Grounded in the context of the gap in civic participation, action-based civics curricula, and how classroom interactions may affect student development, we present the CIVVICS (Civic Interactions motiVating diVerse Individuals in Classroom Settings) observation tool. CIVVICS's four domains--Lesson Planning and Implementation, Classroom Interactions, Student Engagement, and Civic Empowerment--integrate awareness of classroom organization and student engagement with attention to how a classroom promotes students' connections to civic goals and engages all students in positive interactions. This tool can be used to inform curricular implementation as well as professional development for interventions that promote democratic classroom climates and youth empowerment. We demonstrate the use of CIVVICS in partnership with Generation Citizen, a youth civic education program.
