Miller High School has a low student-teacher ratio of 10.4—second only to Trimble High School’s 10.1—and per-student spending of $10,942 in 2018–2019, above most nearby districts except Trimble. Yet its outcomes are among the lowest in the area. Subgroup ranks for female, male, and low-income students were all in the bottom quartile. Miller’s results are similar to Crooksville High School and Nelsonville-York High School, while Morgan High School, New Lexington High School, Athens High School, and Logan High School generally perform better. Logan and Athens show stronger outcomes are possible nearby. Because Miller High School is small, year-to-year swings can be amplified, so families should look at multiple years. The pattern suggests focusing on instructional alignment, attendance, and targeted academic interventions rather than simply adding resources.
