Hi,
It would all depend. Hands down, a master's degree far outweighs a CELTA, DELTA, or any other TESOL, TEFL, etc. certification. Just make sure:
-the place you do it from is accredited
-the program has been around for a while
-they have asynchronous-based discussions
and a few others I can't think of off the top of my head.
Me.
