Which of the following is NOT a requirement for maintaining a valid license?

Maintaining a valid license as a mechanical or gas journeyman typically includes certain requirements mandated by licensing authorities. Paying renewal fees is essential to ensure that the license remains active and is recognized by the licensing board. Continuing education credits are often required to keep professionals updated with current practices, safety standards, and regulations in the industry. Submitting a renewal application demonstrates the licensee's intention to maintain their credentials and provides the necessary documentation to the licensing authority.

Practicing on a regular basis, however, is not a formal requirement for maintaining a valid license. While regular practice may be beneficial for a professional's skill set and experience, the licensing authority focuses on administrative and educational requirements rather than the frequency of practice. Therefore, it is possible for someone to maintain their license without actively practicing, as long as they fulfill the other mandatory obligations.
