Final answer:
To have a valid independent contractor's license, a person must also hold the required occupational license for their profession.
Step-by-step explanation:
Occupational licenses are used to establish quality in the labor market. They show that a worker has completed a certain type of education or passed a certain test. In order for an independent contractor's license to be valid, they must also hold the required occupational license for their profession. For example, if someone is an independent contractor in the field of plumbing, they would need to hold a valid plumber's license in addition to their contractor's license.
