Summary:
Parnassus Preparatory School is a three-school district in Maple Grove, Minnesota, serving kindergarten through 12th grade across an elementary, a middle school, and a high school, with 1,352 students enrolled. The district ranks 119th of 458 in Minnesota — the 74th percentile, 4 stars — but its three schools perform very differently.
Parnassus Prep School-Rhetoric is the standout: it ranks 11th of 473 high schools statewide (98th percentile, 5 stars), has earned 5 stars each of the last three years, graduates 97.6% of students versus the state's 84.9%, and posts proficiency of 59.6% in math, 66.7% in reading, and 58.8% in science — all far above state averages — with the smallest classes at 13.6 students per teacher. Parnassus Prep School-Grammar sits near the state middle (50th percentile, 2 stars) with a split profile: math proficiency of 62.3% is well above the state's 44.9%, while reading of 38.5% falls below the state's 48.6%. Parnassus Preparatory School-Logic has slipped from the 73rd to the 55th percentile over three years and trails the state in math (36.1%), reading (46.6%), and science (17.6%), with the largest classes at 21.1 students per teacher.
Grade-level results show where each school shines or struggles. Grammar's third-grade math is 68.9% against the state's 57.9%, but its fourth-grade reading is 34.4% against the state's 48.8%. Logic's eighth-grade reading (54.9%) beats the state's 50%, while sixth-grade math (30.1%) lags the state's 39.5%. Rhetoric's 11th-grade math (59.6% vs. 35.3%), 10th-grade reading (66.7% vs. 42.5%), and science (58.8% vs. 35%) are exceptional. In short: one elite high school, a median elementary with strong math and weaker reading, and a middle school losing ground in math and science.
