Clifford Johnson, which enrolls 63% economically disadvantaged students, scored below district proficiency averages but still cleared that bar. Wiesbrook rated "somewhat above expectations" in math performance and "somewhat below expectations" in reading performance. Whittier rated "well above" in math performance and "somewhat above" in reading.
Across the district, CUSD 200 elementary students tested at 56% math proficiency and 62% reading proficiency, according to the district's U.S. News page. Both figures topped the Illinois statewide averages of 37% in math and 43% in reading.
CUSD 200 has 13 ranked elementary schools across its 20-school district. Rankings for the remaining six were not included in this review.
The rankings weigh four factors equally at 25% each: math proficiency, math performance, reading proficiency and reading performance. Half the formula measures raw scores, and the other half puts those results in the context of student demographics, according to U.S. News. The data draws on 2023-2024 state assessments.
Steve Barnett, director of the National Institute for Early Education Research at Rutgers University, said in the U.S. News report that parents often lack good tools for evaluating schools. "What information could they use? Often, they don't have anything but reputation, which doesn't tell you about what the school contributes," Barnett said.
The full rankings cover nearly 47,000 elementary schools and more than 24,000 middle schools nationwide.
