How to Say “Good job” in Thai
เก่งมาก
kèng mâak
Good job
ค่ะ (khâ) and ครับ (khráp) are polite particles — they depend on the speaker's gender, not the listener's.
Word by word
When to use it
This is a warm, natural way to praise someone's performance or ability — teachers say it to students, and parents to children. Just เก่ง (kèng) on its own works perfectly too. ทำได้ดี (tham-dâay dii) — (You) did it well — is another option.
Why you've seen it spelled differently
You may have seen เก่งมาก written as: geng mak, keng maak, keng mak.
There is no single standard for writing Thai in the Roman alphabet — phrasebooks, road signs, and tourist guides each follow a different system, and many just invent their own spellings. The romanization on this page uses a consistent IPA-based system that marks all five tones and distinguishes short from long vowels. The same word always gets the same spelling.
