The Air Force is offering courses to help more than 40,000 civilian employees to convert to the General Schedule (GS) personnel system from the current National Security Personnel System (NSPS). The courses – “Classifying Positions Under GS: A Primer for Supervisors,” and “Performance Management: A Tool To Achieve Results,” will be available on the NSPS Web site at http://www.cmps.osd.mil/nsps/. Defense Department civilian employees are required to move to the GS system by Jan. 1, 2012.
