Over the past decade, surveillance systems and surveys have emerged to monitor student health behaviors, aiding public health approaches in preventing risk behaviors and promoting health. These systems are vital for understanding problems, tracking trends, and shaping interventions. Military-related events negatively impact academic and emotional outcomes for military-connected (MC) children. The Building Capacity in Military-Connected Schools initiative, a collaboration between USC and eight districts, aims to foster inclusive and supportive school environments for both military and nonmilitary students. The California Healthy Kids Survey (CHKS), a comprehensive surveillance system, mandated by the state’s Department of Education, collects data from students, parents, and school staff. The Building Capacity initiative expanded this by including modules specifically addressing military connections. Surveys revealed priorities like bullying, mental health, and threat assessment. Districts used this data to organize workshops, implement new programs, and consider policies for supporting MC students, creating safer and more tailored school environments. These surveillance systems empower districts to develop targeted, evidence-based interventions and policies based on unique school needs and shared concerns.
