Summary:
Zionsville's 46077 ZIP code is served by seven public schools — five PK–4 elementaries, one 5–8 middle school, and one 9–12 high school — all belonging to a single district, Zionsville Community Schools, which ranks #8 of 374 Indiana districts (98th percentile, 5 stars) and enrolls 6,287 students in total. The structure is a straight pipeline: five elementaries feed one middle school, which feeds one high school, with the unusual twist that grade 5 sits in the middle school building rather than the elementaries.
Two elementaries stand out statewide. Zionsville Pleasant View Elementary School ranks #5 of 1,015 Indiana elementaries and leads the area in nearly every measure, including 2025–26 ELA of 79.73%, Math of 87.04%, and Science of 86.75%. Union Elementary School ranks #26 of 1,015 while posting the lowest free/reduced lunch rate (2.87%) and lowest chronic absenteeism (2.2%) in the area. Zionsville Community High School ranks #6 of 415 high schools with a 97.9% graduation rate (state: 89.7%) and SAT Math proficiency of 64.37% versus the state's 25.6%. Zionsville Middle School has climbed steadily (#20 → #10 → #9). Trailside Elementary School, Stonegate Elementary, and Eagle Elementary School rank #130, #132, and #137 of 1,015 — still 87th percentile.
Every school here beats the state in every reported subject, so the real story is variation beneath that ceiling. Elementary math proficiency runs higher than ELA everywhere, but Trailside's gap is 24.1 points (Math 76.89% vs. ELA 52.83%) — more than triple Pleasant View's 7.3 points. All five elementaries declined in both ELA and math year over year, which looks like a cohort effect rather than one school's problem. Spending doesn't track achievement: the two highest-spending elementaries land at #137 and #5. Absenteeism rises with grade level, and the high school's 8.8% is the only rate meaningfully above the 5.5% district average, even as it posts top-1% outcomes.
