Summary:
ZIP code 45859 in Mc Guffey, Ohio, is home to three public schools — Upper Scioto Valley Elementary School (K–6, 257 students), Upper Scioto Valley Middle School (7–8, 54 students), and Upper Scioto Valley High School (9–12, 159 students) — all belonging to the single Upper Scioto Valley Local district and sharing one campus, with roughly 470 students in total. The district as a whole ranks 517th of 773 Ohio districts, putting it in the 33rd percentile with a 2-star rating.
Performance is strongest at the ends of the grade range and weakest in the middle. The high school posts the top result in the area — Biology at 81.6% proficient, 14.6 points above the state — and also beats the state in American Government, American History, and English II, with a 96.6% graduation rate. The elementary school's grades 4, 5, and 6 math scores beat the state in both of the last two years, including 78.1% in 4th-grade math. The middle school is the clear weak spot: none of its five tested subjects met the state average in 2025‑26, averaging 43.6% against a 56.6% state mark, and its 8th-grade science fell from 53.8% to 28.6%, more than 32 points below the state.
Two gaps deserve attention. High school Geometry dropped to 19.5% proficient — 23.8 points below the state and far beneath the school's own Biology score — while Algebra I (59.3%) also trails the state. And 3rd-grade math is the elementary school's weakest measure in both years, even as grades 4–6 math shines. Chronic absenteeism is highest at the high school (19.2%) and nearly identical at the middle and elementary schools (15.6% and 15.3%). Note that the middle school's 54:1 student-teacher ratio is an extreme outlier next to the elementary (15.1) and high school (13.2) and likely reflects a reporting or shared-staffing quirk, and that per-student spending figures date to 2018‑19. With small grades of about 27 students, a few children can move a percentage sharply, so single-year swings should be read with caution.
