The schools relocating families actually choose in Pak Kret, Nichada Thani and around Mueang Nonthaburi, 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).
Nonthaburi punches well above its weight on schools for a province that's often mistaken for a Bangkok suburb rather than a destination in its own right. International School Bangkok (ISB) — Thailand's oldest international school — sits inside the Nichada Thani estate in Pak Kret, and Denla British School, a newer purpose-built campus a short drive away, gives families a full British pathway without crossing into central Bangkok. SISB's Nonthaburi campus and International Christian School Nonthaburi (ICSN) round out the options at a considerably lower price point. 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 Nonthaburi cost-of-living guide, and use the Nonthaburi hub to match a neighbourhood to your school.
A representative selection of the international and bilingual schools serving Nonthaburi. This is a starting point, not a ranking — the right fit depends on curriculum, budget and how far you're willing to commute.
| School | Area | Curriculum | Known for |
|---|---|---|---|
| International School Bangkok (ISB) | Nichada Thani, Pak Kret, Nonthaburi | American + IB Diploma | Thailand's oldest international school, tracing back to 1951 on the grounds of the US Embassy before relocating in 1992 to its purpose-built campus inside the Nichada Thani residential estate in Pak Kret. One of the most established and highly regarded American-curriculum schools in the country, PK–12, with an IB Diploma option in the senior years and a large, long-settled expat community built around the school itself. |
| Denla British School (DBS) | Om Kret, Pak Kret, Nonthaburi | British + IGCSE + A-Level | A newer (opened 2017) purpose-built 18-acre campus on Ratchapruek Road, about 30 minutes from central Bangkok via Chaeng Wattana and the expressway. Delivers an Enhanced British Curriculum in English through to IGCSE and A-Level, with Thai and Mandarin taught as subject languages, on facilities that include specialist science and tech labs, a 600-seat auditorium and an indoor pool. |
| SISB Nonthaburi Campus | Nonthaburi | Singapore + Cambridge (UK EYFS blend at nursery) | Part of the SET-listed SISB group, blending the Singapore curriculum's strength in maths and science through Primary with a hybrid Singapore–Cambridge Secondary programme, moving into Cambridge International AS and A-Level in the Sixth Form. Noticeably more affordable than ISB or Denla, and the practical choice for families who want a structured, exam-strong track without the top-tier price point. |
| International Christian School Nonthaburi (ICSN) | Pracharat Road, Mueang Nonthaburi | American (AERO / Common Core, AP-authorised) | Founded in 1997 on Pracharat Road on Bangkok's northern urban fringe, ICSN runs a Bible-based, American-standards curriculum (AERO and Common Core aligned) with Advanced Placement coursework available, small capped class sizes, and Chinese offered as an ECA. The most budget-friendly of Nonthaburi's four main options and popular with Christian and missionary families. |

Indicative annual fees for 2026. All four schools bill tuition separately from one-time application, assessment or registration fees (typically THB 150,000–260,000) and from uniforms, transport, meals and activities — budget for these on top of the headline tuition figure below.
| Stage | Annual fee (guide) |
|---|---|
| ISB — Pre-Kindergarten | THB ~640,000 / year |
| ISB — Elementary | THB ~985,000 / year |
| ISB — Middle School | THB ~1,104,000 / year |
| ISB — High School | THB ~1,162,000 / year |
| Denla — Nursery / Reception (EY1–EY2) | THB ~589,000–672,000 / year |
| Denla — Years 1–8 | THB ~800,000–880,000 / year |
| Denla — Years 9–13 (IGCSE / A-Level) | THB ~934,000–1,009,000 / year |
| SISB Nonthaburi — Nursery / Kindergarten | THB ~402,000–430,000 / year |
| SISB Nonthaburi — Primary (P1–P6) | THB ~471,000–567,000 / year |
| SISB Nonthaburi — Secondary / Sixth Form (G7–G12) | THB ~609,000–789,000 / year |
| ICSN — Kindergarten | THB ~394,000 / year |
| ICSN — Grades 10–12 | THB ~504,000 / year |
SISB and ICSN typically run 40–60% below ISB and Denla at comparable grade levels, making them the practical choice for families outside a corporate relocation package that covers full tuition. Always request the current fee schedule directly from the school before you commit.
