What does the term 'expired' specifically refer to in a certification context?

In a certification context, the term 'expired' specifically refers to a ceased validity of a certification. When a certification is described as expired, it means that the granted certification has reached the end of its designated validity period and is no longer recognized as valid unless it has been renewed or re-certified. This can occur due to not meeting ongoing education requirements or simply because the term of the certification has lapsed. In essence, an expired certification implies that the individual is not currently in compliance with the standards or criteria set forth by the certifying body, and thus, cannot claim the benefits associated with being certified.
