Thailand – Education and Schools

How good is the education system in Thailand?

Over recent decades, Thailand’s education system has expanded considerably in both reach and ambition, with access to schooling improving steadily across the country. The government has treated education as a key driver of social and economic advancement, resulting in a broad and wide-ranging state system. That said, objective international evaluations suggest that academic outcomes leave considerable room for improvement.

According to the OECD’s Programme for International Student Assessment (PISA) 2022 — which covered 81 countries and economies — Thai students placed 58th for both mathematics and science, and 64th for reading. These results position Thailand well below the OECD averages and behind regional counterparts such as Singapore and Vietnam. It is worth noting, however, that PISA measures the performance of 15-year-olds in state-type institutions and does not capture students attending international schools.

Thailand’s average scores in mathematics, science, and reading were 394, 409, and 379 respectively, compared to OECD averages of 472, 485, and 476. Performance across all three subjects declined relative to 2018 results, and in each case, 2022 scores were the lowest recorded in any assessment to date — continuing and deepening a downward trend that first became apparent between 2012 and 2015.

Thailand’s Deputy Minister of Education pointed to the lingering effects of the COVID-19 pandemic as a contributing factor, while also acknowledging entrenched issues of inequality and uneven access to technology. In October 2023, a National PISA Committee was established with the aim of improving outcomes in the 2025 assessment cycle. For the most current data, readers can consult the Thailand Ministry of Education and the OECD PISA database.

Despite these weaknesses in the state sector, it is essential to distinguish between national schooling and the international school landscape. Bangkok alone has 175 international schools, among them 38 following the British curriculum, 21 following the American curriculum, and 23 IB schools. The majority deliver education to a very high standard, and for expatriate families, this sector represents a compelling and well-established alternative to local government schools.

At what age is education compulsory in Thailand, and how is schooling structured by age?

The Thai government, through the Ministry of Education, is the primary provider of education from pre-school through to senior secondary level. A free basic education up to age 15 is enshrined in the Thai constitution. Compulsory schooling therefore covers roughly ages 6 to 15, taking in both primary and lower secondary stages.

Early childhood education caters for children aged 3 to 5 and encompasses preschools and kindergartens designed to support cognitive, social, and emotional development. Although attendance at this stage is not compulsory, places are freely available at government schools. This phase broadly corresponds to nursery and reception provision as understood in many other national systems.

Children between the ages of 6 and 12 attend primary school, known in Thai as Prathom, after which they move into secondary school, called Matthayom. Secondary education spans six years in total, though only the first three years are obligatory. The full framework of basic education follows a 6-3-3 structure: six years of primary school (Prathom 1 to 6), three years of lower secondary (Matthayom 1 to 3), and three years of upper secondary (Matthayom 4 to 6). This configuration mirrors systems used in Japan, South Korea, and the United States.

Upon completing Grade 9 (Matthayom 3), students may either progress to upper secondary education on a university-preparatory pathway or transfer to a vocational programme. Upper secondary (Grades 10 to 12) offers a choice between a general academic track — oriented towards university entry — and a vocational track concentrating on industry-specific skills and technical training.

Three years of pre-school and three years of upper secondary education are offered free of charge even though they fall outside the compulsory range. In effect, state schooling is publicly funded and accessible from age 3 through to 18, with only the 6-to-15 window being legally mandated.

What types of schools are available in Thailand?

Thai schooling is organised across three principal sectors: government (public), private, and international schools. These categories differ substantially in how they are funded, what language they teach in, how much they cost, and what educational priorities they pursue.

Government (state) schools are run and financed by the Ministry of Education. Basic education is compulsory for all Thai citizens and is provided without charge in these institutions. The government has taken active steps to broaden access, particularly in rural and economically disadvantaged communities. Government schools follow the national curriculum, conduct teaching primarily in Thai, and represent the most widely available schooling option throughout the country.

Private schools function alongside the state sector and are permitted to charge tuition. They fall under the regulatory authority of the Office of the Private Education Commission and are required to follow the national curriculum, though they frequently benefit from greater resources, reduced class sizes, and enhanced provision for foreign language learning. A number of private schools in Thailand are faith-based — commonly Buddhist or Catholic — reflecting the country’s deep religious traditions.

