Summary

Acorn Montessori Charter School is a 294-student school in Prescott Valley, Arizona, serving grades 2–8. Its clearest broad academic advantage is English language arts (ELA): 48% of students were proficient in 2025–26, compared with 41% statewide and 47% in the district. The school’s ELA result was also higher than those of the nearby schools overall. The clearest takeaway is that ELA is Acorn’s most consistent academic strength.

Math is more mixed: the all-grades result was 32%, close to the state’s 33% but below the district’s 35%. That figure compares favorably with the nearby schools’ average of 20%, but hides weaker results in 4th grade (26%, versus 40% statewide) and 7th grade (22%, versus 27% statewide). In 8th-grade math, Acorn led the nearby schools with 32%; in 7th grade, it had the lowest result among the five schools reporting scores. ELA was especially strong in 5th grade, at 56% versus 38% statewide, and Acorn also led the nearby schools reporting 6th- and 8th-grade ELA results. Science was above the state in both tested grades in 2024–25: 38% versus 34% in 5th grade, and 36% versus 30% in 8th grade.

Acorn’s SchoolDigger statewide ranking was at the 49th percentile with 2 stars in 2025–26, second among the five nearby schools, but down from the 66th percentile the year before. Science trends vary: 8th-grade proficiency rose from 23% in 2022–23 to 36% in 2024–25, while 5th grade fell from 47% to 38% over those years despite a recent rebound. Acorn has the smallest enrollment among nearby schools, but its 2024–25 student-teacher ratio was the highest, at 22.6 students per teacher versus a nearby average of 18.2. Its free/reduced-lunch rate was 56% in 2022–23. SchoolDigger’s relative ranking for White students was at the 27th percentile in 2025–26, 22 points below Acorn’s overall percentile; its Female Students ranking rose from the 22nd percentile in 2021–22 to the 65th in 2024–25, close to the school’s overall 66th-percentile standing that year.
