Education in Thailand: school stages, TCAS university admission and English tests

In short\n\nThailand has a national basic education system that is run by the Ministry of Education, and a separate Ministry of Higher Education, Science, Research and Innovation that looks after universities. Most children attend school for twelve years, and the first nine of those are compulsory. Universities choose their students through a national system called TCAS, which combines school records, portfolios and national test results. This guide explains the stages, the tests that really exist and how to study for them. Rules change from year to year, so treat every detail here as a starting point and read the official announcements.\n\n## School stages\n\nYoung children can start in kindergarten, which many families treat as a gentle introduction to school life. Primary school is called Prathom and runs from Prathom 1 to Prathom 6. Lower secondary school is called Mathayom and its first three years, Mathayom 1 to 3, complete the compulsory period. Upper secondary school covers Mathayom 4 to 6. After Mathayom 3, students choose between an academic track that prepares for university and a vocational track at technical or vocational colleges. Vocational students can later continue to a higher vocational certificate or to a degree.\n\nThe national curriculum names a set of core subjects such as Thai, mathematics, science, English, social studies, health and physical education, arts, and careers and technology. Schools add their own electives and local content. Many upper secondary schools group students into programmes that emphasise science and mathematics, languages, or arts, which later shapes which tests a student takes.\n\n## National tests at school\n\nThe Ordinary National Educational Test, known as O-NET (also written ONET), is the long-running national test of school achievement. It has been taken at the end of Prathom 6, Mathayom 3 and Mathayom 6 and covers Thai, mathematics, science and English among other subjects. The way schools and universities use O-NET has changed over time, so ask a school or the testing body what applies to a given year.\n\n## University admission\n\nAdmission to Thai universities runs through TCAS, the Thai University Central Admission System. TCAS is organised in rounds. The portfolio round looks at a student's school record and achievements. The quota round is meant for students from particular areas or with particular talents. The admission round makes the largest use of national test scores. A final direct round lets universities fill the places that remain. Each university and faculty publishes its own seats, requirements and weightings, and the official portal at mytcas lists them.\n\n## The tests behind TCAS\n\nThree national tests matter for most applicants. TGAT, the Thai General Aptitude Test, measures general skills such as communication in English, logical thinking and workplace competencies. TPAT, the Thai Professional Aptitude Test, is a family of tests linked to fields such as medicine, art, engineering, architecture and teaching. The A-Level tests are subject exams in areas such as mathematics, science, social studies and languages. Please note that the A-Level inside TCAS is a Thai national subject test. It is not the same thing as the Cambridge A-Level qualification that appears elsewhere on this site, although both bear the same name. The national testing body and the higher education ministry publish the test calendar, and details can shift from one admission year to the next.\n\n## Language of instruction\n\nThai is the language of teaching in state schools, and English is taught as a foreign language from the early years. Many private and international schools teach in English and follow curricula such as Cambridge IGCSE and A-Level or the IB Diploma. Students from those schools usually apply to Thai universities through international tracks, or they apply abroad, and each university states which qualifications it accepts. The questions on this site are written in English.\n\n## Studying for TCAS\n\nA good plan starts early in Mathayom 5. First, list the programmes you want and read the requirements for each, because the required tests differ between faculties. Second, build a study calendar that gives every required test a fixed weekly slot. Third, practise the TGAT in short daily sessions, since its English communication and reasoning parts reward steady habits rather than cramming. Fourth, for the TPAT in your field and for the A-Level subjects, review the school syllabus and then solve past-style problems against a timer. Fifth, keep a notebook of mistakes and sort them into three kinds: a missing fact, a wrong method and a careless slip. Reviewing that notebook every weekend is worth more than starting a new book.\n\nPortfolio applicants should also prepare early. Keep records of projects, competitions and volunteer work, and practise explaining them clearly, because interviews are common in some programmes. Remember that a plan for the later rounds protects you if an early round does not go your way.\n\n## Studying abroad\n\nMany Thai students also look at overseas universities. IELTS and TOEFL are the English tests that universities abroad most often request, and some programmes ask for the SAT. The IB Diploma and Cambridge A-Level are school qualifications that some students in Thailand take instead of the national route.\n\n## Preparing with GetMyMockTest\n\nGetMyMockTest offers free practice in English for the exams below.