International schools are independently operated institutions serving primarily expatriate communities and Thai families who seek an internationally oriented education. They must comply with a framework of requirements set by the Ministry of Education, covering areas such as ownership, premises, classroom-to-student ratios, and educational support facilities. Within one year of opening, elementary and secondary international schools are required to seek accreditation from an internationally recognised body approved by the Office of the Private Education Commission, with full accreditation to be secured within six years.

Vocational education forms another important strand of the Thai system, equipping students with applied skills suited to particular careers and industries. Vocational colleges and institutes operate at both secondary and higher education levels, providing an alternative pathway for those who prefer practical, skills-focused training to a conventional academic route — similar in function to TAFE institutions in Australia or Further Education colleges in the United Kingdom.

What curriculum and qualifications do schools in Thailand follow?

Thailand operates a centralised national curriculum that defines educational standards and learning objectives across all levels of schooling. It draws together academic subjects, moral and ethical education, physical education, and extracurricular activities. Core areas of study include the Thai language, mathematics, science, social studies, and foreign languages.

A distinctive element of Thailand’s national curriculum is its integration of the “philosophy of sufficiency economy,” a framework rooted in the teachings of King Bhumibol Adulyadej and built around the principles of moderation, reasonableness, and self-reliance. This gives Thai state education a cultural dimension not present in most other national systems.

To earn a high school diploma, upper secondary students must sit the Ordinary National Educational Test (O-NET), a nationally standardised set of examinations assessing knowledge and competency across core subjects. The O-NET functions broadly like a school-leaving qualification, though its standing with foreign institutions varies. Thai university admissions generally draw on results from the Thai University Central Admission System (TCAS), rather than relying solely on O-NET scores.

The Thailand Qualification Framework (TQF) was introduced to standardise the recognition of educational credentials, taking inspiration from equivalent frameworks in the United Kingdom and Australia. Its purpose is to make Thai qualifications more readily understood in an international context, though families who anticipate re-entering another country’s education system mid-journey should check how qualifications will be recognised with relevant institutions in that country.

International schools in Thailand offer a diverse array of curricula. The National Curriculum of England — commonly called the British curriculum — is among the most widely used in Thai international schools and is recognised globally. American curriculum schools award US high school diplomas, often incorporating Advanced Placement (AP) options. Certain institutions, including International School Bangkok, hold International Baccalaureate (IB) accreditation and offer the IB Diploma Programme, a qualification accepted by universities around the world. The French Lycée in Bangkok delivers the French national curriculum, including the Baccalauréat, for families tied to that system.

What are typical school hours and holidays in Thailand?

State schools in Thailand generally operate from around 8:00 am until approximately 3:30–4:00 pm, Monday to Friday. The school day typically begins with a morning assembly, followed by structured lessons and a break at midday. School uniforms are obligatory in all government schools and the vast majority of private institutions — a firmly established cultural expectation in Thai education at every level.

The Thai state school year runs from May to March for primary and middle school pupils, while secondary schools begin approximately one month later. In practical terms, the academic year opens in mid-May and closes in late March, with a lengthy summer break running from March through May and a shorter recess in October. Families arriving from countries that follow a September-to-July calendar may find this schedule disorienting, and children joining partway through a year from a different system may experience some disruption.

At international schools, the academic year runs from August through to June, typically divided into three terms or two semesters in line with northern hemisphere conventions. This alignment makes transitions between international schools in Thailand and equivalent institutions in other countries considerably more straightforward than moving between state systems.

National public holidays — including Thai New Year (Songkran) in April and the King’s birthday — result in school closures across both state and international sectors, though international schools may observe these dates slightly differently in terms of their calendar arrangements. Families should always consult each school’s published calendar for precise term and holiday dates, as these can differ between school types and geographic locations.

How do you enrol a child in school in Thailand?

The enrolment process differs considerably depending on whether you are applying to a state or international school. For government schools, enrolment is handled through the local district education office or directly with the school itself. Families should make contact well ahead of the May start of the school year.

