N.J. Stat. Ann. § 45:9-37.48

14. Each initial application under P.L.1984, c.203 (C.45:9-37.35 et seq.) shall be accompanied by a fee as prescribed by the board. Licensure shall expire biennially on January 31 and shall be renewed upon application and payment of a fee as prescribed by the board. If the fee is not paid by that date the license shall automatically expire. A license which has expired may, within three years of its expiration date, be renewed on payment to the board of the prescribed reinstatement fee for each year or part thereof during which the license was ineffective and a restoration fee as prescribed by the board. After the three-year period, the license may be renewed only by complying with the provisions of P.L.1984, c.203 (C.45:9-37.35 et seq.) regarding initial licensure and presenting proof of current certification by the Board of Certification for the Athletic Trainer or its successor organization.
