This recommended practice discusses policy and procedural guidelines for the implementation and oversight of background screening investigations. It includes criteria for selection of security background screening investigation methodologies based on different factors, including transit agency size, regulatory requirements, resource intensity (cost) and threat conditions. This recommended practice includes a summary of the relevant provisions in the “Implementing Recommendations of the 9/11 Commission Act of 2007” (Public Law 110-53), as well as Federal Transit Administration and Transportation Security Administration guidelines and recommendations for background checks. It is recommended that transit agencies conduct security background screening investigations consistent with these federal guidelines. Specifically, transit agencies should use the federally approved list of disqualifying criminal offenses when conducting background checks and should ensure that an appropriate redress process is available.
