Best Public Schools in Mill City, OR

Mill City, Oregon has three listed schools — Oregon Charter Academy (K–12), Santiam Junior/Senior High School (6–12), and Santiam Elementary School (K–5) — all within Santiam Canyon School District 129J, with no separate middle school, so grades 6–8 are served at the junior/senior high. Total listed enrollment is 2,913, but the distribution is very uneven: Oregon Charter Academy enrolls 2,345 students, or about 80.5% of the total, making it more than four times larger than the other two schools combined.

Academically, the three schools look very different. Oregon Charter Academy posts the strongest all-grade results in English language arts (50.3%), math (44.0%), and science (47.9%), all above district and state averages, with especially strong 11th-grade scores. However, its graduation rate is 80.2%, below the district's 81.7% and the state's 83.0%, and its chronic absenteeism (37.2%) is above the state's 33.5%. Santiam Junior/Senior High School shows the opposite pattern: the highest graduation rate in the group at 93.2%, but a statewide rank of 270th of 271 (0th percentile, 0 stars), with ELA at 15.7%, math at 13.3%, and science under 5%. Santiam Elementary School has one clear bright spot — 3rd-grade math at 51.6%, above both district (50.5%) and state (41.3%) — but sits below state in ELA and science, and ranked 448th of 709 (37th percentile, 2 stars).

Several broader patterns stand out. Chronic absenteeism is above the state rate of 33.5% at every school: 37.2% at the charter, 39.4% at the junior/senior high, and 43.2% at the elementary, which is nearly 10 percentage points above the state. Reported per-student spending does not track simply with outcomes — $1,608 at Oregon Charter Academy, $14,782 at the elementary, and $17,973 at the junior/senior high. Both Santiam schools report free/reduced lunch rates near 81%, indicating high economic need, while the charter's free/reduced lunch figure is not provided. Some values are suppressed or bounded, such as science under 5% at the junior/senior high, and should be read as bounds rather than exact figures.
