What is required for each board member before they can perform their duties?

Each board member is required to have a certificate of appointment before they can perform their duties. This certificate is an official document that validates their role and responsibilities on the board, ensuring that they have been duly appointed by the appropriate authority. It serves as a formal acknowledgment of their position and is critical for legitimizing their participation in board activities.

While the other options may seem plausible for certain roles or responsibilities, the specific requirement of a certificate of appointment is what distinguishes the eligibility of board members in this context. A license from the state primarily pertains to individuals who are practicing psychology or providing psychological services, rather than its application to board members. Similarly, a background check, while a common prerequisite for many professional roles to ensure safety and credibility, is not universally mandated for all board members in this specific scenario. Lastly, a signed affidavit may be relevant in different contexts, particularly regarding declarations or oaths, but it does not fulfill the specific requirement for board members to officially commence their duties.
