International Schools in Thailand: 2026/27 Fees From Five Schools Compared

Tuition at five Thai international schools runs from THB 413,400 a year in Lanna's Early Years to THB 1,256,700 in Shrewsbury's Year 12. Before the first day each school also charges non-refundable one-off fees, from THB 96,000 at Lanna to THB 255,500 at Bangkok Patana.

By Vincent Nguyen and team

The one-off fees before day one shape the first-year budget as much as tuition does. Lanna in Chiang Mai asks THB 96,000 in non-refundable one-off fees, and Bangkok Patana asks THB 255,500 for a first child. Tuition then ranges from THB 413,400 a year in Lanna’s Early Years to THB 1,256,700 in Shrewsbury’s Year 12.

Fees side by side

Fees are in Thai baht for the 2026/27 school year. Each cell is the youngest or oldest stage the school prices, so compare stages, not school names.

The one-off total adds the application fee to the entrance, admission, registration, foundation or guaranteed-place fee. Patana’s total is THB 255,500, Shrewsbury’s THB 230,000, Harrow’s THB 230,000, Prem’s THB 136,000 and Lanna’s THB 96,000. With the refundable deposit added, the cash due before the first day is:

• Patana: THB 305,500.
• Shrewsbury: THB 455,000.
• Harrow, day student: THB 430,000.
• Prem: THB 186,000.
• Lanna: THB 109,000.

Youngest stages differ by school: Nursery at Patana, Shrewsbury and Harrow (full day), Early Years 1 to 3 at Prem and Early Years at Lanna. Final years are Year 12 at Patana and Shrewsbury, Year 12 to 13 at Harrow and Lanna, and Grade 9 to 12 at Prem. Tuition is the largest line, and the sections below show what else each school bills.

Visas for a child

A child studying at a Thai private school can hold a Non-Immigrant ED visa, and the school writes a letter confirming enrolment, signed by an authorised person. A private school must hold a licence to operate before the Immigration Bureau grants a student extension. Ask the school for its licence before you pay the entrance fee.

For a formal private school the Bureau grants the period the school certifies, up to 1 year at a time. A non-formal private school gets up to 90 days at a time and 1 year in total. The ED visa guide covers the extension step by step.

If a parent holds another visa, a child can often join it:

• A Non-Immigrant O dependant visa covers the spouse and children of a Non-Immigrant B, ED or O-A holder.
• For an ED applicant’s dependants, the embassy checklist asks for a cover letter from the school or university.
• Children under 20 of a DTV holder can apply under the family purpose. See the DTV visa guide.

The LTR visa guide explains who counts as a dependant under that programme.

Notice, refunds and returning

• Shrewsbury refunds the deposit on graduation, or on written notice at least 60 school days before the child leaves.
• Harrow needs one full term of written notice on its withdrawal form.
• Prem needs one term of written notice for the deposit.
• Lanna charges the enrolment fees again if a student returns after more than 12 months.
