Summary:
Parnassus Prep School-Rhetoric is the single high school serving grades 9–12 in the Parnassus Preparatory School district in Maple Grove, Minnesota, enrolling 258 students.
This school is a standout by nearly every measure in the data. It has earned a 5-star rating and a top-5% statewide placement for three straight years: 11th of 473 high schools (98th percentile) in 2025–2026, 23rd of 450 (95th percentile) in 2024–2025, and 18th of 480 (96th percentile) in 2023–2024. For context, the district as a whole is ranked 119 of 458 with 4 stars and a 74th percentile placement. Outcomes for the 2024–2025 school year are equally strong: a 97.6% graduation rate compared with Minnesota's 84.9%, and a 2.3% dropout rate compared with the state's 4.2%. These figures reflect a meaningful level of economic need in the student body, with 36.82% of students eligible for free or reduced lunch, and a student-teacher ratio of 13.6.
Test proficiency in 2025–2026 sits well above state averages in every subject tested. Science is the strongest relative signal at 58.8% versus the state's 25.5% — more than double — and it also rose sharply from 42.86% the prior year. Math climbed from 50.94% to 59.6% against a state rate of 44.9%, while reading was 66.7% versus the state's 48.6%, a small dip from 69.35% that still leaves it far above average (note the reading exam label changed between years, so that comparison is not perfectly like-for-like). Grade-level results are especially striking: 11th-grade math at 59.6% versus 35.3% statewide, 10th-grade reading at 66.7% versus 42.5%, and end-of-course science at 58.8% versus 35.0%. With only 258 students, percentages can shift on small cohort changes, but the three-year ranking record shows this is sustained performance rather than a one-year spike.
