Earlier this month, the National Security Personnel System (NSPS) Program Executive Office issued guidance on how vacancies should be filled while it transitions personnel out of NSPS. (The FY2010 Defense Authorization Act repealed the authority for the NSPS.) The transition period is between October 28, 2009 and January 1, 2012. In all cases, transitions from the NSPS to a General Schedule (GS) or other statutory pay system are to result in no pay loss. As NSPS jobs become vacant, DoD will begin to appoint replacements to non-NSPS statutory pay systems. However, federal employees union representatives have criticized the plan because it would allow the categorizing of new hires under NSPS until March 2010. DoD will continue to issue transition guidance as appropriate. You can follow them on the NSPS website.
