Transportation Security: Action Needed to Strengthen TSA's Security Threat Assessment Process

A letter report issued by the Government Accountability Office with an abstract that begins "The Transportation Security Administration's (TSA) Adjudication Center performance data show mixed results, and the center's performance measurement practices have limitations. The Adjudication Center relies on contractors to adjudicate security threat assessments and uses three primary measures to evaluate their performance--timeliness for completing adjudication, adjudication accuracy, and caseload status. GAO found that the Adjudication Center contractor met its timeliness and accuracy measures, but faced challenges in meeting its caseload measure. The Adjudication Center's timeliness and accuracy measures did not capture key data. According to TSA officials, the Adjudication Center's accuracy rate is based on a review of all cases where adjudicators had disqualified an applicant. However, this calculation generally does not include the accuracy rate for those applicants adjudicators had approved--which account for roughly 90 percent of the Adjudication Center's caseload. In this way, the accuracy rate provides a limited assessment of adjudicator performance. By developing an accuracy rate that includes data on both incorrectly disqualified and incorrectly approved applicants, TSA can better identify and addresses performance issues among its workforce.
