PMI has finally announced the certification for program managers ---- the Program Management Professional or PgMP (the "sm" after the designation in the press release is for the service mark). It'll be available in early 2007.
The title is probably a good choice and has good synergy with the existing PMP designation. Of course, it's the same designation as the Program Management Plan (PgMP) from the Army Core of Engineers, so hopefully that won't cause confusion in those circles.
As I've mentioned before, the rigor of the PgMP requirements should give organizations a pretty good feeling about taking on program managers with this certification. It's based heavily on experience in the real world and feedback on results as opposed to pure knowledge.
Also, one needn't have a PMP certification to apply for PgMP certification. Here's the press release...