1. Gather required documents. Documents commonly required for state school enrolment include the child’s birth certificate, evidence of residence in Thailand (such as a tenancy agreement or utility bill), the child’s passport and visa papers, vaccination records, and any academic reports or transcripts from previous schools. Thai nationals are additionally required to provide a house registration document (Tabien Baan).
2. Contact your local district education office. State school enrolment falls under the jurisdiction of the district education office, which operates within the framework of the Office of the Basic Education Commission (OBEC). Visit the OBEC website or speak directly with the nearest school to verify current requirements and admission timings.
3. Submit an application to the school. For private or international schools, approach the admissions office directly. Given the transient nature of internationally mobile families, international schools in Thailand do not generally operate fixed intake windows — most accept applications on a rolling basis throughout the year, subject to place availability.
4. Attend an assessment or interview (if required). Many international schools include an informal assessment or interview in their admissions process to identify the appropriate year group for the child and to flag any language or learning support requirements.
5. Pay fees and complete registration. Once a place has been offered, families must pay registration and enrolment fees — which can be substantial at international schools — and finalise all administrative paperwork.
6. Arrange language support if needed. If your child does not yet speak Thai, raise the question of English Language Learner (ELL) or other language support provision with the school at this stage.

The most sought-after international schools in Bangkok frequently maintain waiting lists, particularly for younger year groups. Families preparing to relocate to Thailand are strongly encouraged to begin researching schools and submitting enquiries at least 6 to 12 months before their planned arrival. For official guidance on state school admissions, refer to the Thailand Ministry of Education and the Office of the Basic Education Commission (OBEC).

What international schools are available in Thailand?

Thailand currently has 248 international schools in total, with 121 located in Bangkok and the remaining 127 distributed across provincial areas. This makes Bangkok one of the most richly supplied cities in Southeast Asia for families seeking an internationally accredited education. Around 90 of the most well-established international schools are in or around the capital, with others spread throughout the regions.

The past 15 years have seen a notable surge in international school openings in Thailand, with prestigious British school brands including Harrow, Shrewsbury, Rugby, Wellington, and King’s College Wimbledon all establishing campuses in Bangkok. American curriculum schools, IB World Schools, and institutions offering the French Baccalauréat are also strongly represented. Beyond Bangkok, cities such as Chiang Mai and Phuket host international schools that often charge comparatively lower tuition fees.

Fee levels span a wide range. Annual tuition at international schools in Thailand can fall anywhere between approximately 150,000 baht and 900,000 baht — and at the most prominent Bangkok schools, fees climb higher still. Shrewsbury International School Bangkok charges approximately 1,109,400 baht per year, while International School Bangkok is approximately 1,075,000 baht per year (as of 2024; parents should confirm current figures directly with each school). Beyond tuition, families should also budget for application and registration fees — commonly USD 1,000–3,000 — as well as uniforms and supplies, which typically run to USD 500–1,500 per year.

Approximately 46 per cent of the student body at international schools across Thailand consists of Thai nationals, reflecting the genuinely diverse communities these schools serve. Bangkok’s standing as a regional financial centre means a substantial portion of the international student population comes from Asian expatriate families — particularly from Japan, China, India, and South Korea — attracted by internationally portable curricula and a broad approach to education.

To locate accredited international schools, the Council of International Schools (CIS) and the International Schools Consultancy (ISC) both maintain searchable databases. The International Baccalaureate Organisation also provides a school-finder tool for IB-authorised institutions in Thailand.

What higher education options are available in Thailand?

Thailand’s higher education sector encompasses universities, colleges, and vocational institutions. Universities provide bachelor’s, master’s, and doctoral programmes spanning a broad range of disciplines, while vocational institutions deliver specialised training designed to build practical competencies for particular industries.

Both public and private higher education institutions are regulated by the Ministry of Education and offer programmes across fields including arts, medicine, the humanities, and information technology. Thailand’s oldest and most prestigious university is Chulalongkorn University, established in 1917, which draws many of the country’s top-performing students and commands a respected international profile. Other highly regarded universities include Mahidol University, Thammasat University, and Kasetsart University.

