There is no reason for it to exist--it is nothing but a parasitical organization designed to make its "investors" even more rich and at taxpayer expense.
People who have gone the route of going into teaching in midlife KNOW how treacherous it is given the rampant age discrimination that goes on in public education. People also have to realize that once they hit fifty especially, their health insurance premiums go way, way up, and that’s another incentive for districts to ditch you.
They will ditch you on the most bogus of allegations to save a few bucks. I have been there. Why deliberately become a temp only to be canned in a year or two when you can just stay in your perfectly stable job?
There is NO teacher shortage anywhere in the United States. TFA needs to be shut down.
