Teaching English as a Foreign Language (TEFL) course with i to i?

Yes, for an entry level job an online certificate is fine. Check out http://teflcoursereview.com/ which has former students rating the courses they've taken.

CELTA is far better than TEFL in terms of a teaching certificate. Firstly, it is standardised and therefore welcomed by many more institutions. Secondly, it takes place over an intensive month long course that gets you in front of a class from the very first day. This is ideal as you have to see how you cope in front of the students before you know what you are doing. Most universities and many language schools offer these courses throughout Europe. I took mine at Bath Spa University and I now teach in the English department of a Polish University so it worked for me. CELTA will give you confidence because it will show you that you can do it and prepare you for most eventualities by giving you as mmuchteaching experience as possible in a cconstructiveand educational environment.
