Chicago magazine has ranked the Landmark coverage area’s two high schools as among the top public high schools in suburban Cook County. In its September issue, the magazine ranked Riverside-Brookfield High School ninth in suburban Cook County and ranked Lyons Township High School 13th.

The rankings were based on four equally weighted factors – spending per pupil, graduation rate, average composite score on the ACT college entrance exam, and the percentage of students who met or exceeded state standards on the Prairie State Achievement Exam. All data came from the 2010-11 school year.

According to Chicago magazine, RBHS spent $10,117 per student in the while LTHS spent $9,452 per student. RBHS had a 94.7 percent graduation rate while LTHS’s graduation rate of 89.8 percent was the lowest of the top 15 high schools in suburban Cook County.

RBHS’s average composite ACT score was 23.3 compared to 24.1 at LTHS, and 76 percent of RBHS students met or exceeded state standards on the PSAE compared to 73 percent at LTHS.

“We are very excited about the recognition we received in Chicago magazine,” said District 208 Superintendent Kevin Skinkis in an emailed statement. “The credit for all the hard work needs to go to the teachers and support staff who make RBHS a great place for students.”

Chicago magazine ranked Glenbrook North High School in Northbrook as the top public high school in suburban Cook County. New Trier High School in Winnetka was ranked second.
