The Illinois Department of Human Services (IDHS) has been funding the Illinois Youth Survey (IYS) biennially since 1990, and CPRD has been responsible for the administration and management since 2013. The IYS is a student self-report survey administered in school settings, designed to gather information about a variety of health and social indicators, including substance use patterns and attitudes of Illinois youth. IYS results in a scientific statewide sample and four scientific sub-state sample estimates. CPRD ensures that schools and communities received their data back for planning and evaluation purposes.
