Original Research by School Decision on Mill Valley Elementary School
Mill Valley Elementary School serves students from pre-kindergarten through fourth grade in Marysville, a county seat about half an hour northwest of Columbus that is experiencing rapid residential growth. The school enrolls a small-to-moderate student body with a demographic profile that is predominantly white, though with meaningful representation across Hispanic, Black, Asian, and multiracial backgrounds. About three in ten students qualify for free or reduced-price lunch, and the school participates in Title I programming, indicating a mixed-income enrollment.
On state testing for grades three and four, Mill Valley's proficiency rates are solidly above midpoint among Union County's districts. In math, roughly three-quarters of tested students scored at proficient or above, with an average scale score in the middle range. English language arts proficiency is somewhat lower at about two-thirds, reflecting a gap that many elementary schools experience between math and reading performance. Both subject results place the school above the county median on a proficiency index. A social studies assessment from 2016-17 (the most recent available for this grade band) showed very strong performance, though more recent trend data in that subject is not available for elementary grades in Ohio. State participation rates in tested subjects are complete, showing strong attendance on assessment days.
The school's physical location at Mill Wood Boulevard places it on a separate campus outside Marysville's walkable downtown core; the area is car-dependent, consistent with much of suburban Marysville. Families here are likely navigating the effects of the district's recent budget challenges and the property-tax levy that passed in May 2025, after two prior rejections. Before that levy succeeded, the district had cut roughly two dozen teachers and eliminated school resource officers, changes that affect school safety resources and staffing. The May 2025 levy has stabilized funding and brought back some positions, but extracurricular pay-to-participate fees remain elevated from their pre-2024 levels. Families considering Mill Valley should be aware of the tax implications on their property purchase and the staffing trajectory in the district.
The broader context is significant: Marysville and Union County are among the fastest-growing areas in Ohio, with substantial new housing development underway and the district adding students at a steady rate each year. Honda's manufacturing and development operations, along with companies in the automotive supply chain, anchor the local economy. That growth creates both opportunity and strain. For families choosing this school, the reading is of an elementary program with solid core academic results, serving a mixed-income and increasingly diverse community in a district working to absorb rapid enrollment growth while rebuilding its budget after temporary austerity.
