What is the most restrictive form of state credentialing?

Licensure is recognized as the most restrictive form of state credentialing because it establishes a legal requirement for individuals to hold a specific license in order to practice a profession, such as athletic training. This form of credentialing is governed by state laws and typically involves meeting strict educational and examination criteria, as well as ongoing continuing education to maintain the license.

Obtaining a license often means that individuals must demonstrate a thorough understanding of the relevant laws, ethics, and skills necessary within their profession, which provides a level of authority and formal recognition that protects the public by ensuring that only qualified individuals are allowed to practice. This requirement differentiates licensure from other forms of credentialing, such as certification and registration, which do not typically involve the same level of oversight and regulatory control.
