CBP revised its training program for newly hired CBP officers in accordance with its own training development standards. Consistent with these standards, CBP convened a team of subject-matter experts to identify and rank the tasks that new CBP officers are expected to perform. As a result, the new curriculum was designed to produce a professional law enforcement officer capable of protecting the homeland from terrorist, criminal, biological and agricultural threats. In addition, the curriculum stated that the CBP officer is to draw conclusions and take appropriate action to identify behavioral indicators displayed by criminals, effectively interview travelers to identify potential threats, identify fraudulent documents, and use technology in support of the inspection process. CBP has taken some steps to identify and address the training needs of its incumbent CBP officers, but could do more to ensure that these officers are fully trained. GAO examined CBP's results of covert tests conducted over more than 2 years and found significant weaknesses in the CBP inspection process at the ports of entry that were tested. In response to these tests, CBP developed a "Back to Basics" course in March 2010 for incumbent officers but has no plans to evaluate the effectiveness of the training. Moreover, CBP has not conducted an analysis of all the possible causes or systemic issues that may be contributing to the test results. Further evaluation of the training and causes underlying covert test results could help inform CBP about whether the training is sufficient to address the weaknesses identified by the covert tests or if adjustments are needed. In addition, CBP offices are responsible for recording their employees' training records; however, CBP does not have a policy that assigns responsibility to port management to ensure that their staff enter data into its training records system completely and accurately. A policy outlining the roles and responsibilities of offices and positions for training could help clarify which offices and positions are responsible for identifying and addressing training needs and for holding these offices accountable for their responsibilities. Moreover, CBP currently does not have reliable training completion records to ensure CBP officers received required training or other training relevant to their assigned duties. Based on GAO's analysis of training records, more than 4,000 customs officers have not completed the immigration fundamentals, immigration law, and agricultural fundamentals courses, although they were required to complete them during a cross-training program. According to CBP, the training completion records are incomplete, and it is unlikely that the officers did not complete the required cross-training. Nevertheless, without reliable training records; CBP cannot provide reasonable assurance that all customs officers completed the required cross-training. Further, CBP has not conducted a needs assessment that would identify any gaps between identified critical skills and incumbent officers' current skills and competencies. A needs assessment could enhance CBP's ability to ensure its workforce is training to meet its mission.
