What is required to renew an unexpired registration?

To renew an unexpired registration, the primary requirement is paying the renewal fee before the expiration date. This process ensures that the individual's registration remains active and compliant with the regulations set by the Texas Department of Public Safety's Private Security Bureau. Timely payment of the renewal fee demonstrates the individual's ongoing commitment to maintaining their registration without any lapses, which is crucial for continued practice in the field of private security.

The other options, while related to training and compliance, do not pertain directly to the specific requirement for renewing an unexpired registration. Completing additional training programs may be necessary for other updates or changes in regulations, but it is not mandated for all renewals. Taking reexaminations can occur under certain circumstances, but it is not a standard requirement for every renewal. Filing an appeal with the board typically pertains to disputes or denials of applications rather than straightforward renewal processes. Therefore, the correct focus for renewing an unexpired registration is simply the renewal fee.
