State test scores for students at Chicago charters and district-run schools are virtually the same, and in some cases Chicago Public Schools (CPS) are doing better, according to new data analysis. Elementary students who attend schools run by the CPS district are largely outperforming their counterparts at charters and other privately-run schools in the city when it comes to math and reading scores on state exams.
According to an analysis of 2013 state test scores by the Chicago Sun-Times and the Medill Data Project at Northwestern University, 9.8 percent of elementary students at traditional Chicago public schools scored above the reading standards on the Illinois Standards Achievement Test (ISAT) in 2013, compared with 7.9 of students at privately-run schools.
On the math section of the ISAT, just 5.3 percent of elementary students at privately-run schools surpassed standards in 2013, compared with 7.3 percent of students at district-run schools.
However, 1.3 percent of high school students at privately-run schools exceeded standards on the math section of the Prairie State Achievement Examination in 2013. By comparison, just 0.7 percent of high school students at CPS-run schools surpassed the math standards. On the PSAE's reading section, 1.6 percent of students at both traditional public high schools and privately-run high schools scored above the standards.
Meanwhile, high school students at charter schools scored on average 0.4 percentage points better on the ACT than students at other Chicago public schools, CPS spokesman Joel Hood told the newspaper. Hood also contends that CPS-run high schools have worse graduation and attendance rates than similar charter high schools.
