When my students ask about Teach for America, I try to make it clear to them that it is not the mission of TFA to develop career teachers. Instead, TFA is trying to develop future leaders in business, law, medicine, politics, etc., who will have the benefit of teaching experience. That's a very different thing, and headlines like this one should not be a surprise.
