teaching practice is also nice for people who have little or no experience in teaching.
I went with 100++ hours classroom training and teaching practice when I enrolled with at teflintl.com and I must say it's a pretty heavy course that I wouldn't want to do online,let alone with no practice.
there are a number of bodies out there sort of regulating the pack but I really don't know much on that. Mostly I dive into feedback from people who took the course, location of training center, any other stuff that the provider offers.
got a job fairly quickly after taking the course thanks to TEFL Intl, and I didn't take the course at same location I wanted to teach at.
(squeezed in a vacation for me and someone after the course.
