A temporary permit shall entitle the applicant to engage in the fitting or sale of hearing aids for a period of one year under the direct supervision and training of a person holding a valid hearing instruments dispenser's license or a license as an audiologist under sections 20-395a to 20-395g, inclusive, or while enrolled in a course of study approved by the department, except that a person who holds a temporary permit shall be excluded from making selections of hearing aids.

(b) If a person who holds a temporary permit under this section has not successfully passed the licensing examination within one year from the date of its issuance, the temporary permit may be renewed once upon a payment of a sixty-dollar fee for such renewal.
