CIEE is legit.

After a reasonable fee of $1000, and 11 weeks of power points, discussion posts, quizzes, and useful weekly assignments (including the production of lesson plans for the future), you gain access to the world! I am now eligible to teach in South Korea, and I feel well-equipped to do so! A lot of valuable information is given in this course, and whatever is not explicitly written you can find on your own using the provided links to legitimate educational resources.

You do have to find an institution and/or people to tutor for Practicum hours on your own, but CIEE provides advice and a tutor--a real person to communicate with via video calling. CIEE also provided me with a letter as proof of enrollment during my application process for teaching abroad. All you have to do is email these people and they'll get right back to you.

The tech stuff is easy to figure out if you've been around computers, the coursework isn't at all over the head of anyone who has successfully done at least some college units, and if you're a slow reader, I'd carve 20 hours per week out of your schedule to complete the work. Through CIEE, it's not at all a grueling process to earn your TEFL certificate. :)
