The right of the government to control the practice of any profession or vocation derives from police power the sovereign holds for protection of the public "health, safety, and welfare." Practitioners of certain professions or vocations may be required to become "licensed" (also called registered, and sometimes certified) if their actions and judgments affect the public. Laws requiring licensing are framed and administered with protection of the public as the intent. Setting high or arbitrary standards for the purpose of limiting the number of practitioners would be a violation of that intent. Thus, applicants for licensing are only required to meet "minimum standards" as set by law and the codes and rules used to administer the law.
