Summary:
The Elk River Public School District in Minnesota contains six high schools serving about 4,351 students, and the district overall ranks 37 of 458 districts (92nd percentile, 5 stars) with an 89.0% graduation rate and a 3.7% dropout rate, both better than the state's 84.9% and 4.2%. Three comprehensive high schools — Rogers Senior High (1,888 students), Elk River Senior High (1,562), and Zimmerman High School (704) — enroll about 95.5% of those students. The other three are much smaller: Ivan Sand Community High School (88), Online728 High School (81), and C.O.M.P.A.S.S. (28, grade 12 only).
Among the comprehensive schools, Rogers Senior High is the academic leader, with the highest 2025-2026 Math (56%) and Reading (51.9%) proficiency and the lowest dropout rate at 2.3%; its graduation rate is 94.4%. Its rank slipped to 76 of 473 (84th percentile, 4 stars) after ranking 10 of 450 the prior year. Zimmerman High School has the highest graduation rate (94.5%) and the highest Science score (45.3%), though its Math (38.6%) falls below the state's 44.9%; its rank has improved to 87 of 473 (82nd percentile, 4 stars). Elk River Senior High is more mixed: its Science score of 39.7% is above the district's 30.1% and the state's 25.5%, but Math (43.1%) and Reading (36.6%) trail the state, and its rank fell from 80th percentile to 64th percentile.
Structure matters: the three comprehensive schools have student-teacher ratios of about 25.8 to 28, while the smaller programs run 7 to 10.2. Ivan Sand Community High School reports a 23.8% graduation rate, a 21.4% dropout rate, and 51.14% free/reduced lunch; its 2024-2025 Math proficiency was reported as 0%. Online728 High School has an 84.0% graduation rate but an 8.0% dropout rate. C.O.M.P.A.S.S. has no rank, test, graduation, or dropout data at all, so it cannot be compared on outcomes. Many values are suppressed by the state — treat those as unknown, not as zero.
