From 2001-2007, DoD deployed more than 434,000 reservists in Afghanistan and Iraq. While on active duty, reservists may be unable to take the required professional dev¿t. courses or periodic tests needed to retain their professional currency in fields such as accounting or software engin. This report examines the no. and type of professional or other licensure or certification require. that may be adversely affected by extended periods of active duty, and identifies options that would provide relief. The objectives were to examine: (1) DoD¿s efforts to identify the extent to which active duty service has had an impact on the ability of reservists to maintain professional licenses or certifications in their civilian careers; and (2) relief options for addressing these issues.
