Idaho and Washington both take part in Western Undergraduate Exchange, but not every Washington campus does, and University of Washington is one that does not. There an Idaho resident pays the $43,000 non-resident rate. At the campuses that do participate, tuition is capped at 150% of each school's own resident rate.
The comparison that matters is with home: University of Idaho charges an Idaho resident $9,400 a year. 13 other states offer Idaho residents a reduced undergraduate rate, the lowest being Wyoming at about $10,050.
Before you count on it, check three things with the campus directly: that it participates this year, that your major is covered, and when its award deadline falls. All three change annually and none of them are set by the state.

Washington residency requirements in full · how long every state requires
Step by step
- Check that your chosen Washington campus participates in Western Undergraduate Exchange — membership is a state-level agreement, but each campus decides whether to offer it and how many awards to fund.
- Confirm your intended major is on the approved list. University of Washington is not on WICHE's WUE list. The figure applies the 150% cap to its resident rate for scale only; 9 other Washington campuses offer WUE, each capped against its own resident rate.
- Apply for the award at the same time as admission, and well before the campus deadline — most participating institutions award on a first-come basis and close early.
- Keep your Idaho residency documentation current; the program is only open to residents of a member state.
- Compare the result against the residency route: Washington grants in-state status after 12 months of domicile, currently $12,900 a year.
