Acorn Montessori Charter School

The Acorn Montessori Charter School district has two schools serving kindergarten through grade 8: Acorn Montessori Charter School (grades 2–8) and Acorn Montessori Charter School Inc. - West (K–3), with 2025–26 ELA and math results available for both. Their strongest subjects differ: West leads in all-grades math, while the grades 2–8 school leads in ELA.

West stands out in math, with 47% proficient, compared with 32% at the other school and 33% statewide; its 14-point advantage over the state is the strongest all-grades result in the comparison. The grades 2–8 school stands out in ELA at 48%, 7 points above both West and the state. The weaker all-grades math result is at the grades 2–8 school, 1 point below the state. Its grade-level results vary sharply, however: grade 5 is a high point, with 53% proficient in math (15 points above the state) and 56% in ELA (18 points above). Grade 4 math is a low point, at 26%, 14 points below the state. Because the schools have different grade spans and no shared grade with reported results, these all-grades comparisons are not same-grade comparisons.

The grades 2–8 school’s SchoolDigger statewide percentile ranking rose from the 55th percentile in 2023–24 to the 66th in 2024–25, then fell to the 49th in 2025–26—a 17-point drop from the prior year in relative ranking, not a measure of test-score change. SchoolDigger rates the district at 2 stars and the 48th percentile. The school also exceeded state science results in its reported grades: 38% versus 34% in grade 5 and 36% versus 30% in grade 8. Enrollment is 294 at the grades 2–8 school and 266 at West; their student–teacher ratios are 22.6 and 24.1, respectively. Free/reduced-lunch rates are not available for either school.
