Bus. & Prof. Code, § 101.6

The boards, bureaus, and commissions in the department are established for the purpose of ensuring that those private businesses and professions deemed to engage in activities which have potential impact upon the public health, safety, and welfare are adequately regulated in order to protect the people of California.

To this end, they establish minimum qualifications and levels of competency and license persons desiring to engage in the occupations they regulate upon determining that such persons possess the requisite skills and qualifications necessary to provide safe and effective services to the public, or register or otherwise certify persons in order to identify practitioners and ensure performance according to set and accepted professional standards. They provide a means for redress of grievances by investigating allegations of unprofessional conduct, incompetence, fraudulent action, or unlawful activity brought to their attention by members of the public and institute disciplinary action against persons licensed or registered under the provisions of this code when such action is warranted. In addition, they conduct periodic checks of licensees, registrants, or otherwise certified persons in order to ensure compliance with the relevant sections of this code.
