Summary

Ione Elementary serves 564 students in kindergarten through grade 6 in Ione, California, in Amador County Unified. Its most important challenge is English language arts (ELA): in 2025–2026, 23% of students were proficient, 26 percentage points below the state and 9 below the district. That was the lowest ELA rate among seven nearby K–6 schools with results.

ELA is Ione’s clearest weakness compared with both local peers and larger benchmarks. Math proficiency was 20%, below the state and district and the second-lowest among those nearby K–6 schools. Science is the relative bright spot: 24% proficiency was closer to the state and district rates than Ione’s other subjects, and near the nearby-school average of 27%; Ione ranked in the middle of the eight-school group. Still, science remained below both the state and district. Within the grades reported, third-grade ELA was especially low at 11%, while fifth-grade math was Ione’s weakest grade-and-subject result at 15%.

ELA and math have weakened over the four years shown: ELA fell 4 percentage points overall, and math fell 2, while science gained 9 points despite dropping 7 from its 2024–2025 peak. Ione also fell from the 24th to the 14th statewide percentile in SchoolDigger’s rankings, receiving 1 star in 2025–2026; the district ranked in the 24th percentile, also with 1 star. SchoolDigger’s Special Education Students subgroup ranking stands out: the 41st percentile, 27 points above the school’s overall ranking, indicating a notably stronger ranking for how well the school serves this group. The student–teacher ratio was 25:1 in 2024–2025, compared with a nearby-school average of 23.2:1. In that same year, 34% of students were free/reduced lunch eligible.
