Best Middle Schools in Zip Code 43015

ZIP code 43015 in Delaware, Ohio is served by three public middle schools across three different districts — John C Dempsey Middle School in Delaware City (grades 6–8, 1,278 students), Olentangy Berlin Middle School in Olentangy Local (grades 6–8, 886 students), and Buckeye Valley Local Middle School in Buckeye Valley Local Schools (grades 5–8, 612 students). Together they enroll 2,776 students, and families here have a genuine range of options rather than one neighborhood school.

Olentangy Berlin Middle School is the clear standout: 37th of 1,046 middle schools statewide, 5 stars, and 96th-percentile ranking three years running, with the lowest chronic absenteeism in the group at 6.3%. Buckeye Valley Local Middle School is the biggest riser, climbing from the 73rd to the 82nd percentile and improving in 7 of 10 tested areas — including 7th-grade math jumping from 42.2% to 60.7%. John C Dempsey Middle School is the largest but lowest ranked at the 66th percentile and 3 stars, trending down over three years, though its 8th-grade math (78.6%) beats both other schools.

The main concern is Dempsey's 6th-grade math at 41.2%, the only result below the state average (56.2%) in 2025‑26, with its gap widening from −0.9 to −15.0 points. Otherwise, poverty and absenteeism track achievement closely across all three schools: Berlin at 11.6% free/reduced lunch and 6.3% absenteeism, Buckeye Valley at 24.2% and 14.5%, and Dempsey at 37.5% and 21.0%. Berlin also posts the largest classes (20:1) with the best results, so class size alone doesn't predict outcomes. Note that spending figures are from 2018‑19 and missing for Berlin, and with only three schools these comparisons are descriptive, not definitive.
