On paper, the Corvallis School District looks like one of Oregon’s academic bright spots;11th out of 141 districts statewide, beating state averages in English, math and science by double digits, a graduation rate seven points above the state’s. But spend an afternoon parsing the numbers for each of Corvallis’ schools, and the story gets messier. What emerges is a maze of wide gaps, a small K-8 campus doing enormous statistical lifting, and two crosstown high schools whose fortunes just swapped places.
Last week, the Oregon Department of Education released its 2026 assessment of schools and school districts statewide. When SchoolDigger aggregates that data, a picture emerges of a Corvallis District that is unmistakably strong by state standards, yet full of internal contradictions that a single ranking number tends to flatten.
Corvallis and the State Compared
Like we said, Corvallis School District 509J ranks 11th of 141 Oregon districts this year, better than 92 percent of them, after slipping two spots from the prior year’s ranking.
Its students post an English proficiency rate of 52.5 percent compared to 43.8 percent statewide. For math, it’s 43.6 percent Corvallis and 32.9 percent statewide. When it comes to science the difference is a whopping 43.4 percent for Corvalis versus 30.6 percent statewide.
90.4 percent of Corvallis’ students graduate, well above the state’s rate of 83 percent. Our chronic absenteeism rate is 30.2 percent; the state’s is 33.5 percent.
By nearly every headline number, in other words, Corvallis is not just above average — and by comfortable margins.
The Franklin effect
But dig one layer down, and a single school is doing an outsized share of the work. That would be Franklin School, the district’s K-8 campus of just 310 students, which the state tucks into the numbers as an “elementary” school for ranking purposes.
Franklin ranks 25th out of 709 Oregon elementary schools — the 96.5th percentile statewide — with an English proficiency rate of 79.4 percent, a math rate of 72.2 percent and a science rate of 61.5 percent. Those are not incremental advantages over the district average; they roughly split the difference between Corvallis’ overall numbers and a perfect score. No other school in the district comes close. The next-best campus, Bessie Coleman Elementary, posts math proficiency of 65 percent and English of 60 percent — solid numbers in their own right, but a full 12 to 20 points behind Franklin.
Franklin serves a student population that looks similar to the rest of the district on paper — 57 percent of students qualify for free or reduced lunch, in line with the district average — which makes its outlier performance harder to explain away as simply a wealthier, easier population. Whatever the reason, statistically, Franklin is functioning like a thumb on the scale: with average scores that far exceed the district’s own average, it pulls Corvallis’ aggregate numbers upward far more than its 310 students — roughly 5 percent of district enrollment — would suggest.
School by school: the elementaries
Beyond Franklin, Corvallis’ nine other elementary campuses (including one small charter) sprawl across a wide performance range — a spread the district’s SchoolDigger profile pegs at 39 to 49 points depending on subject.
Bessie Coleman Elementary sits second in the district and 82nd of 709 statewide; 88th percentile. Like we said, math at 65 percent and English at 60 percent, though its science proficiency, at 50.9 percent, is its comparative weak spot.
Kathryn Jones Harrison Elementary ranks 157th statewide, 78th percentile. English was at 53.4 percent, math at 48.9 percent and science at 51.1 percent — solid, middle-of-the-pack results.
Among the mid-tier in Corvallis; Adams Elementary, ranked 195th of 709 statewide, 72nd percentile, and slipped 20 spots from a year ago.
Letitia Carson Elementary, now closed, was196th, and was also in the 72nd percentile. In its last year, Carson jumped 76 spots in the statewide rankings.
The district’s small charter school, Muddy Creek Charter, tells its own odd story: its science proficiency, 71.4 percent, is the highest of any school in the district, elementary or otherwise — but its math proficiency, 31.4 percent, is the lowest. The school also fell 130 spots in the statewide rankings this year, the sharpest single-school decline in the district, landing at 304th of 709. For this year, they’ve hired a new principal.
At the bottom of Corvallis’ elementary tier sit three campuses — Mt View, Lincoln and Garfield — that anchor the district’s low end.
Mt View is 327th of 709. It posted a science proficiency rate of just 22.7 percent. Lincoln ranked 380th and matched Mtn. View’s science number exactly while posting the district’s second-lowest math score, 38.2 percent, after falling 112 spots from the year before.
