The scores for both schools would have been higher, but ACT recently changed the advertised school score by including scores for students who received ACT-approved testing accommodations.
“While test scores are not the only way we measure the success of our students, they do provide confirmation that the efforts we are making are having a positive impact on student achievement,” Superintendent Dr. Mike Riggle said in the press release.
The Report Card lists the total enrollment of the Glenbrook High Schools as 4,821. The district graduation rate is 97.8 percent. On average, 96 to 97 percent of Glenbrook graduates attend college.
The No Child Left Behind Act (NCLB) sets annual targets for student achievement on the Illinois Prairie State Achievement Exams (PSAE). For 2013, 92.5 percent of all student subgroups must meet or exceed standards on PSAE testing in order for the school to make Adequate Yearly Progress (AYP). The target level rises each year, and in 2014, 100 percent of students are expected to meet or exceed standards.
NCLB specifically measures the progress of nine subgroups of students including the following: Racial/Ethnic Background, Limited English Proficient, Students with Disabilities and Economically Disadvantaged.
Based on the performance of some subgroups, GBN, GBS, and the district did not meet AYP for 2013.
The official State Report Cards will be posted on the district website (www.glenbrook225.org) by Oct. 31, 2013.
