As of Oct. 1, 2007, the Transportation Security Administration (TSA) requires United States airports to screen individuals for security threats before issuing SIDA badges. The information is run through the Terrorist Screening Database to assess potential security risks.
Airports perform detailed background checks of all employees and others before authorizing access to secured areas. Background checks include fingerprinting and in-depth criminal history queries. Individuals found guilty of any disqualifying crimes are denied SIDA clearance.
Disqualifying crimes include but are not limited to murder, extortion, assault with the intent to murder, espionage, kidnapping, armed robbery, arson, distribution of a controlled substance, various transportation crimes and many felonies.
Individuals who pass prerequisite screenings are required to take a SIDA course detailing badge responsibilities and airport security. Additionally, a qualified sponsor such as an employer must refer SIDA candidates applying for a badge.
