A conflict of interest usually means you or a close family member could benefit financially from PCSI decisions.
Common examples: a family member works for PCSI, you or a family member owns or works for a business that sells goods or services to PCSI, or serves on the board or staff of an organization that receives funding from PCSI or competes with PCSI for the same grants.
Having participated in PCSI programs is not a conflict of interest. A conflict doesn't automatically disqualify you; the board just needs to know about it so it can be managed.
