What is the best international school in Bangkok?

It depends on your preferences. International School Bangkok (ISB) is consistently top-ranked with an American curriculum. Shrewsbury International School offers a prestigious British education. NIST and Bangkok Patana are excellent IB options. Visit schools in person, as the 'best' school is the one that fits your child's needs and your family's values.

Can my child attend a Thai public school instead?

Yes, foreign children can attend Thai public schools, and tuition is essentially free. However, all instruction is in Thai, and the teaching style is quite different from Western education systems. Some public schools in Bangkok and Chiang Mai have English programs (EP) where core subjects are taught in English for an additional fee of 30,000-80,000 THB per year. This can be a good option for families on a budget who want their children to integrate into Thai culture and learn the language.

When should I apply for international school admission?

Apply as early as possible, ideally 6-12 months before the intended start date. The main admission season runs from January to March for August enrollment. Top schools like ISB, Bangkok Patana, and Shrewsbury have waiting lists, particularly for popular year groups. Most schools require entrance assessments (age-appropriate evaluations for younger children, academic testing for older students), previous school records, and a family interview. Mid-year transfers are sometimes possible if spots are available.

Do international schools follow the Thai school calendar?

Most international schools in Thailand follow either a August-to-June or September-to-June academic year similar to Western schools, with a long break in June-July. Some schools following the British system may use a September-to-July calendar. The Thai public school year runs from May to March, so international school calendars differ significantly. Key holiday periods include October half-term break (1-2 weeks), December-January Christmas break (2-3 weeks), and the long summer break (June-August). Schools also observe Thai public holidays such as Songkran in April.

International school fees in Thailand are structured with several components that families should budget for carefully. Application fee: 2,000-5,000 THB per child, non-refundable, paid when submitting the application. Registration or enrollment fee: 50,000-200,000 THB as a one-time payment upon acceptance, which secures the student’s place. Tuition fees: the largest component, ranging from 150,000-350,000 THB annually at mid-range schools to 500,000-900,000+ THB at premium institutions. Fees increase as students move to higher year groups, with secondary school typically costing 30-50% more than primary. Additional costs include uniforms (5,000-10,000 THB per year for full sets), school meals (15,000-30,000 THB per year), door-to-door school bus service (30,000-60,000 THB per year), and extracurricular activities, which may be included or cost an additional 5,000-20,000 THB per term. Some schools also charge a refundable deposit of 50,000-100,000 THB, returned when the student leaves. Budget approximately 200,000-500,000 THB per child per year for a mid-range international school, or 600,000-1,000,000+ THB for premium schools like ISB, Shrewsbury, or Bangkok Patana.
