Summary

Montessori del Mundo Charter School is a small elementary charter school in Aurora, CO, serving 365 students in grades PK-6 and authorized by the State Charter School Institute, a district that ranks in the top half of Colorado schools. Despite this supportive oversight, the school's own performance ranks near the bottom of the state: in 2025-2026 it placed 902nd of 943 Colorado schools, earning 0 stars with just 16.2% proficiency in English Language Arts and 6.9% proficiency in math — far below state averages of 44.7% and 37.3%.

The school's most severe challenge is chronic absenteeism. In 2024-2025, 53.0% of students were chronically absent, the highest rate among nearby schools and far above the SCSI district average of 30.4%. The contrast with Aurora Quest K-8, just 1.38 miles away, is striking: Aurora Quest has only 4.7% chronic absenteeism and 92-96% proficiency in ELA and math. Math proficiency at Montessori del Mundo has remained persistently flat for four years, hovering between 5.6% and 6.9%, while ELA scores have swung widely — from 16.9% to 24.7% and back down to 16.2% — suggesting volatility rather than genuine momentum.

Poverty does not fully explain these outcomes. Although 67.1% of students qualify for free/reduced lunch, several nearby schools with higher poverty rates perform significantly better: Jewell Elementary (85.8% FRL, 30.8% ELA proficiency), Arkansas Elementary (75% FRL, 29.8% ELA), and Clara Brown Entrepreneurial Academy (74.1% FRL, 30.2% ELA) all achieve better results with higher-need populations. With a favorable 13.9 student-teacher ratio and more than half of students missing significant instructional time, attendance appears to be the single most actionable issue standing between this school and meaningful academic improvement.
