Thai Test for Non-Native Speakers (CU-TFL)

Chulalongkorn University Thai Proficiency Test for Non-Native Speakers (CU-TFL) is a standardized test developed by the Sirindhorn Thai Language Institute, Chulalongkorn University. It assesses the Thai language proficiency of individuals who speak Thai as a foreign language. The test covers four skills: listening, reading, writing, and speaking. Test-takers can choose to take all skills together or select individual skills for testing.
✨Purpose of the CU-TFL Test
The CU-TFL test can be used for various purposes, such as applying for admission to Thai educational institutions or for job opportunities at Thai companies, both in Thailand and abroad. Additionally, institutions teaching Thai to foreigners may use CU-TFL results to adjust their teaching curricula, helping to enhance the language skills of their students.

The CU-TFL test evaluates the following skills:
Listening
Reading
Writing
Speaking

The ability to write short, simple sentences

✨Thai Language Test Results
Results are reported based on the level of proficiency in each skill, not on a pass/fail basis. Test-takers receive scores that indicate their proficiency level, which is then converted into performance levels.
✨Proficiency Levels
The CU-TFL test scores are divided into five levels for each skill (listening, reading, writing, and speaking):
Chula Distinguished (Outstanding)
Chula Superior (Very Good)
Chula Advanced (Good)
Chula Intermediate (Intermediate)
Chula Novice (Basic)
Additionally, a "Plus" rating can be awarded for any level. For example, if a test-taker receives a score of Advanced Plus, it indicates that they perform above the base level of "Advanced" but have not yet reached the "Superior" level.
The CU-TFL test provides a comprehensive assessment of Thai language proficiency, making it a valuable tool for anyone looking to study, work, or improve their Thai language skills. The test offers flexibility, allowing participants to test all skills or focus on specific areas based on their needs.
