Summary
Highland High School is a grades 9–12 school in Marengo, Ohio, serving 468 students in the Highland Local district. In 2025–2026 it ranks 431 of 795 in Ohio (46th percentile, 2 stars), slightly below the state midpoint and below most nearby traditional high schools; the district ranks 371 of 773 (52nd percentile, 3 stars). Schools such as Northmor High School, Big Walnut High School, Centerburg High School, Fredericktown High School, Mt Gilead High School, Mount Vernon High School, and Northridge High School rank higher, while Cardington-Lincoln High School and Tomorrow Center rank lower.
The school’s academic profile is uneven. American History is a clear strength: 88.9% proficiency versus 73.2% statewide, with Biology at 78.0% and American Government at 76.3%, both above the state’s 67.0% and 71.6%. Math is the biggest weakness: Algebra I is 35.1%, far below the state (61.6%) and the district (52.7%), and Geometry is 33.3%, below the state (43.3%) and district (40.8%). English II is 65.6%, only modestly above the state’s 62.7% but below almost every nearby traditional high school except Cardington-Lincoln High School. Centerburg High School and Fredericktown High School, for example, post much stronger math and English II results.
Graduation is strong at 96.4%, and chronic absenteeism improved from 31.5% in 2021–2022 to 17.7% in 2025–2026, though it remains above the district rate and higher than Centerburg High School, Fredericktown High School, and Mt Gilead High School. The student-teacher ratio improved to 13.7, but per-student spending was $8,479 in 2018–2019, the lowest among nearby schools with reported data, and free/reduced lunch rose from 21.71% to 35.26%. Subgroup results vary: female students rank at the 48th percentile, male students 37th, special education 47th, low-SES 50th, and gifted students 23rd. Overall, the school’s rank slipped from the 58th percentile in 2022–2023 to 46th in 2025–2026. The most actionable priorities are Algebra I, Geometry, and English II, while preserving strengths in American History and Biology and continuing to reduce absenteeism.
