Summary:
Jefferson, Oregon is served by Jefferson School District 14J, a small K–12 district with three schools and 695 students total: Jefferson Elementary School (K–5, 272 students), Jefferson Middle School (6–8, 178 students), and Jefferson High School (9–12, 245 students). No alternative schools are listed. The district ranks 137th of 141 in Oregon — the 3rd percentile, with 0 stars — and all three schools share that district rating.
Among the three, Jefferson Elementary is the relative bright spot, with the highest all-grades proficiency: 30.6% in English language arts, 14.3% in math, and 17.8% in science, all below the state's 43.8%, 32.9%, and 30.6%. Its 3rd-grade ELA score of 41.5% exactly matches the state. Jefferson Middle has the highest student-teacher ratio (41.2) and the lowest science proficiency (8.3%); its 6th-grade math is under 5%, compared with 29.7% statewide. Jefferson High is the paradox school: its 84.5% graduation rate is above the state's 83.0%, yet 11th-grade ELA is 17.3% vs. 46% and math 7.7% vs. 22.9%. Its ranking also fell sharply, from the 66th percentile with 3 stars in 2023–2024 to the 7th percentile with 0 stars in 2025–2026.
Across the district, math is the weakest subject, and chronic absenteeism exceeds the state rate of 33.5% at every school: elementary and middle are tied at 40.1%, while high school is 51.3%. About 75% of students qualify for free or reduced lunch, and per-student spending ranges from $17,407 to $21,337. Spending alone does not appear to be lifting proficiency, and no test-score values in this data set are suppressed.
