Boarding in Thailand

Boarding schools in Thailand — true total cost

Tuition is only half the boarding bill. This page puts day tuition and published boarding charges side by side for the 18 schools whose boarding rates we captured from their own schedules (October 2026), then explains how to judge boarding well.

Totals

Tuition + boarding: the total year cost

Total = the school's published day-tuition range plus its published boarding charge (the lowest boarding band against the lowest tuition band). Boarding figures are school-supplied, quoted with their basis; where a school publishes per-term or per-semester prices, the annualised figure and its arithmetic are stated. Full methodology: how we verify.

Judgement

The boarding decision guide

Who boarding suits

Boarding works best for children who are ready for structured independence — usually from around age 10–13, though schools here take boarders from Year 3 — and for families whose alternative is a very long daily commute, frequent relocation, or parents based outside Thailand. It suits children who thrive on routine, team sport and a full activity programme. It is a harder fit for children who are still settling after a big move, or who need intensive daily parental support for learning or health needs — ask honestly how the school handles both before deciding.

What to inspect on a visit

  • The boarding house at night, not just on open day: visit at prep time or bedtime if the school allows it — staffing ratios and atmosphere differ from the tour version.
  • Who is actually on duty: house parents' experience, overnight cover, and what happens when a child is ill at 2 a.m. (infirmary, hospital transfer, who calls you).
  • Rooms and privacy: dorm size by age, study space, secure storage, phone/device policy by year group.
  • Food: eat the boarder's dinner if you can; check weekend catering specifically — it is where standards slip.
  • Weekends: how many boarders stay in on a normal weekend, what is organised, and how exeats (weekends away) work.

Pastoral-care questions to ask any boarding school

  • Who is my child's named house parent / tutor, and how often will we hear from them?
  • How are homesickness and bullying handled in the first term — what is the actual protocol?
  • What safeguarding training do boarding staff hold, and who is the designated safeguarding lead?
  • How do boarders contact home, and what is the school's device policy at night?
  • What medical cover is included in the boarding fee, and what is charged extra?
  • For weekly boarders: what are the exact arrival/departure windows, and what happens on public-holiday weekends?

Boarding types, plainly

Full boarding — seven nights a week in term; the standard for students whose families live abroad. Weekly boarding — school nights only, home at weekends; common in Bangkok, where many families live in the city but face long commutes. Flexi / temporary boarding — individual nights as needed, charged per night (published examples here run ฿2,250–2,400/night); useful for exam periods, late fixtures and parents' travel.

Questions

Boarding FAQ

How much does boarding add to tuition in Thailand?

At the schools that publish boarding rates, roughly ฿120,000–653,000 a year on top of day tuition (official schedules captured in our October 2026 pass). Full boarding at the large British-style boarding schools clusters around ฿425,000–570,000 a year.

What is the difference between full, weekly and flexi boarding?

Full boarding is seven nights a week through term. Weekly boarding is school nights only (typically five nights), with weekends at home. Flexi boarding is ad-hoc nights — for late activities, exams or family travel — usually charged per night.

From what age do Thai international schools take boarders?

It varies: Regents Pattaya and Bloomsbury Hatyai publish boarding from Year 3 (around age 7–8), Regent's Bangkok from age 8 / Year 5, Rugby from age 10. Most schools publish their minimum age and boarding grades on their boarding pages; our table shows what each school states.

Are boarding fees on CredRadar verified?

The boarding figures in the table above are school-supplied: captured from each school's own published schedule in October 2026 and quoted with their basis (per year, per term or per semester). Where a figure is annualised from a per-term price, the table says so and shows the arithmetic.
