Since the early 1990s, American and International forensic science laboratories and practitioners have collaborated in Scientific Working Groups (SWGs) to improve discipline practices and build consensus standards. In 2014, the SWGs are being reorganized under the NIST Organization for Scientific Area Committees (OSAC).
As of January 2012, active SWGs included the following:
Each SWG includes scientists working within the focus field. Although a couple the above-listed SWGs have only American members, most also have international members. Federal, state or local government forensic laboratory scientists are the most common SWG members, but many SWGs also include other experts such as private laboratory scientists, academia, independent consultants, attorneys and judges.
Most SWGs have public websites with discipline-specific resources including approved and draft for comment standards, best practices guidelines and related documents.
