A conflict of interest policy is standard for most nonprofits, but a code of conduct and ethics lets you go beyond just financial conflicts and look at all aspects of being a board member. This could also be called a board agreement. It lays out basic guidelines for group norms, before you need them. Just like any group where you bring together a group of people who don’t know each other, they need to specify how they are going to work together.
