Governmental public health agencies have experienced longstanding challenges in recruiting individuals at the state and local level. Understanding civil service laws as they relate to the hiring processes is an important component of recruitment and increasing public health workforce capacity. This study presents state hiring laws and regulations governing the public health government workforce. Legal mapping techniques were employed to collect and code data on current hiring laws governing governmental public health employees across all 50 states. The review of laws included constitutions, statutes and regulations, and searches of administrative code. In 12 states, the laws do not specify civil service exam criteria or they have no mention of civil service exams in the law. Almost a third of states have laws that establish civil service exam requirements without specifying conditions for when exams must be required, or which positions allow which types of exam/criteria. Similarly, almost all of the states that have civil service exams denoted in their laws have unspecified language about whether there are exam fees. Requirements for the maintenance/use of state hiring lists are in place in 36 states and 26 states have a non-public health agency managing this process. Nearly all states (n=48, 96%) require hiring preferences for certain types of individuals, most commonly veterans (n=48, 96%) and family members of veterans (n=30, 60%). No state laws provide hiring preferences for individuals from public health fellowships or special training programs. Key findings suggest that the laws governing the merit system and civil service vary and often lack clarity, which may be difficult for public health agencies and for potential employees to understand, navigate, and successfully recruit key employees. The recruitment and hiring of new governmental public health staff are complicated by the management of hiring by other state agencies and the vague civil service exam requirements and process. Developing preferences for hiring individuals who have additional practical training in public health (eg, public health fellowships and AmeriCorps) should be considered.
