The Panel on the Nonprofit Sector released Principles for Good Governance and Ethical Practice: Guide for Charities and Foundations in October 2007, based on comprehensive analysis of over 50 systems of self-regulation and best practices, two public comment periods, and the involvement of charities and foundations nationwide. The guide's 33 practices are designed to support board members and staff leaders of every charitable organization as they work to improve their own operations. The Reference Edition includes legal background for each Principle, studies on self-regulation systems, and a glossary of terms. An Executive Summary is available for those who want a brief overview of the Principles. The Panel encourages charity and foundation leaders to examine the Principles carefully and determine how best they should be applied to their own operations.
