangsit University also runs the IB Primary Years Programme at elementary level before moving into a Cambridge IGCSE/A-Level pathway for secondary.
Sarasas Witaed Rangsit School, part of the Sarasas Witaed network — Thailand's largest bilingual school group, with more than 20 campuses and over 30,000 students — is the most budget-friendly option covered here, teaching Thai national curriculum content bilingually in English and Thai. Satit Bilingual School of Rangsit University is a step up in price but still considerably cheaper than the province's international schools, blending IB and Cambridge pathways bilingually.
Base yourself near the institution that decides your school. Families at AIT International School typically live on or near the AIT campus in Khlong Luang. Families choosing SBS Rangsit or Sarasas Witaed Rangsit generally settle around Rangsit University and Future Park, Pathum Thani's main commercial and condo hub. KIS International School Reignwood Park families cluster in the newer Reignwood Park development in Lam Luk Ka, though the school's boarding option also suits families based further away. See our Pathum Thani hub for the full area breakdown.
