Original Research by School Decision on Montessori Del Mundo Charter School
Montessori del Mundo Charter School sits in Aurora, a sprawling suburban city that ranks as Colorado’s third-largest and stretches across three counties. The school operates under the State Charter School Institute, a statewide authorizer that oversees charter schools directly rather than through a local district. For families, that means the school has its own board and its own budget, separate from Aurora Public Schools or Cherry Creek Schools, the two large districts that serve most of the city.
The school serves prekindergarten through sixth grade, so there is no high school here and no graduation rate to report. Enrollment is roughly what you would expect for a charter school serving these grades in this setting. The student body is predominantly Hispanic, with a much smaller share of white students and very small numbers of Black, Asian, and multiracial students. A substantial share of students qualify for free or reduced-price lunch, which places the school in a higher-poverty context. The school is a regular public charter school, not a magnet, special education, or alternative program.
State testing results are available for math, English language arts, and science for grades three through eight. The strongest area is English language arts, where roughly a quarter of students scored proficient or above. Science results from fifth grade were suppressed for privacy, so a precise picture is not available there. Math proficiency is low; a very small share of students met the state standard. Overall, when looking across all tested subjects, the school’s combined proficiency index sits in the bottom quarter among Arapahoe County districts that have tested populations. This is a straightforward fact about performance, not a judgment, but it is a data point that parents considering the school may want to discuss with the staff to understand what supports are in place and how the school measures progress over time.
Because this is a charter school, Montessori del Mundo follows the Montessori method. The school’s name makes that explicit. For families who value that pedagogical approach—multi-age classrooms, student-directed work, extended cycles of learning—that is the central programmatic identity. The school does not appear to offer specialized career or technical pathways, advanced placement courses, or dual-credit programs; those are typical of high schools, and this school stops at sixth grade.
The housing market in the school’s zip code shows home values slightly below the state median and rental prices that have softened modestly over the past year. Aurora itself has grown steadily for decades, with major employers including Buckley Space Force Base, the Anschutz Medical Campus, and the city government. The school is located in a part of Aurora that is largely car-dependent suburban development, served by RTD light rail and bus routes but not a walkable grid. For families, the commute to the school is likely to be by car, and the broader community offers the amenities of a large suburban city rather than a small town.
The district brief turned up no recent lasting changes at the State Charter School Institute level that would affect day-to-day schooling, such as property-tax measures or curriculum shifts. That is typical for a statewide authorizer with many schools; most operational decisions happen at the school building level.
In sum, Montessori del Mundo is a small, prekindergarten-through-sixth-grade charter school in a large suburban city, serving a high-poverty, predominantly Hispanic student body with the Montessori method as its programmatic anchor. State math scores are low, English language arts scores are higher but still below the midrange of the county, and there is no high school component. Families whose priority is Montessori education and who are prepared to engage with the school around academic support for math may find this a fit. Families looking for a typical elementary school with a strong testing profile or a feeder into a high-performing high school should note that the school ends at sixth grade and the academic data here warrants a close conversation with the school itself.
