The following story was provided by District 225.
According to the 2012 Illinois School Report Cards released by the Illinois State Board of Education (ISBE), Glenbrook North and Glenbrook South students perform consistently well above average on state tests. GBN students posted an average composite score of 25.9, while GBS students earned an average composite score of 24.3. The state average composite score is 20.6.
The 2012 Report Card lists the total enrollment of the Glenbrook High Schools as 4,748, which is 14 fewer students than the previous year. The district’s graduation rate of 95.6% is down 2.4%, resulting from a change in the required reporting implemented in 2010-11 under the Federal No Child Left Behind Act (NCLB). On average, 96-97% of Glenbrook graduates attend college.
NCLB sets annual targets for student achievement on the Illinois Prairie State Achievement Exams (PSAE). For 2012, 85% of all student subgroups are to meet or exceed standards on PSAE testing in order for the school to make Adequate Yearly Progress (AYP). The target level will rise by 7.5% each year, until the expectation level is 100% by 2014.
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 2012.
