The Illinois Youth Survey (IYS) is a self-report survey administered in school settings every year to 8th, 10th and 12th grade students, and gathers information about health and social indicators including substance use and perceptions, bullying, school climate, nutrition, and physical activity. This provides a scientific estimate of health and social indicators for the state of Illinois. It also supplies local data to schools and school districts at no cost, and provides critical information to school administrators, prevention professionals, and community members as they work to address issues in their communities. For more information, please visit: https://iys.cprd.illinois.edu/about
