My transcript is already issued in English — do I still need a NAATI translation?
No. If the institution itself issues an official English-language version, that is an original English document rather than a translation, so no translator's stamp is required.
In-depth Answer
Most Thai universities issue transcripts and graduation certificates bilingually, or will issue a dedicated English version on request.
Those bear the institution's seal and the registrar's signature, so they are originals in their own right and need no translator.
Three situations break this.
First, the institution issues Thai only — common for secondary and vocational qualifications.
Second, the 'English version' is a translation the student produced and had stamped as a certified copy, which is not an institutionally issued document.
Third, the name on the qualification is spelled differently from the passport.
The quick test: does the English document carry its own document number, institutional seal, and an authorised institutional signature?
If not, order a translation from the Thai original instead.
