Completion outcomes are a standout. Zimmerman High School's 94.5% graduation rate in 2024–2025 is above the district's 89.0% and the state's 84.9%, and its 3.3% dropout rate is below the district's 3.7% and the state's 4.2%. The graduation rate ties Princeton High School for the highest among nearby schools with reported data and tops Elk River Senior High, Online728 High School, and Ivan Sand Community High School. Test scores are more mixed. Science is a clear strength at 45.3% proficiency, above the district's 30.1% and the state's 25.5%, as well as Elk River Senior's 39.7% and Princeton High's 33.7%. Reading, at 50.4%, is above the state's 48.6%, Elk River Senior's 36.6%, and Princeton High's 34.9%, but below the district's 59.3%. Math is the weak spot at 38.6%, below the state's 44.9%, the district's 60.5%, Elk River Senior's 43.1%, and Princeton High's 41.0% — a gap that has recurred over recent years.
About 21.31% of students qualify for free or reduced lunch, lower than Princeton High's 30.21% and Ivan Sand's 51.14% and close to Elk River Senior's 20.55%, while the student–teacher ratio of 25.8 is similar to Elk River Senior's 26.0 but well above Princeton High's 18.2. In 2025–2026, school effectiveness ranked at the 73rd percentile for female students, 79th for male students, and 72nd for low-income students — all 4-star results. Special education ranked at the 32nd percentile with 2 stars, down from the 65th percentile a year earlier, which is the clearest gap to watch, though small groups can swing from year to year.
