We have the standard in-state tuition rate that is lower than out-of-state rates for public schools.
We also have the Oregon Office of Student Access and Completion, which administers the Oregon Opportunity Grant to financially needy students. It's not a ton, but it's enough to be significant and help. If you qualify based on need, you get the full grant (there's no sliding scale) which is currently $2100 a year. This is for public or private schools.
There's also the OSAC suite of scholarships open to Oregon residents, but they're just like standard merit/need scholarships just with a smaller pool. Also for public and private schools.
