What occurs when a certificate holder files a timely renewal application?

When a certificate holder files a timely renewal application, the existing certification remains active until the renewal is reviewed and finalized. This process allows the certificate holder to continue their practice without interruption, ensuring that they can provide services while their application is being processed. This provision is important because it prevents any disruption in service and provides a safeguard for the certificate holder's clients, maintaining a consistent level of service.

In contrast, the other options do not accurately reflect the implications of a timely renewal. For instance, an immediate expiration of the certification would create unnecessary gaps in service and could negatively impact clients who rely on the certificate holder’s expertise. Requiring an immediate cessation of practice would further complicate matters, leading to potential legal ramifications and service interruptions. Lastly, while there may be fees associated with certifications and renewals, a timely application typically does not incur penalty fees, assuming all other requirements are met.
