ITTT Online TEFL

A good option for someone without a lot of time to devote to gaining a TEFL certification, but not wonderful if you want an in-depth instruction into what teaching English actually looks like. But it's definitely a good start, and is very affordable and flexible. At the end of the course, you create lesson plans and receive critiques, which is helpful. You also get a flexible stretch of time in which to complete the course, which is also quite nice if you have other things going on in your life.
