In the 10 years I've been here I've heard of most of the bad schools, NDI ranks up there near the top, as most Franchise centers seem to. I will disagree that you need any equipment at all to teach English, except maybe a black board. NDI has all sorts of computers and other nonsense, and they still stink. The best English teacher were often Monks and priests who converted heathen masses in foreign countries, and they did so with out fancy equipment, and they did so better than English teachers these days. What you need to people educated in sound teaching principles and who are simply "educated" and skilled at their work.