Garfield ranks last among Corvallis elementaries, at 406th of 709 statewide — though it was one of the few schools in the district to improve, climbing 11 spots — with English at 40.5 percent, math at 32.8 percent and science at 26.3 percent, all under the district’s own averages and roughly in line with, or just above, the state.
Middle schools and Transition
Corvallis’ two middle schools, Cheldelin, now closed, and Linus Pauling, landed within three spots of each other statewide — but arrived there from opposite directions. Cheldelin ranked 98th of 371 Oregon middle schools, 74th percentile, after a 52-spot fall from a year ago, when it sat at 46th. Its English proficiency, 51 percent, led the district’s two middle schools, but its math score, 36.5 percent, trailed.
Linus Pauling, at 101st of 371 is at the state’s 73rd percentile. The school climbed three spots and posted stronger STEM numbers than Cheldelin; 38.6 percent in math and 43.1 percent in science, against Cheldelin’s 36.5 percent and 40.4 percent, respectively.
Both schools sat comfortably above the state’s middle school averages, but the year-over-year trend lines — one falling sharply, one edging up — suggest a district where middle-grade performance is more volatile than the “11th of 141” district ranking lets on.
Adding to that volatility, the shakeup at Corvallis schools for 2026-27. Elementaries have now expanded to run through grade 6. A two-year junior high has replaced two three-year middle schools. And there has been the almost strange decision to have a near bottom of the district elementary school, Mtn. View, expand to a K-8. The next two years of numbers will be telling.
High schools
Corvallis’ two crosstown high schools effectively swapped places this year.
A year ago, Crescent Valley High School was a clear standout — 20th of 270 Oregon high schools, in the 93rd percentile — while Corvallis High School lagged far behind at 105th. This year, Crescent Valley fell 34 spots to 54th, while Corvallis High School surged 46 spots to 59th — landing the two schools within five places of each other, both now hovering around the upper quintile statewide.
The subject-level detail explains some of the convergence. Corvallis High now leads on 11th-grade English, 60.5 percent to Crescent Valley’s 56.3 percent. Crescent Valley still leads decisively in science, 52.6 percent to 41.6 percent, and edges out Corvallis in graduation rate, 94.1 percent by the district’s account. Neither school’s math proficiency is strong in absolute terms — 34.6 percent at Corvallis High, 31.8 percent at Crescent Valley. Corvallis High also carries the district’s highest chronic absenteeism, at 40.5 percent, in a district that otherwise runs below the state average on that measure.
Corvallis Compared to Albany and Philomath
In education, as in politics, there is the number and there is the direction of the number, and in the mid-Willamette Valley this year the two have rarely pointed the same way.
Take Corvallis, which leads its neighbors in every subject and would seem to have little to worry about. Yet the district’s proficiency rate in English language arts slipped in 2025-26, to 52.5% of tested students, from nearly 55% the year before. It was still the highest mark of the three districts, and it was still a decline. Its math and science scores moved the other way: almost 44% of tested students were proficient in math, and 43.4% in science, both upticks from the previous school year.
Down the road at Greater Albany Public Schools, officials have had more to tout. Nearly 48% of students were proficient in English language arts, up from 43% the year before, a gain of roughly five points that was the biggest single improvement among the three districts. Math climbed too, to just over 32% from 29.5%. Science, however, went the wrong way: 31.7% of tested students were proficient, down from 32.5%. Albany’s math and science rates were the lowest of the three districts.
Then there is Philomath, whose results looked, at first glance, like a study in stasis. In English language arts, 46.6% of tested students were proficient, a hair below the previous year’s 46.8%. In math, roughly 35% were proficient, off from about 36%. But science tells a different story. There, 36.5% of tested students were proficient, a drop of 10 points from 46.5% the year before. That was the steepest fall in the region, and it came in a district that otherwise held nearly steady.
Set side by side, the picture is less a horse race than a set of three diverging trend lines. Corvallis holds the top spot in English, math and science, even as its English scores erode. Albany sits at or near the bottom of the standings but is the only one of the three to improve in both English and math. And Philomath, in the middle on most measures, is defined mostly by what it lost in science.
What the figures cannot say is why. The numbers reflect only students who sat for the tests, and participation rates vary by district and grade, so a rise or fall of a point or two can owe as much to who took the exam as to what students learned. Even so, the results offer a snapshot of a region where the ranking and the momentum tell two different stories.
