"For this report, GAO was asked to assess the progress CBP has made since 2005 in (1) improving its benefit award policies for C-TPAT members, (2) addressing challenges in validating members' security practices, and (3) addressing management and staffing challenges. To perform this work, GAO analyzed a nonprobability sample of completed validations; reviewed annual, human capital, and strategic plans; and held discussions with CBP officials. […]GAO is recommending that CBP improve its electronic validation instrument, improve the validation process, enhance its records management system, and establish performance measures for improving supply chain security. CBP concurred with each of the recommendations."
