Idaho and California both take part in Western Undergraduate Exchange, but not every California campus does, and University of California, Berkeley is one that does not. There an Idaho resident pays the $49,600 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.

California grants in-state tuition after 12 months of domicile before the term begins (Cal. Educ. Code § 68017), and a financially dependent student takes the parents' domicile. Moving to California to enroll does not by itself start the clock.
California residency requirements in full · how long every state requires
Step by step
- Check that your chosen California 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 California, Berkeley is not on WICHE's WUE list. The figure applies the 150% cap to its resident rate for scale only; 24 other California 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: California grants in-state status after 12 months of domicile, currently $15,900 a year.
