I am getting TEFL certified online with a combo onsite class. The time onsite is one to two weeks. I wonder if that is enough classroom experience. I want to find something about how this went with other instructors. I am volunteering here in Texas with immigrants, so I feel I will have more classroom experience than some new instructors, but how much is enough?

I am responding to a somewhat related post, because I haven't been able to figure out how to start my own thread.

I am looking at a certification from this organization:

Ever heard of it? Any advice would be helpful.
