Funding

How Oregon funds schools

Oregon funds districts through the State School Fund, distributed by an equalization formula based on weighted average daily membership (ADMw): a standard student counts as 1.0, with added weight for special-education, English-learner, poverty, foster and other high-need students, and the state grant rises as a district’s local property-tax revenue falls. The 2025–27 budget set the fund at a record $11.36 billion.

District-level per-pupil spending and the local/state/federal revenue split for Riverdale SD 51J are published in the federal school-finance files — see the full-data links below for the current figures.

Accountability

Report card & state results

Oregon publishes At-A-Glance School and District Profiles rather than letter grades, comparing each district to the statewide average on attendance, graduation and completion, state test results and demographics. Look up Riverdale SD 51J on the Oregon At-A-Glance Profiles.

Accreditation

Accreditation status

Oregon holds public districts to its own Division 22 standards (OAR Chapter 581) enforced by the Department of Education, rather than requiring a private accreditor. See the Oregon Department of Education for a district’s standards status.
