Final answer:
An individual providing services independently must have an occupational license, which is issued by a government agency and verifies their education or test completion. Such licensing is common across various professions, including healthcare, education, and law, to assure quality in the labor market.
Step-by-step explanation:
A practitioner who provides services outside of a licensed facility must hold an occupational license. Occupational licenses are critical in many professions to ensure that individuals meet specific standards of competency and practice safely and legally. These licenses are typically issued by government agencies and may require the completion of education programs, passing of exams, or both.
Professions that require such licenses include but are not limited to doctors, teachers, nurses, engineers, and lawyers. Certain jobs may require licenses in specific states—for example, a stress analyst in Louisiana or a bait retailer in North Dakota. Overall, occupational licensing serves as a mechanism to establish quality within the labor market, impacting around 29% of U.S. workers as per a 2013 University of Chicago study.
