Each community has a complex makeup of intricate systems, cultures, and resources. Developing relevant and lasting systems for safe and supportive school environments requires communities, and the people and institutions within them, to be at the center. Tackling complex problems requires change within and across institutions and local systems and among the individuals working and living within them. Schools exist within communities. When a community is engaged in schooling, the entire school (including students and teachers) has expanded access to the resources offered by the community. The community also has an opportunity to deepen its investment in the outcomes of its youth. Part of Center for Education Equity's (CEE's) "Exploring Equity Issues" series, this paper defines community engagement and offers strategies on ways schools and communities can work together to support student achievement.
