Summary:
ZIP code 55330 is home to five schools labeled as middle schools — four serving grades 6–8 or 5–8 and one serving only grade 5 — with a combined enrollment of 2,586 students split between Elk River Public School District (three schools, 2,148 students) and the two-school Spectrum High School district (438 students). The Elk River district ranks 37 of 458 in Minnesota (92nd percentile, 5 stars), while the Spectrum district ranks 59 of 458 (87th percentile, 4 stars).
Prairie View Middle School is the largest and strongest overall performer, with 2025-26 math at 57.2% and reading at 59.8%, plus an 8th-grade math result of 74.8% that is far above both the state and district. Salk Middle School posted the biggest gains, raising reading by 7.0 points and science by 4.26 points while climbing from the 75th to the 85th percentile — notable given it has the highest free/reduced-lunch rate at 26.33%. Vandenberge Middle School improved reading by 7.76 points and rose to the 72nd percentile, but its 10.6% science score is the lowest in the area. Spectrum Middle School has strong reading (58.8%) and the lowest student-teacher ratio (16.7), yet its 8th-grade math of 27.9% is a clear weak spot. Spectrum Elementary School has the highest reading score in the set at 64.5%, but serves only grade 5, so its results are not directly comparable.
Reading is the area's consistent strength: all five schools exceeded the state's 48.6% mark. Science is the shared weakness, with no school surpassing its own district. Math is split, with Prairie View and Salk above the state average and the other three below. Student-teacher ratios range from 16.7 to 25.4, and the lowest-ratio Spectrum schools do not show the highest math and science results, so class size alone does not explain outcomes.
