Transition courses won't just be phased into refreshers. If 2012 is not your refresher year you'll have to take an independent transition course. The course is needed because there is a slight change in scope of practice, there are new things to cover education wise and some things are being removed. Also if your lucky enough to be taking one of the nationally recognized critical care courses such as UMBC's CCEMT-P or Creighton Universities program those will count towards your transition course as the material they present meets and far exceeds that needed by national registry to transition into the new role.
