Illinois Youth Survey

The administration of the IYS has two major goals:

1. • To supply local data to schools and school districts throughout Illinois. During state-funded survey years (e.g., 2018, 2020, etc.), the survey is available to all eligible public and private schools in the state at no cost. Each participating school is eligible to receive a report specific to their own students’ responses. These local reports provide critical information to school administrators as they work to address substance use issues in their communities. 
   • To provide a scientific estimate of health and social indicators for the state of Illinois. The scientific estimate is based on a random sample representing the state population of 10th, and 12th graders in Illinois public schools.