Thailand’s higher education landscape is characterised by a diverse mix of public and private institutions, several of which enjoy international recognition. The government has placed strong emphasis on research and innovation as tools for improving the global standing of Thai universities. One example of this commitment is the Thai and UK World Class University Consortium, which brings together seven Thai universities and 14 UK university partners across 15 collaborative research projects.

Much of the architecture of Thailand’s contemporary higher education system draws on the American model, including degree structures, credit frameworks, and the inclusion of general education requirements within undergraduate programmes. International students may apply to Thai universities, though tuition fees, entry criteria, and language of instruction differ considerably between institutions and courses. Fees for non-Thai students are generally higher than those for domestic students. Prospective students should consult individual institutions directly for up-to-date fee schedules, which change regularly. The Ministry of Higher Education, Science, Research and Innovation (MHESI) is the government body with overarching responsibility for the university sector.

Thai domestic students gain entry to universities through the Thai University Central Admission System (TCAS), which incorporates national test results alongside institution-specific examinations. International applicants are generally assessed through a separate admissions process and should liaise directly with their chosen university for specific guidance.

What should expat parents know about language of instruction in Thailand?

Government schools in Thailand conduct all instruction in the Thai language. For families whose children do not speak Thai, this is a significant practical concern. Unlike some countries where state schools routinely offer bilingual or immersion programmes, Thai government schools are not generally set up to provide dedicated support for newly arrived students who lack Thai language skills. There is no formal second-language learner support programme comparable to those operating in, for instance, Luxembourg or Canada’s public school systems.

English language learning has been gaining greater prominence in recent years, with efforts made to encourage bilingualism and raise English proficiency. Nevertheless, English ability within the state school sector remains low overall. Thailand has consistently ranked near the bottom of global English proficiency indices — in a recent IMD World Competitiveness Yearbook, it placed 54th out of 56 countries. For children arriving in state schools without any knowledge of Thai, the experience of total immersion will be demanding, and a meaningful adjustment period — typically somewhere between 12 and 18 months — should be anticipated before a child can participate fully in academic lessons.

Younger children, particularly those under the age of 8, tend to pick up new languages far more quickly than older learners. Families relocating with very young children may therefore find a state school transition more manageable. For older children — particularly those of secondary school age — the disruption to academic progress is more pronounced, and an international or bilingual school is likely to serve them better.

International schools in Thailand operate primarily in English. Most offer English Language Learner (ELL) or English as an Additional Language (EAL) support for students who join without full English fluency. British curriculum schools, American schools, IB World Schools, and other internationally oriented institutions similarly teach in English with varying levels of language assistance available. The French Lycée in Bangkok, as previously noted, teaches in French and serves families within that framework.

Families who anticipate returning to their home country’s education system within a few years should consider language of instruction carefully. A child schooled entirely in Thai may encounter difficulties readjusting to another system on return, whereas international schools offer a more transferable academic experience and smoother re-entry into global curricula.

What financial support or subsidies are available for education in Thailand?

The Thai government, through the Ministry of Education, funds schooling from pre-primary through to senior secondary level. Free basic education up to age 15 is a constitutional right, covering six years of primary and three years of lower secondary schooling. Beyond this, three years of pre-school provision and three years of upper secondary education are also available at no charge, even though attendance at these stages is not legally required.

This free schooling entitlement applies to all children enrolled in state schools, irrespective of nationality — meaning children of expatriate residents are in principle able to access government schools without paying tuition fees (as of 2025). That said, families should be aware that even in state schools, additional costs for items such as uniforms, textbooks, stationery, and activity fees are common. While the policy of free basic education has expanded access to schooling broadly, persistent poverty in many parts of the country means that ancillary costs continue to place education out of reach for some lower-income households.

No government subsidies exist specifically to help expatriate families meet international school fees. The full cost of an international school education is borne entirely by parents. That said, many multinational employers operating in Thailand include an education allowance as part of their expatriate remuneration packages, so it is worth raising this during any relocation or employment negotiation.

Thailand does not currently have a publicly funded voucher system or tax relief mechanism for private or international school fees equivalent to those in place in some other countries. For the most current information on any available financial assistance, scholarship schemes — some international schools offer a limited number of bursaries — or changes to state school funding policy, consult the Thailand Ministry of Education and speak directly with individual schools and your local district education office.

