Summary:
The four schools in Monticello CUSD 25 serve students from prekindergarten through grade 12, with 1,707 students total and enrollments ranging from 270 to 543. Their clearest shared strength is at the high school: its 2025–2026 results were above state results on all nine supplied ACT and PreACT measures. The most important qualification is that strong test and graduation results coexist with the district’s highest chronic absenteeism.
The IAR results show different school leaders by subject. Monticello Middle School led ELA with 78% proficient, followed by White Heath Elementary School at 72%; Washington School was lowest at 56.2%, just 0.1 point below the state’s 56.3%. In math, Washington led at 69.3%, 23 points above Middle’s 46%; White Heath was between them at 49.4%. All three were above the state’s 39.6% math result. At the high school, ACT ELA was 71% proficient, 21 points above the state, and graduation was 96%, 7 points above the state. However, chronic absenteeism there was 25%, compared with 8% at Washington, 13% at Middle, and 9% at White Heath.
Across the three IAR schools, average results rose from 64% to 68% in ELA and from 51% to 55% in math between 2024–2025 and 2025–2026. White Heath improved in both subjects (ELA up 9 points; math up 4), while Washington’s ELA fell 2 points even as its math rose 2. SchoolDigger gives the district four stars and ranks it 186 of 738; it also gives four stars to the high school, Middle, and White Heath, whose rankings are in the 83rd, 71st, and 72nd percentiles. Student–teacher ratios range from 13.5 to 15.5. For 2024–2025, free/reduced lunch eligible figures were 26% at Washington and 23% at both Middle and White Heath; the high school’s 26% figure is from 2021–2022, so it is not directly comparable.
