Thai Curriculum International Schools in Thailand

About international schools in Thailand

Thai-curriculum international schools in Thailand are typically private or bilingual schools that deliver the country’s Basic Education Core Curriculum (often cited as B.E. 2551 and its revisions) while adding increased English instruction and international-style subjects. Many operate as bilingual Thai - English programmes or as private schools that blend Thai national standards with elements of Western curricula, so families should expect a mix of Thai-language classes (Thai language, social studies, civics) and English-medium lessons in maths, science or other subjects. Fees and extra costs vary widely by city and type of school, but families commonly see annual charges in a broad band from more economical private/bilingual options up to much higher international-style tuitions in major urban areas. Admissions and term calendars differ - some schools follow the Thai Ministry calendar (mid-May start) while others align to Western/three-term calendars (August/September start), so check the individual school’s calendar and application deadlines before relocating.

FAQs for Thailand

What exactly does “Thai-curriculum” mean in an international or bilingual school context?
A Thai-curriculum school teaches the Thai Basic Education Core Curriculum (national standards set by the Ministry of Education) as its primary framework, often required for Thai nationals, while some schools add English-medium lessons or foreign assessment elements. This means students cover the Thai syllabus and cultural content but may also study additional international subjects or follow parallel programmes to support English proficiency.
How is a Thai-curriculum bilingual school different from an international school that uses IB or Cambridge?
Bilingual Thai-curriculum schools use the national Thai curriculum as the core programme and prioritise Thai language and civic content, whereas international schools follow external curricula such as the International Baccalaureate or Cambridge/UK or US standards and usually deliver most lessons in English. Families choosing between them should consider whether they want formal recognition of Thai national learning outcomes (useful for local progression) or an externally-validated international qualification for overseas university entry.
What languages are used for teaching and how much Thai will my child learn?
Most Thai-curriculum international and bilingual schools teach a mix of Thai and English: Thai is taught as a subject and used for parts of the national curriculum, while English is commonly used for maths, science or additional international courses to build bilingual fluency. Schools vary in how much time they allocate to each language, so request a sample timetable and language policy to see the balance for your child.
How much should we budget for tuition and extra costs?
Costs vary by city and by whether the school is a low-fee private bilingual school or an international-style campus in Bangkok or a tourist region; published guides and cost-of-living summaries put typical annual ranges across the sector from relatively modest private/bilingual fees at the lower end to substantially higher international-style tuitions in major cities. Parents should allow extra for registration/development fees, transport, uniforms, meals and examination charges and ask schools for a full fee schedule before committing.
When should we apply and what should we check during admissions?
Application timing depends on the school calendar: many Thai-system schools follow the Ministry calendar with a mid-May start, while others run a Western three-term year beginning in August or September, so apply well ahead of the intake you want and confirm testing or interview dates directly with the school. During visits, check the language policy, sample timetables, how Thai curriculum requirements are assessed, extracurricular provision, pastoral support and the school’s approach to supporting students new to Thai or English.
