The purpose of this book is to help boards of directors of nonprofit organizations improve their performance after completing the Board Check-Up, online board performance self-assessment tool found at www.boardcheckup.com. This book is also valuable as a stand-alone resource for any board seeking to assess its performance in that it contains the diagnostic questions on which the online self-assessment tool is based. It goes further by providing a framework for boards to use in discussing needed changes in board performance. It also forms an integral part of a University at Albany, SUNY online course titled, The Governance of Nonprofit Organizations. This massive open online course (MOOC) can be taken for free or academic credit through Coursera’s online teaching and learning platform.
