Summary:
ZIP code 97420, which covers Coos Bay on the Oregon coast, has exactly one middle school: Marshfield Junior High, serving grades 7–8 with 418 students in Coos Bay School District 9. Because it is the only middle school in the area, there are no local peer schools to compare it against — the most useful benchmarks are the district and the state.
Academically, the picture is mixed. 8th-grade science is the standout: 29.5% of students met proficiency, above Oregon's 27.7%, though slightly below the district's 31.2%. 8th-grade ELA is also relatively strong at 39.3%, close to the district (40.9%) and the state (41.5%). Math is the weakest area — 21.2% proficient across all grades, 11.7 points behind the state. The single largest gap is 7th-grade ELA at 28.3%, 17.0 points below the state's 45.3%, while 8th-grade ELA outperforms 7th grade by 11.0 points. The school trails its own district in every reported assessment category, usually by only 1 to 2 points.
Chronic absenteeism is the clearest concern: 44.1% of students are chronically absent, compared with 40.4% in the district and 33.5% statewide — 10.6 points above the state. The school holds a 2-star rating and ranked 251 of 371 Oregon schools in 2025–2026, placing it in the 32nd percentile, down from the 44th percentile the prior year. It also reports 39% free/reduced lunch, $7,092 in per-student spending, and a 20.9:1 student-teacher ratio. Overall, families should know this school shows real strengths in 8th-grade science and ELA, but has meaningful ground to make up in math, 7th-grade reading, and attendance.
