      (a)   

         1.    Each section of the examining board shall promulgate rules to do all of the following:

            a.    Allow the holder of a credential under this chapter who is at least 65 years of age or has actively maintained that credential for at least 20 years, which need not be consecutive, and who certifies that he or she has retired from and no longer engages in the practice for which he or she holds the credential to apply to the board to classify that credential as retired status.

            b.    Allow an individual who previously held a credential under this chapter, and failed to renew that credential prior to the renewal date, to apply to the board to renew the credential with retired status if the individual is at least 65 years of age or had actively maintained that credential for at least 20 years, which need not be consecutive, certifies that he or she has retired from and no longer engages in the practice for which he or she previously held the credential, and pays the fee under par.

      (d)    The renewal fee for a credential holder whose credential is classified as retired status under par. (a) shall be one-half of the usual renewal fee that otherwise applies.