Frequently asked questions about education in Thailand

Can my child attend a Thai state school if we are not Thai citizens?

Yes. Government schools in Thailand are open to all children living in the country, regardless of their nationality. The Thai constitution guarantees free basic education, and in practice the children of foreign residents are permitted to enrol in state schools. The most significant practical obstacle is language, since all classroom instruction is delivered in Thai. This route tends to work best for younger children or those who already have some familiarity with the language. Contact your local district education office or the Office of the Basic Education Commission (OBEC) to establish the current enrolment procedures in your specific area.

How long are waiting lists for international schools in Bangkok?

At the most popular international schools — particularly those operating from kindergarten all the way through to Grade 12 — families may face waiting periods of six months to more than a year, most commonly for the youngest year groups. Families intending to move to Bangkok are well advised to begin researching schools and lodging applications a minimum of 12 months before their target start date. Some schools operate rolling intake and can accept mid-year entrants when vacancies arise, but this cannot be counted upon at schools where demand consistently exceeds supply.

Will my child’s qualifications from Thailand be recognised abroad?

The answer depends largely on which sector your child attends. Certificates earned through the Thai state system — such as the O-NET diploma — have limited international recognition and would typically need to be assessed by a national qualifications authority before being used for university entry or further study overseas. In contrast, qualifications such as the IB Diploma, Cambridge IGCSE and A-levels, or an accredited US high school diploma carry broad recognition at universities worldwide. Families who may eventually need to move on to another country’s education system should consider from the outset which qualifications will travel best.

Are there bilingual schools in Thailand?

Yes. A number of private schools in Thailand offer bilingual programmes that deliver core subjects in both Thai and English. These institutions — sometimes referred to as “bilingual schools” or “EP” (English Programme) schools — occupy a middle ground between the standard state system and fully international schools in terms of both cost and curriculum. They can be a sensible choice for families who want their children to develop Thai language skills alongside solid English-medium academic instruction. Fees differ from school to school; prospective families should contact individual institutions for up-to-date figures.

Can expats study at Thai universities?

Yes, Thai universities welcome applications from international students. Many institutions offer degree programmes taught in English at undergraduate and postgraduate level, with particularly strong provision in business, engineering, medicine, and the arts. Entry requirements and fee structures for international applicants differ from those that apply to Thai nationals, so it is important to contact your chosen university directly for current admission criteria and tuition costs. The Ministry of Higher Education, Science, Research and Innovation (MHESI) has overall responsibility for Thailand’s university sector.

What childcare options are available for children under 3?

For children below the standard pre-school entry age of 3, families can choose from private nurseries, daycare centres, or home-based arrangements involving a nanny or au pair. The quality and cost of private nurseries varies widely, with the broadest range of options found in Bangkok. Many international schools offer early years or pre-kindergarten places for children from age 2 or 3. Unlike systems in Scandinavia or France, Thailand has no universal state-funded childcare for children under 3, meaning these arrangements are entirely privately organised and funded.

What happens to my child’s education if we move to a different region of Thailand?

Relocation within Thailand — say, from Bangkok to Chiang Mai or Phuket — means state school enrolment will be handled through the district education office serving your new area. For international schooling, the selection of available institutions is narrower outside the capital, though Chiang Mai, Phuket, Pattaya, and Hua Hin each have established international schools. Schools outside Bangkok generally charge lower fees than their Bangkok counterparts, and many follow the same recognised curricula — British, American, or IB. Always contact schools directly to check current availability and the steps required for admission.

Is there support in schools for children with special educational needs (SEN)?

The level of provision for children with special educational needs varies significantly between schools. Most Thai state schools have limited specialist SEN infrastructure, although government policy is oriented towards inclusive education. International schools typically offer stronger SEN support, including dedicated learning support staff, referrals to occupational therapists, and Individual Education Plans (IEPs) — though the breadth and depth of this provision differs between schools. Families with children who have identified additional needs should have detailed conversations with prospective schools before committing to enrolment, and should clarify which specialist services are covered within standard fees and which may incur separate charges.
