Gemma,
That is an excellent question. The correct answer would depend on the specific circumstances. If you have an official foreign transcript, I suggest using a reputable document translation service to obtain a documented translation. If your school is not required to submit instructor applications to the TWC CSC, you should consider contacting them for input prior to utilizing the instructor. You could also follow the variance procedures for assurance and documentation that the instructor is competent.
