Sample questions from the thai test
Real items from the test bank — one per level band. The full test adapts from A1 to C1.
พ่อของผม ___ ครูครับ
- 1อยู่
- 2มี
- 3เป็น
- 4คือ
Show answer
Correct: เป็น
The copula "เป็น" links a subject to a category/role/status: "พ่อเป็นครู" (Dad is a teacher). "อยู่" marks location/existence, "มี" means "have/there is", and "คือ" equates definitions ("A is (precisely) B"), not occupation.
คน ___ ยืนอยู่ตรงนั้นเป็นพี่ชายของฉัน
- 1ของ
- 2ที่
- 3กับ
- 4ให้
Show answer
Correct: ที่
A relative clause modifying a noun is introduced by "ที่" (who/which/that): "คนที่ยืนอยู่ตรงนั้น" (the person who is standing there). "ของ" is possessive, "กับ" "with", and "ให้" "for/give".
ข้อเสนอนี้มีข้อดีหลายอย่าง ___ ก็ยังมีความเสี่ยงที่ต้องพิจารณา
- 1ดังนั้น
- 2อย่างไรก็ตาม
- 3เพราะฉะนั้น
- 4นอกจากนี้
Show answer
Correct: อย่างไรก็ตาม
A formal concessive-rebuttal ("however/nevertheless") is "อย่างไรก็ตาม": it concedes the merits then introduces the counterpoint. "ดังนั้น/เพราะฉะนั้น" mean "therefore" (no contrast), and "นอกจากนี้" "moreover" (mere addition).

Methodology
This Thai grammar test contains 50 items (10 at A1, 10 at A2, 10 at B1, 10 at B2, 10 at C1), ordered from A1 to C1 and drawn from the same item bank used inside the Lenguia study-plan product.
Scoring uses a pass-threshold model: each CEFR level is "passed" when you earn roughly two-thirds of its available points, and your result is the highest level you pass consecutively starting from A1. This rewards consistent competence rather than lucky guesses. Results range from A1 to C1 (the test does not grade C2).
The items are informed by the competency descriptors of the Council of Europe CEFR framework. This is a free self-assessment: results are a reliable orientation, not a certified proficiency measurement.
The competency descriptors follow the Council of Europe CEFR framework.

Frequently asked questions
How accurate is this Thai grammar test?
It uses the same item bank and pass-threshold scoring as the placement engine inside Lenguia's study-plan product, so the CEFR estimate is consistent and repeatable. Like any online self-assessment it is an orientation, not an official certificate.
Is it really free? Do I need an account?
Yes — the full test, the result and the shareable certificate are free, with no signup. If you create an account afterwards, your result can be used to build a personalized study plan.
What levels can I get?
A1, A2, B1, B2 or C1. A level counts as reached when you earn roughly two-thirds of its points and have passed every level below it. C2 is not graded.
Can I retake the test?
Yes, as often as you like. Questions within each level are shuffled, and your latest result replaces the previous one on this device.
