The commissioner may, subject to the requirements of subdivisions (b), (c), and (d) of Section 50318, suspend for a period not to exceed 12 months or bar a person from any position of employment with a licensee if the commissioner finds that the person has willfully used or claimed without authority a designation or certification of special education, practice, or skill that the person has not attained, or willfully held out to the public a confusingly similar
designation or certification for the purpose of misleading the public regarding his or her qualifications or experience.
