A license is valid for a 2–year term from issuance of the license as provided in this section. At least 1 month before a license expires, the Board shall mail or electronically transmit to the licensee: a renewal application form; and a notice that states: the date on which the current license expires; and the amount of the license fee. If an electronic transmission under paragraph (1) of this subsection is returned to the Board as undeliverable, the Board shall mail to the licensee, at the last known address of the licensee, the materials required under paragraph (1) of this subsection within 10 business days of the date the Board received the notice that the electronic transmission was undeliverable. Before a license expires, the licensee periodically may renew it for an additional 2–year term, if the licensee: otherwise is entitled to be licensed; pays to the Board the license fee set by the Board; and submits to the Board a renewal application on the form that the Board provides. The Board shall renew the license of each licensee who meets the requirements of this section. The Secretary may determine that licenses issued under this subtitle shall expire on a staggered basis. The Board shall adopt regulations to require a licensee to demonstrate continuing professional competency by completing at least 24 hours of professional development activities as a condition of renewal of a license under this section. The continuing professional competency requirement under paragraph (1) of this subsection does not apply to the first renewal of a license.
