Summary:
Riverdale Local has one high school, Riverdale High School, in Mt Blanchard, Ohio, serving grades 9–12 with 321 students. Because it is the only high school in Riverdale Local, its results largely represent the district’s high-school outcomes. The district is ranked 448 of 773, or 42nd percentile with 2 stars, while the school is currently ranked 465 of 795, also 42nd percentile with 2 stars.
Academically, Riverdale High School is stronger in social studies and English than in math. In 2025–26, American History was 80.4% proficient versus 73.2% statewide, American Government was 78% versus 71.6%, English II was 67.5% versus 62.7%, and Biology was 67.5% versus 67%. Math is the clear weakness: Algebra I was 45.1% proficient versus 61.6% statewide—a 16.5-point gap—and Geometry was 37.5% versus 43.3%. From 2024–25 to 2025–26, Biology and Geometry improved, but American Government and Algebra I declined sharply. Averaging the six End-of-Course subjects, the school slipped from slightly above the state in 2024–25 to slightly below it in 2025–26.
Other important factors: the 2025–26 graduation rate is strong at 97.0%, matching the district. However, chronic absenteeism is 30.8% at the school versus 16.2% for the district—nearly double and a major concern. Free/reduced lunch participation is 99.07%, the student-teacher ratio is 21.4, and 2018–19 per-student spending was $10,014. The school’s rank has been volatile, moving from 2 stars in 2023–24 to 3 stars in 2024–25 and back to 2 stars in 2025–26. For parents, the most actionable concerns are Algebra I proficiency and chronic absenteeism, even as social studies, English, and graduation outcomes remain strengths.
