Final answer:
The renewal of a professional certificate typically has a grace period after expiration, but if expired for a significant amount like 365 days or more, renewal might not be possible and re-certification could be necessary.
Step-by-step explanation:
The question relates to the protocols around the renewal of professional certifications, which can vary depending on the specific industry, country, or certifying agency. Generally speaking, there is a grace period after a certificate expires during which it can be renewed, but if a certificate has been expired for a significant amount of time, such as 365 days or more, the individual may not be able to renew it and might have to undergo the certification process again from the beginning. It's important to check the specific rules and regulations of the certifying body to understand the exact timeframe that applies.
