N.J. Stat. § 45:3-44
Certificates for certified interior designers shall expire on a date to be determined by the Director of the Division of Consumer Affairs in the second year following the year of issuance, renewal or reinstatement, and shall become invalid on that day unless renewed. On a date to be determined by the Director of the Division of Consumer Affairs in the year of expiration of a certificate, the secretary of the board shall notify all persons certified under this act of the date of the expiration of their certificates and the amount of the renewal fee. Notice shall be mailed to each holder of a certificate at the holder's last post office address known to the board.
Certified interior designers shall apply for renewal on a date to be determined by the Director of the Division of Consumer Affairs in the year of expiration of a certificate. A certificate shall not be renewed until the certificate holder submits satisfactory evidence to the committee that during the preceding two years the certificate holder has completed such continuing education credits as are to be determined by the committee. The committee shall approve continuing education that builds upon basic knowledge of interior design services in accordance with the guidelines established by the Interior Design Continuing Education Council (IDCEC), and which updates the competency of the certificate holder. The committee may make exceptions from the continuing education requirement in emergency or hardship cases with the approval of an affirmative vote of a majority of the board.
Failure on the part of the holder of a certificate to renew the certificate every two years shall not deprive that person of the right of renewal during the ensuing two years, but a reinstatement fee shall be added to the certification fee; and if the certificate is not renewed within the two years following its expiration, the holder of the certificate shall pay a reinstatement fee for each two years or portion thereof in which the holder is in arrears. Continuing to use the title "certified interior designer" after the expiration of the certificate shall be a violation of this act.
A duplicate certificate to replace one lost, destroyed or mutilated may be issued subject to the rules and regulations of the board, and a reasonable fee, to be established by the board, may be charged for each duplicate certificate. An unsuspended, unrevoked and unexpired certificate as a certified interior designer under this act shall be prima facie evidence in all courts and places that the person named therein is certified. Each certificate shall be recorded by the board in the office of the Secretary of State, in a book kept for that purpose, and any recording fee as may be provided by law shall be paid by the applicant before the certificate is delivered.
