There is no local top or bottom school to compare because Pontiac is the only school in the list. Compared with Illinois, its strongest subject in 2025–2026 was science, where results averaged 2 points below the state; ELA averaged 3 points below, and math 6 points below. Pontiac was behind the state in math at all three tested levels: 34% versus 40% on the 11th-grade ACT, 33% versus 36% on the 10th-grade PreACT, and 33% versus 42% on the 9th-grade PreACT. These subject comparisons offer a clearer picture of relative strengths and needs than a within-area school ranking can.
