Institution-certified copy
The school or university issues an English version or certifies the copy with an authorised signature and its seal.
Authority: The issuing educational institution
Thai degrees and transcripts usually pass through three layers in sequence. First the institution certifies the copy or issues an English version. Second, the supervising ministry verifies it when the destination asks for that. Third, the Department of Consular Affairs legalises the signature and seal of the signatory. If the destination is outside the Apostille Convention, its embassy may add one further layer.

| Translation required | Not needed if the institution issues an English version | As the authority specifies case by case | A translation is required when the source is in Thai |
| Which destinations | Domestic use or as the base document | Destinations with strict credential checks, e.g. professional bodies | Nearly all overseas destinations |
