Summary:
ZIP code 45227 contains six schools — three elementary, two middle, and one high school, with no alternative schools — split between two districts that produce very different results, and together they enroll about 1,761 students. The Mariemont City schools account for roughly 1,225 students (about 70% of the ZIP's enrollment), while the Cincinnati Public Schools schools account for 536 (about 30%). Grade spans overlap across the area: Bramble School serves PK–8, John P. Parker School serves PK–6, Shroder Middle School serves 5–8, Mariemont Elementary School serves K–6, Mariemont Junior High School serves 7–8, and Mariemont High School serves 9–12.
The Mariemont City district ranks 6th of 773 in Ohio, at the 99th percentile, with 5 stars, and all three of its schools earn 5 stars. Mariemont Junior High School is the strongest school in the ZIP, ranking 4th of 1,046 middle schools at the 100th percentile, with 100% proficiency in Algebra I and Geometry EOC in both 2025–2026 and 2024–2025, plus 99.2% in 7th-grade ELA and 97.3% in 7th-grade math. Mariemont High School ranks 6th of 795 high schools and posts a 98.1% graduation rate. Mariemont Elementary School ranks 42nd of 1,560 elementary schools, in the top 3% of the state.
The contrast within the ZIP is sharp. John P. Parker School ranks 1,164th of 1,560 with 1 star and 42.7% chronic absenteeism, while Shroder Middle School ranks 950th of 1,046 with 0 stars, 7th-grade math at 6.1% and 8th-grade math at 11.1%. Bramble School is the surprise: a CPS school ranked 232nd of 1,560 with 4 stars, 7.5% chronic absenteeism against a district rate of 44.6%, and ELA scores of 100% in grades 3 and 6 — though with only 34 students its percentages can swing widely. Free/reduced lunch and spending figures are missing for several schools, so those comparisons are limited.
