TEFL Online worked for me

Parts of this course seem simple when you read the unit material, when you get to the test at the end of the unit they make you pay better attention for subsequent units. I started with the 60 hours and then upgraded to the 120 hour after completing the 60. The advantage was having to write two lesson plans that were evaluated and both sent back for refinement. This is not a rubber stamp get your certificate program. It is more robust than that.
