In May 2022, the Office of the Governor of the State of Illinois commissioned a study on how students were making postsecondary education decisions. In collaboration with state agencies, IWERC designed and implemented a survey for high school seniors in Illinois that asked students about the factors that influenced their decisions to pursue higher education, including their views on in-state versus out-of-state colleges. In this series, we present findings through several reports on 4-year college goers, 2-year college goers, non-college goers, and the pandemic’s effects on college decision-making. We also include a technical reference guide which serves as the methodological document for all our reports.
