Summary:
ZIP code 97048 has just one public high school option: Rainier Junior/Senior High School in Rainier, Oregon, part of Rainier School District 13. It is a combined junior/senior high serving grades 7–12 with 366 students, so state test results cover grades 7, 8, and 11 rather than high school grades alone. Nearly 79% of students qualify for free or reduced-price lunch, per-student spending is $21,636, and the student-teacher ratio is 16.6. District results for English Language Arts, math, and science match the school's results at every reported grade, which suggests this school drives most of the district's secondary-level data.
The clearest strengths are in science and 8th grade English. All-grade science proficiency is 35.2%, above Oregon's 30.6%, and both 8th grade science (35.6% vs. 27.7%) and 11th grade science (34.5% vs. 33.8%) beat the state. Eighth grade English Language Arts is the standout at 57.6% proficient, well above the state's 41.5%. Eleventh grade math is also slightly ahead of the state at 24.1% versus 22.9%, though that is still low in absolute terms.
The challenges are significant. Seventh grade English is only 8.9% proficient against a state rate of 45.3% — a striking contrast with 8th grade in the same building. All-grade math sits at 22.9% versus 32.9% statewide, and 7th and 8th grade math both trail the state. The graduation rate is 62.2% compared with Oregon's 83.0%, and chronic absenteeism is 48.6% versus 33.5%. The school's rating also slipped, from 93 of 270 (3 stars) in 2024–2025 to 140 of 271 (2 stars) in 2025–2026. Overall, this is a mixed profile: real strength in science and 8th grade reading, with math, 7th grade reading, attendance, and graduation as the areas most in need of attention.
