This joint study by the University of Chicago Consortium on School Research and the To&Through Project points to important differences between the four-year and six-year completion rates for Chicago Public Schools (CPS) graduates who received bachelor's degrees. It investigates four-year and six-year college completion trends for 2004-14 CPS graduates, as well as patterns of bachelor's degree completion for students who attended different colleges and different high schools, students with different GPAs and ACT scores, and students with different races/ethnicities and genders. As college application deadlines approach for students across Chicago and across the country, the four-year and six-year college completion rates could guide students' and families' decisions on where to apply and enroll.
