Summary:
ZIP code 46785 contains exactly one elementary school: Riverdale Elementary School, a K–6 school with 300 students located at 6127 Sr 1 in Saint Joe, Indiana. It is the only elementary school in the area, so there is no other local school to compare it with; instead, it is best measured against its district and the state. The school belongs to the DeKalb County Eastern Com School District, which is rated 3 stars and sits at the 58th percentile statewide, making Riverdale a relative strength within its own district.
Riverdale has earned 4 stars in each of the last three school years, with a state rank of 251 out of 1,015 schools in 2025–2026 — the 75th percentile. That is slightly below its 2023–2024 peak of the 80th percentile, but still solidly top-quartile. In 2025–2026 the school outperformed its district in every reported all-grade subject: ELA at 45.34% versus 33.74%, Math at 54.66% versus 38.17%, and Science at 58.67% versus 38.02%. Several upper-grade results stand out, including 5th grade Social Studies at 77.27%, 5th grade Math at 68.18%, 4th grade Math at 66.67%, and 6th grade Science at 60%. Chronic absenteeism is a notable strength: 6.7% at Riverdale, compared with 14.6% for the district and 16.7% for the state.
Two areas are worth watching. In 2025–2026, 3rd grade Math was 38.1%, slightly below the district’s 39.09% and well below the state’s 51.9% — the only grade-level result below both. All-grade Science also slipped from 64.63% in 2024–2025 to 58.67% in 2025–2026, though it remains far above the district. For context, Riverdale enrolls 300 students, has a 41.67% free/reduced lunch rate, spends $10,838 per student, and has a 17.8 student-teacher ratio.
