The Funders Collaborative for Youth Organizing engaged Community Science to develop a written guide for youth-organizing groups that would enable them to strengthen their organizations. The guide was not intended to replace the use of skilled consultants and other resources, but to better prepare these organizations in determining what they needed to do before seeking additional help and to start them on the process of organizational development. The guide was written by Community Science in collaboration with national experts and staff of youth-organizing groups. Community Science investigated past works with similar goals, assessed needs and past successes of 34 youth-organizing groups, and field-tested products with potential users.
