Cusd 300

Cusd 300 includes 26 schools—18 elementary, four middle, three high schools and one alternative school—serving students from elementary through high school. In 2025–26, elementary and middle school results varied by 33 to 51 percentage points within comparable all-grades subjects, while high school ACT results also differed substantially by school. The most important takeaway is that district averages conceal sharply different school-level results.

Eastview Elementary stands out among elementary schools, with 74% proficient in ELA and 71% in math—18 and 31 points above state results. Lincoln Prairie and Kenneth E. Neubert also exceeded state results in both subjects. At the low end, Meadowdale had the lowest elementary ELA score, 26%, and Lakewood the lowest math score, 20%. Among middle schools, Algonquin Middle led ELA at 69%, while top math results were about 44% at Dundee Middle and Algonquin. Carpentersville Middle was lowest in both subjects, at 26% ELA and 11% math. At high schools, Jacobs led ACT ELA and science, while Hampshire led math; Dundee-Crown was lowest in all three subjects.

Results changed unevenly over time. Elementary average ELA rose about 1 point from 2024–25 to 2025–26, but the state result rose more, widening the schools’ average gap from 3 points below state to 5 below; elementary math average fell about 1 point. Middle-school averages gained ground: ELA rose from 47% to 53% and math from 29% to 32%, with gains at all four schools. SchoolDigger’s statewide rankings offer another perspective: Eastview is at the 84th percentile, and Lincoln Prairie and Neubert at the 79th; Golfview is at the 6th. Income measures provide context, not an explanation: in 2024–25, Dundee Middle and Hampshire Middle reported 37% and 34% free/reduced lunch eligible, while Dundee’s 2025–26 results were 66% ELA and 44% math, compared with Hampshire’s 53% and 30%.
