If you have never taught before, I strongly urge taking the CELTA course. I took it in Siam Square, Bangkok, Thailand and thought the instruction was fantastic. I came into the course with several years teaching experience, but still gained valuable hands on techniques I'd never learned. I owed it to myself and my students after teaching so long without any formal training (B.A in Literature)to get some professional development. The CELTA course is internationally recognized and well worth the time and money. Good luck!
