Original Research by School Decision on Aspen Ridge Preparatory School
Aspen Ridge Preparatory School is a charter school serving kindergarten through eighth grade in Erie, Colorado, as part of the St. Vrain Valley School District. The school operates with a kindergarten-through-eighth-grade structure, meaning there is no high school on site, and parents should plan for a transition after eighth grade.
The student body is predominantly white, with Hispanic and Asian students together representing a modest share of enrollment. A very small proportion of students qualify for free or reduced-price lunch, which places the school in a relatively affluent demographic context. Enrollment is large for a kindergarten-through-eighth-grade school, with more than 500 students spread across nine grades; class sizes appear to vary by grade level, with some grades having noticeably more students than others.
On state assessments administered in the 2024-25 school year, Aspen Ridge’s overall proficiency across tested subjects and grades placed it in the top quartile relative to other districts in Weld County. The school’s math proficiency among third through eighth graders was a strength, landing above the midpoint of the county comparison set. English language arts proficiency for that same grade span was a bit lower. In science, fifth graders showed a proficiency level that was lower than the school’s eighth grade science proficiency, which was the strongest subject result across the school. A parent looking at these results may want to ask about how the school supports students whose skills in reading and writing lag behind their math performance.
The school is a charter school within the St. Vrain Valley School District. A parent considering Aspen Ridge should understand that charter schools operate with some autonomy from the district in exchange for accountability on performance goals. The district itself recently approved a large capital projects bond to fund school construction and renovations across its 60 schools and programs, which could have long-term impacts on facilities and capacity.
Erie is a fast-growing community straddling Weld and Boulder counties. The town has seen substantial population growth in recent decades, and its planning area is much larger than its current incorporated footprint, signaling continued development. The historic Old Town area along Briggs Street provides a downtown core with dining and the Art Center of Erie, but much of the town is car-dependent suburban development. Housing values and rents in the area are high relative to national benchmarks, and the market has shown signs of cooling slightly. The town’s family-oriented character is evident in the share of households with children. The community is served by multiple school districts depending on location, and Aspen Ridge sits within the St. Vrain Valley district’s Erie attendance zone.
For a family considering this school, the academic picture is one of solid performance with a particular strength in math relative to peer districts in Weld County, and the school’s charter status may offer a distinct approach or culture that is worth exploring directly with the school. The high affluence of the student body may be a fit for some families, but others should consider that peer demographics can shape the school environment in many ways. A parent should also factor in that the school ends at eighth grade, requiring a separate high school search. The broader context of Erie’s rapid growth means that the town and its schools are likely to see continued change in the years ahead.
