Thai Proficiency Tests for Foreigners Compared: CU-TFL, MU-Thai, TPA

CU-TFL, the MU-Thai Test and the TPA Thai test: who runs them, what they test, and how to choose.

If you need to prove your Thai for a university, an employer or yourself, there are a few established tests for non-native speakers. They differ in who runs them, which skills they cover and how results are reported. The table below sums up what each organiser publishes. Dates, fees and formats change, so confirm the details with the organiser before you register.

CU-TFL (Chulalongkorn University)

The CU-TFL (Chulalongkorn University Proficiency Test of Thai as a Foreign Language) is run by the Sirindhorn Thai Language Institute. It covers listening, reading, writing and speaking, and gives a level for each skill, from Novice to Distinguished, so you can take only the sections you need. Besides Bangkok, it is held with partner universities abroad: the University of Hong Kong held a session on 22 August 2026, and Taiwanese universities have co-hosted it for years. It is often named in university requirements: Mahidol's graduate school, for example, listed CU-TFL at Advanced level in its 2021 guidelines.

The reading section is multiple choice with four options (ก ข ค ง). Short practical texts come first, then news and opinion passages that grow to more than a page. Try the format with our free CU-TFL reading practice test.

MU-Thai Test (Mahidol University)

Mahidol University's Research Institute for Languages and Cultures of Asia (RILCA) runs the MU-Thai Test, which assesses all four skills. It is aimed at foreigners who plan to study, live or work in Thailand, and at employers who need to check a candidate's Thai. RILCA announces sessions individually; a session on 20 December 2025 had a fee of 1,500 baht. The format and level scale are not published in detail, so ask RILCA before you book.

TPA Thai Language Proficiency Test

The Technology Promotion Association (Thailand-Japan) has run its Thai test since 2008 and uses a five-level scale (T1 Beginner to T5 Proficient) with no pass or fail. It covers writing, reading and listening, but not speaking. The test has 95 questions worth 100 points, all in Thai script: writing and reading together take 90 minutes, then listening takes 30 minutes. It is held in Bangkok twice a year, on the first Sunday of February and of October. Its T3 level is described as understanding newspaper and magazine articles on general topics, and T4 as understanding complex economic, political and social content in the media.

Other tests

The Office of the Basic Education Commission (Ministry of Education) also runs a Thai language test for foreigners, with results described in terms of Thai school levels; Mahidol's 2021 guidelines accepted it at lower-secondary level. For speaking only, some employers and universities accept an oral proficiency interview. Ask the institution that needs your result which tests it accepts.

How to choose

For a university or a job, take the test your university, programme or employer names. When none is named, the CU-TFL is the most widely known.
If you only need certain skills, the CU-TFL lets you take individual sections, and the TPA test leaves out speaking.
If you live outside Thailand, look for a CU-TFL session with a partner university near you.

Preparing for the reading sections

The higher levels of every test expect you to read formal written Thai: news reports, announcements and opinion pieces. That means news vocabulary, long sentences and quick reading. Our guide to reading Thai news covers the key patterns, the Thai news vocabulary lists group the words by topic, and every Advanced Thai Reading lesson gives you a real news passage with every sentence explained.

Questions

Which Thai proficiency test is most widely recognised?

The CU-TFL from Chulalongkorn University is widely described as the most popular Thai proficiency test, and universities often name it. Check what your university, employer or programme asks for before you book, because requirements differ.

Do Thai universities require a Thai test?

Some programmes taught in Thai ask foreign students for proof of Thai. Requirements are set by each university and often by each programme. Mahidol University, for example, used to name CU-TFL at Advanced level and now leaves the requirement to each programme.

Which test should I take for reading?

All of these tests include reading. The CU-TFL and the TPA test both build up to long passages in formal written Thai of the kind found in newspapers, so news reading is the best preparation for either.
