Summary:
Monticello, Illinois, has three schools serving 1,437 students from prekindergarten through grade 12: Washington School (PK–3), Monticello Middle School (grades 6–8), and Monticello High School (grades 9–12). Overall, the reported 2025–2026 results are generally stronger than state benchmarks: 12 of 14 school-and-subject comparisons were above the state, one matched it, and one was just below. The clearest area-wide takeaway is that most reported results exceed their corresponding state figures, though strengths vary by school and subject.
Washington School stands out in math: 69% of students were proficient across reported grades, compared with 40% statewide, a 30-point advantage. Its ELA result was essentially at the state level. Monticello Middle School is strongest in ELA, with 78% proficient across grades versus 56% statewide, a 22-point lead; its math results were also above state figures in each grade. Monticello High School exceeded state results in every listed subject and grade, with its largest advantage in grade 11 ELA: 71% versus 50%, or 21 points.

At the high school, grade 11 ACT ELA rose 3 points, while math fell 4 and science fell 2; middle-school grade 8 science also lost its previous advantage over the state.
