I'm interested in teaching ESL at an American community college or at local university ESL program. I'm not sure if I need to go back to school for another degree or certification. I have a master's degree in Higher Education Administration and have about eight years of experience working in student affairs. Prior to this, I taught English in Japan right out of undergrad and worked as an English tutor in a university ESL program. I also did some volunteer work with English tutoring. Unfortunately, I've been out of this for 8 years.

Do you think I need to go back to school for a TESOL certification or degree or will my master's and other experience qualify me for a job?

Thanks!
Nicole
