California Business And Professions Code Section 2746.8

Each certificate issued pursuant to this article shall be renewable biennially, and each person holding a certificate under this article shall apply for a renewal of his certificate and pay the biennial renewal fee required by Section 2815.5 every two years on or before the last day of the month following the month in which his birthday occurs, beginning with the second birthday following the date on which the certificate was issued, whereupon the board shall renew the certificate. Each such certificate not renewed in accordance with this section shall expire but may within a period of eight years thereafter be reinstated upon payment of the biennial renewal fee and penalty fee required by Section 2815.5 and upon submission of such proof of the applicant`s qualifications as may be required by the board, except that during such eight-year period no examination shall be required as a condition for the reinstatement of any such expired certificate which has lapsed solely by reason of nonpayment of the renewal fee. After the expiration of such eight-year period the board may require as a condition of reinstatement that the applicant pass such examination as it deems necessary to determine his present fitness to resume the practice of nurse-midwifery.
