The U.S. Office of Personnel Management (OPM) plans to issue interim regulations to implement statutory changes pertaining to veterans' preference. We are making these changes in response to the Hubbard Act which broadened the category of individuals eligible for veterans' preference; and to implement the VOW (Veterans Opportunity to Work) to Hire Heroes Act of 2011 which requires Federal agencies to treat certain active duty service members as preference eligibles for purposes of competing for a position in the competitive service even though the service members have not been discharged or released from active duty and do not have a Department of Defense (DD) form 214 Certificate of Release or Discharge from Active Duty. In addition OPM is updating its regulations to reference existing requirements for the alternative ranking and selection procedure called category rating; and to add a reference to the end date of Operation Iraqi Freedom which affected veteran status and preference eligibility. This action will align OPM's regulations with the existing statute.
