With the growth of athletic training, many state governing bodies have created regulations concerning the role of athletic trainers in their respective states. Some of these states have included the licensure, certification, and/or registration of athletic trainers as a prerequisite for employment. Although many states have similar requirements, each state differs in its legislation that affects various athletic training domains. Athletic trainers should be aware of these variances in state licensure laws, especially when seeking employment in another state. In May 1991, a survey of the 20 states with licensure laws was conducted to examine application procedures, scope of practice, and other factors related to the licensing of athletic trainers.
