What is the designation for a written authorization allowing a practitioner to operate outside their licensed facility?

The correct designation for a written authorization allowing a practitioner to operate outside their licensed facility is a temporary permit. This type of permit is typically issued by regulatory agencies or licensing boards to allow professionals to provide services in situations that fall outside of their usual practice location or for a limited duration. This is essential for ensuring that practitioners can legally offer their services in various settings, such as during events or in remote areas, while still adhering to safety and legal standards.

The other options like freelance license, affiliate license, and field license do not accurately describe the mechanism used for granting temporary operating authority outside the usual licensed facility. A freelance license might imply a broader working arrangement without specific temporary conditions, while an affiliate license suggests a formal relationship with another entity rather than a temporary authority for practice. Field license might imply a regulation specific to certain professions but does not represent a standard term used in this context. Thus, the term 'temporary permit' accurately reflects the formal and legal structure that supports practitioners in providing their services outside of their usual environments.
