I have no dog in this fight but it sure seems a lot of accusations are being thrown around without a lot of real evidence.

I found this on the web page.

"The TEFL International Certificate programs are among the best of their kind; excellent trainers teaching modern methodologies with input from some of the brightest minds in ESL. I highly recommend TEFL International."

Full disclosure, this was written by David Nunan but I am not him! Does that make sense? haha
