Summary

Monticello Montessori Charter School is a small public charter school in Ammon, Idaho, serving 185 students in grades PK–8 and operating as its own charter district, Monticello Montessori Charter School Inc. The school's standout strength is attendance: only 5.8% of students were chronically absent in 2025–2026, the lowest rate among all 11 nearby schools and far better than the state average of 13.8%. This marks a dramatic turnaround from 36% just a few years ago, showing that students are consistently showing up to class.

Academically, the picture is more mixed. Monticello Montessori Charter School ranks 271st out of 346 Idaho elementary schools (22nd percentile, 1 star), the lowest of its local comparison group. State test scores show 30.2% proficiency in math and 34.8% in science, both well below state averages, while English language arts proficiency (51%) is close to the state's 54%. The contrast with Woodland Hills Elementary—located just 0.11 miles away on the same street—is striking: Woodland Hills ranks 55th with 61.6% math proficiency, while Monticello sits at the bottom of local rankings despite having much better attendance.

There are encouraging signs. ELA proficiency has climbed from 37.5% to 51% over two years, and 7th-grade math (45.5%) now exceeds the state average. However, math and science remain weak, and the school's small enrollment means a handful of students can swing proficiency percentages significantly from year to year. Families drawn to the Montessori approach and the school's impressive attendance record should weigh those benefits against standardized test results that continue to trail most area schools.

Test scores are low, they're losing students and administration is awful. Close Quote

This is a school that started out with great potential but has fallen away from the Montessori method. Frequent changes in staff, teachers, and administration has left the school dysfunctional. It barely passes as an ok school with a high teacher to student ratio. Close Quote
