If you only read this post, you'd think the study Teach for America is referencing showed TFA teachers were heads-and-shoulders above the rest. But dig just a little further -- really, just a little -- and read the brief of the Mathematica report (http://mathematica-mpr.com/~/media/publications/pdfs/education/tfa_investing_innovation_ifbrief.pdf) and you'll find that in almost all the cases, TFA teachers performed about the same as other teachers in the study. Only in lower elementary reading did the study find students of TFA ahead of those of other teachers. TFA might brag that this study used "gold standard" research methods, but they sure didn't do a "gold standard" job of honestly interpreting the results.
