Co-developed by the Children’s Funding Project and the Education Redesign Lab (EdRedesign) at the Harvard Graduate School of Education, this toolkit is designed to equip mayors and their staff with practical information and resources to launch a children’s cabinet in their local community. Mayors and their staff are the audience for this toolkit because of their ability to use the executive office’s bully pulpit and convening power to bring child- and youth-serving government departments and external agencies together. Through their leadership, mayors can signal a community’s priorities and foster a system of accountability within local child-serving systems. They also play an important role in cultivating relationships and securing resources. While this toolkit was created specifically for mayors and their staff, the content is relevant for a broad range of municipal leaders, including county executives, city managers, and others in similar roles.
