Reports & Testimonies

  • GAO’s recommendations database contains report recommendations that still need to be addressed.

    GAO’s recommendations help congressional and agency leaders prepare for appropriations and oversight activities, as well as help improve government operations. Recommendations remain open until they are designated as Closed-implemented or Closed-not implemented. You can explore open recommendations by searching or browsing.

    GAO's priority recommendations are those that we believe warrant priority attention. We sent letters to the heads of key departments and agencies, urging them to continue focusing on these issues. These recommendations are labeled as such. You can find priority recommendations by searching or browsing our open recommendations below, or through our mobile app.

    2 open recommendations
    Recommendation: The Administrator of TSA should explore and pursue methods to assess the deterrent effect of TSA's passenger aviation security countermeasures; such an effort should identify FAMS—a countermeasure with a focus on deterring threats—as a top priority to address. (Recommendation 1)

    Agency: Department of Homeland Security: Transportation Security Administration
    Status: Open

    Comments: DHS concurred with this recommendation and said it would take steps to implement it. When we confirm what actions TSA has taken in response to this recommendation, we will provide updated information.
    Recommendation: The Administrator of TSA should systematically evaluate the potential cost and effectiveness tradeoffs across countermeasures, as TSA improves the reliability and extent of its information on the effectiveness of aviation security countermeasures. (Recommendation 2)

    Agency: Department of Homeland Security: Transportation Security Administration
    Status: Open

    Comments: DHS concurred with this recommendation and in its September 2017 response to our report, DHS stated that TSA will continue efforts to improve both its analysis of information related to security effectiveness and its cost information, leading to better informed cost-benefit decisions for individual countermeasures. To address the intent of our recommendation, TSA will need to evaluate the costs and effectiveness of individual aviation security countermeasures and then use this information to systematically evaluate the potential cost and effectiveness tradeoffs across countermeasures. When we confirm what actions TSA has taken in response to this recommendation, we will provide updated information.