Nonthaburi's school geography splits into two main clusters, with a value alternative for families willing to commute a little further:
| Area | Nearest schools | Why families live there |
|---|---|---|
| Nichada Thani & Pak Kret | International School Bangkok (ISB), Denla British School | Nonthaburi's established international-school corridor — Nichada Thani itself is a large gated estate built around ISB, with condos and houses in Pak Kret giving the shortest run to both ISB and Denla. The default choice for families who have already picked one of these two schools. |
| Mueang Nonthaburi (Pracharat Road area) | International Christian School Nonthaburi (ICSN) | Nonthaburi's older, riverside provincial centre, with ICSN on Pracharat Road; generally cheaper rent than Pak Kret, with the Purple Line and Chao Phraya boats for a commute into central Bangkok. |
| Bang Yai / Central Westgate | Commutable to all four schools; SISB Nonthaburi campus closest | Nonthaburi's newest condo supply, anchored by Central Westgate — good value for families prioritising modern housing over the very shortest school run, with the Purple Line for the daily commute. |
ISB runs an American framework PK–12 with an IB Diploma option in the senior years — a well-established path back to US, Commonwealth or IB-recognising universities, backed by Thailand's longest international-school track record. Denla teaches the Enhanced British Curriculum through to IGCSE and A-Level, with Thai and Mandarin as subject languages, on one of the newest campuses in the province. SISB Nonthaburi leans on the Singapore curriculum's strength in maths and science through Primary, moving into a Cambridge AS/A-Level track by Sixth Form — a structured, exam-focused option at a meaningfully lower price. ICSN delivers an American-standards curriculum in a Christian, Bible-based environment with AP coursework available, and is the most budget-friendly of the four. If you expect to relocate internationally again, ISB's IB Diploma or Denla's A-Levels travel especially well; if cost and a faith-based community matter more, SISB or ICSN are the practical choices.
ISB and Denla are the two most sought-after schools in the province, so start applications six to twelve months ahead of the August intake where possible — especially for the senior IB Diploma or A-Level years, where places can be limited. Expect an assessment or placement test, recent school reports and an interview at all four schools; SISB and ICSN are generally more flexible on entry timing outside the main intake. Gather transcripts, immunisation records and references before you leave your home country, confirm whether an employer relocation package covers tuition and the one-time registration fee (a significant cost at ISB and Denla), 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 — Pak Kret for ISB or Denla, Mueang Nonthaburi for ICSN, or Bang Yai/Westgate if you're prioritising newer housing over the shortest run.
International School Bangkok (ISB), inside the Nichada Thani estate in Pak Kret, is Thailand's oldest and one of its most established international schools, running an American curriculum through to an IB Diploma option. Denla British School, also in Pak Kret, is the newer British-curriculum alternative through IGCSE and A-Level. Which is "best" depends on the curriculum, budget and community fit your family wants — both are well-regarded, long-run options.
As a 2026 planning range: ISB runs from roughly THB 640,000 a year at Pre-Kindergarten up to about THB 1,162,000 in High School, plus a one-time THB 260,000 registration fee. Denla runs from about THB 589,000 at nursery to roughly THB 1,009,000 for A-Levels. SISB's Nonthaburi campus and International Christian School Nonthaburi (ICSN) are considerably more affordable, from around THB 400,000 up to THB 650,000–790,000 (SISB) or THB 394,000–504,000 (ICSN) a year. All figures exclude uniforms, transport, meals and one-time enrolment fees — confirm current fee schedules directly with each school.
Yes to both. ISB offers an American base through to the IB Diploma in its senior years, and Denla British School runs a fully British pathway to IGCSE and A-Level. SISB's Nonthaburi campus takes a different route — Singapore curriculum through Primary, moving into Cambridge International AS and A-Level by Sixth Form.
International Christian School Nonthaburi (ICSN), on Pracharat Road in Mueang Nonthaburi, is the main option — a Bible-based American curriculum (AERO/Common Core aligned) with Advanced Placement coursework, small class sizes and a lower price point than ISB or Denla.
Pak Kret — especially in or around the Nichada Thani estate — gives the shortest run to both ISB and Denla British School and is where most international-school families base themselves. Families choosing ICSN typically look toward Mueang Nonthaburi near Pracharat Road, while Bang Yai and the Central Westgate area offer newer, better-value housing that's still a commutable distance to any of the four. See our Nonthaburi hub for the full area breakdown.
