Parnassus Prep Sch–Grammar is a public charter school in Maple Grove serving kindergarten through fourth grade. It is part of the Parnassus Preparatory Charter School organization, a single-district charter network. As a charter school, it operates with its own board and admissions process rather than being part of the traditional Osseo Area Schools district that serves most of Maple Grove.
State testing results from the 2024–25 school year give a picture of academic performance in the tested grades. In math, a strong majority of students in both third and fourth grades met state standards. That is a clear strength for this early-elementary school. In English language arts, the share of students meeting standards was lower in both grades, with roughly two out of five students scoring proficient. A parent considering this school may want to ask the school directly about reading and writing support, especially since reading proficiency in the primary years is a foundation for later learning. Science results were suppressed for grade 5 because the tested group was very small, so no conclusion can be drawn there.
Only one year of testing data is available in this record, so there is no multi-year trend to assess whether performance is improving or declining. The overall proficiency rate across tested subjects and grades places this school in the top quartile relative to districts in Hennepin County, which is a positive signal when compared with the wider county.
The school serves a sizable elementary enrollment. The student body is diverse, with the largest racial group being Black students, followed by white students, Asian students, and smaller shares of Hispanic, multiracial, and other groups. More than half of the students qualify for free or reduced-price lunch, which is a measure of family economic need. Information on students with disabilities and English learners was not available in the data, so a parent should ask the school about those support services directly.
Maple Grove is a rapidly growing suburban city in the northwest Twin Cities metro area. It is car-dependent and built around single-family neighborhoods, retail complexes, medical campuses, and corporate office parks. Housing values are above the national median, and rents have been rising. The city has an emerging downtown corridor near the community center and library, but schools are located on separate campuses away from that center. This is not a walkable, urban school setting; families will likely need to drive for drop-off and pick-up. The school itself sits in a residential area.
No recent district-level changes were found in public records, so there is no notable controversy or major policy shift to report. The charter school status means it draws students from across the area, not just Maple Grove, though it is located there.
This school fits a family looking for a charter option with solid early math outcomes and a diverse student body. The lower reading scores suggest a need to investigate literacy instruction carefully. Because it serves only grades K–4, families will need to plan for a transition to a middle school, likely back to a traditional district or another charter. The absence of data on special education and English learner programs means those are open questions. For families who value a suburban charter with strong math in the primary grades and want to understand how reading is addressed, this school merits a closer look and a direct conversation with staff.
