The California Healthy Kids Survey (CHKS) is a powerful tool for use in K-12 schools that can help schools and districts accurately identify areas of student and school strengths and weaknesses, and address related needs. It provides a comprehensive, data-driven, decision-making process to guide efforts to improve school climate, learning supports, and engagement, as well as identify and increase the quality of health, prevention, and youth development programs. CHKS assesses a broad range of key learning and health-related indicators and collects student data on attitudes, behaviors, and experiences related to school and learning. School connectedness, developmental supports and opportunities, safety, violence and harassment, substance use, and physical and mental health are some of the key areas assessed by the survey. The research-based assessment of factors that promote resilience and positive youth development is one of the surveys many unique benefits. The CHKS allows schools and districts to receive relevant, useful knowledge that may be used in guiding service/program development.
