Currently dealing with these folks as part of getting my Thai teaching license here. School are helpful in the paperwork process, which is great. However, they apparently need a high school diploma. As a Brit, we get exam board certificates, which I assume will be fine...I hope. I am wondering if they need to be attested? I have quite a few and it would be a bit pricey, so only want to start the process if absolutely necessary. All my other degrees and certificates are good to go.

Apologies in advance for the utterly boring thread.
