Despite dismal student performance on annual exams covering math and reading, Illinois high school graduation rates remain high, according to a Prairie State Wire analysis of 2016 data from the Illinois State Board of Education.
The end-of-year tests known as the Partnership for Assessment of Readiness for College and Careers, or PARCC, are administered to third- through eighth-graders in Illinois, testing them based on Common Core standards. High-schoolers also took the tests through 2016.
A composite score combines the results of the subject tests. Students whose scores either met or exceeded expectations are considered "ready for the next level" by state standards.
Schools' graduation fraud index shows the difference between the composite passing rate and the graduation rate.
