What is OSAS?
OSAS is the statewide standardized test administered by Oregon public schools.
What does "% Proficient" mean?
It is the share of students at the school who performed at grade level or above on the test, summed across the top two of four performance levels. A higher number is better.
What does 14.9% mean for English Language Arts at Hauton B Lee Middle School?
It means about 14.9 percent of students tested at Hauton B Lee Middle School performed at grade level or above on the OSAS English Language Arts test in 2024-25. The statewide average for Oregon that year was 43.0%. The other students fell into the lower performance levels.
How is the state average calculated?
It is a weighted average, not a simple average of each school's number. We multiply each public school's score by how many of its students tested, add those together for all schools in Oregon, and divide by the total students tested that year. This way a big school with 1,500 students counts more than a small school with 50 students, which is the right way to ask "how did the typical student do this year?". District and county averages on this page use the same method, just scoped to that district or county.
Where does this data come from?
Oregon Department of Education, Oregon Statewide Assessment System (OSAS) — Smarter Balanced for ELA + Math, OAKS Science. School-level "Total Population (All Students)" subgroup, all grades combined, from the ODE Assessment Group Reports. Headline metric is the cumulative Level 3 + Level 4 rate (SBAC "Met or Exceeded Standard").
How often is it updated?
OSAS is administered once a year (spring). Results are released by the state in the summer or early fall. We refresh this page after each annual release.
