Definition
A board member holding a specific leadership role — typically president, vice president, treasurer, or secretary.
Officers are the board members who hold defined leadership roles, usually president, vice president, treasurer, and secretary. They're generally elected by the board from among the directors after the membership elects the board.
Officers carry specific duties set by the bylaws, but they act on behalf of the board, not independently. Clear role definition among officers is a foundation of a smooth-running board.
