The Transportation Security Clearinghouse (TSC) is a non-profit arm of the American Association of Airport Executives that operates in partnership with the Transportation Security Administration (TSA) to ensure Security Threat Assessments (STA) and Criminal History Record Checks (CHRC) are accomplished for aviation workers who require access to the secure areas of airports.
The TSC is the nation's largest civilian clearinghouse processing over 1.3 million TSA mandated Security Threat Assessments (STA) and more than half a million biometrically-based Criminal History Records Checks (CHRC) in the last year alone.
