Summary:
Pontiac, Illinois, has five schools—three elementary schools, a junior high and a high school—serving students from early elementary through grade 12, with enrollment ranging from 221 to 658. The clearest overall pattern is that all three schools with reported all-grade IAR results scored below state levels: their average gaps were 17 percentage points in ELA and 18 points in math.
Pontiac Junior High School led the reported all-grade ELA results at 49%, compared with 36% at Washington Elementary School and 33% at Lincoln Elementary School; its score was 14 points above the other two schools’ average, but 7 points below the state. In math, Lincoln led at 31%—14 points above the other schools’ average—while Washington had the lowest result at 16%; Lincoln was still 9 points below the state. These are descriptive comparisons across schools serving different grades. At Pontiac High School, grade 11 ACT results were closer to state levels overall: ELA was about 1 point below the state, math 6 points below and science 4 points below.
Recent trends differ by school: Pontiac Junior High improved 9 points in ELA and 6 in math from 2024–25 to 2025–26, while Washington fell 5 points in ELA and 9 in math; Lincoln’s ELA was nearly unchanged and its math rose 1 point. Across the three schools, average gaps from the state widened by about 2 points in both subjects. Pontiac High’s ACT results also fell year over year—9 points in ELA and 8 in math—after being above state results in both subjects the prior year. SchoolDigger ranked Pontiac High at the 50th percentile, Pontiac Junior High at the 20th and Washington at the 10th in 2025–26. The reported free/reduced lunch eligible shares for 2024–25 ranged from 46% at Pontiac High to 67% at Central Elementary School; Washington’s student-teacher ratio was 10.2, compared with Lincoln’s 10.9, but those figures do not explain the score differences. Central has no supplied test scores, and the all-grade comparisons cover different grade groups.
