CBMS put a group together to update the Mathematical Education of Teachers document. The original MET was from 2001, and the update MET2 from 2012. I believe the committee has been named and they're busy working on updating things. One of the updates will be that they're collaborating with a group from the American Statistical Assocation (who is doing the SET documents) so they'll have some overlap between the two.
