Since 2001, the United States has significantly increased investments in civilian as well as military biodefense activities. These activities vary from select agent research and engaging the scientific community on responsible conduct and biosafety training to threat characterization to bioterrorism and public health preparedness. Building and maintaining a complementary and cooperative workforce among the various biodefense activities requires that the needs of each are assessed and training programs are developed to address those needs, standard curricula and evaluation criteria are developed, and the education programs are sustained. This article provides a brief overview of current biodefense training programs followed by a case study evaluating the educational requirements of the workforce that is responsible for determining whether emerging biotechnologies pose threats to national security. Developing the workforce to accurately assess biological threat, especially for emerging biotechnologies, requires cross‐disciplinary training in the life sciences, epidemiology and outbreak response, and cultural anthropology and theology. The case study uses synthetic biology, a rapidly advancing biotechnology, as a model for evaluating the skills of the workforce needed to accurately assess the potential national and international security risks of the technology.
