Final answer:
Personal-care professionals must be educated and licensed, with occupational licenses validating their qualifications. Licensing is mandated across various professions and is a requirement for about 29% of U.S. workers. Specific licenses can be unique to certain states for particular job roles.
Step-by-step explanation:
Personal-care professionals must be educated and licensed in each state to ensure quality service and consumer protection. Occupational licenses, which are required for jobs as varied as doctors, engineers, massage therapists, and real estate brokers, serve as an important signal of a professional’s competency. These licenses demonstrate that an individual has acquired the necessary education and has passed relevant examinations to perform their services.
Resumes, recommendations, school transcripts, and work examples are among the tools used by labor sellers to establish their qualifications and capabilities in the labor market. However, for approximately 29% of U.S. workers, an occupational license is also a critical requirement to legally perform their jobs, according to the University of Chicago study. Certain professions only require licenses in specific states, such as field archeologists in Minnesota or bait retailers in North Dakota.
