Under what condition can the Board reinstate the certificate of a professional counselor who has failed to renew?

The correct option outlines that the reinstatement of a professional counselor's certificate is at the discretion of the Board. This means that the Board has the authority to evaluate each individual case and decide whether to reinstate the certificate based on various factors they consider pertinent. While the counselor may have the opportunity to apply for reinstatement, the ultimate decision lies with the Board, allowing them to weigh the specific circumstances surrounding the failure to renew.

In contrast, the other options imply conditions that do not fully encapsulate the Board's role in the process. For instance, simply applying for reinstatement does not guarantee that the Board will approve it; they must decide whether reinstatement is appropriate. A hearing may be conducted for various reasons, but it is not a strict requirement for every case and relies on the Board's discretion. Finally, the request from a client does not have the authority to compel the Board to reinstate a counselor’s certificate, as the Board maintains regulatory authority over such matters.
