If the board finds that the applicant has submitted the credentials required by this act for admission to the examination, and has paid the license fee required by this act, the board shall admit such applicant to the examination and the department shall issue a license to practice as a cosmetologist or teacher as the case may be to those successfully passing the required examinations: Provided, That if the applicant fails to pass the examination he or she may be eligible to take the next examination. Examinations shall be held at least four times a year in the metropolitan areas of Philadelphia, Pittsburgh, Wilkes-Barre, Harrisburg, and Erie at such hours as it shall prescribe pursuant to section 812.1 of the act of April 9, 1929 (P.L. 177, No. 175), known as "The Administrative Code of 1929."
