What typically signifies the end of an individual's certification?

The conclusion of an individual's certification is usually indicated by the expiration date being reached. Certifications often have a set validity period, after which they are no longer recognized unless renewed. This expiration is designed to ensure that certified individuals remain up-to-date with current practices, laws, and technologies relevant to their field.

While final assessments and the accumulation of required credits are important aspects of initial certification or recertification processes, they do not by themselves signify the end of a certification. Formal resignation from the field also does not automatically end a certification, as individuals may remain certified even if they choose not to actively practice in the field for a period of time. Thus, the expiration date is the definitive marker that indicates when a certification is no longer valid unless appropriate steps are taken for renewal.
