The South Central Center for Public Health Preparedness (SCCPHP) is a collaboration among the schools of public health at Tulane University and the University of Alabama at Birmingham and the state health departments in Alabama, Arkansas, Louisiana, and Mississippi. The SCCPHP provides competency-based training via distant delivery methods to prepare public health workers to plan for and rapidly respond to public health threats and emergency events. This article presents the training system model used by the SCCPHP to assess, design, develop, implement, and evaluate training that is both competency driven and practice based. The SCCPHP training system model ensures a standardized process is used across public health occupations and geographic regions, while allowing for tailoring of the content to meet the specific training needs of the workforce in the respective state and local health departments. Further, the SCCPHP training system model provides evidence of the reciprocal nature between research and practice needed to advance the area of emergency preparedness training and workforce development initiatives in public health.
