Here’s a selection of items to include in the board manual for new board members. Many of these documents you already have. If you find you need to create documents, your current board members will appreciate having them as well, so be sure to share them with everyone. Keep everything brief, but informative.
Consider whether it makes more sense to have these as printed documents, or if you would rather create a shared online area to store them. Every board and board member is different in how they prefer to receive information. Google Drive is a low-cost solution that nonprofits often use for sharing documents.
