I spent a little of last week meeting in Utah on their performance based teacher certification program - the ARL. They are really pleased with the people that become teachers through that program. There are no seat time requirements or minimum hours required. You demonstrate you have the knowledge, through a program like ABCTE, and you can become a teacher. Meanwhile, down in Louisiana, they created an alternative program that requires enough university based credits to be one couse shy of a Master's.
Swift and Able has a great blogpost summarizing the recent arguments on teacher preparation and letting us know that ed schools have not changed in a hundred years.
Even with pressure coming from Secretary Arne Duncan, I don't think they will change now unless they get enough competition from groups like ABCTE, that they realize they have no choice.
