Actually, from what we've been told by our aministration is that OMS and Pedo will not lose their GME funding because they have hospital based components.
As of yesterday, Endo, Ortho, and Perio residencies will cost $49K annually and AEGD will cost $25K at Penn. Those students who are currently enrolled in residency programs will continue to receive GME funding for up to 3 years, or until their program is completed (whichever comes first).
Even still, it's a sound financial investment to go ahead and spend the extra money to specialize because you will make that and much more back in the long run.
