Idaho and Arizona both take part in Western Undergraduate Exchange. That does not make you an Arizona resident; it caps what a participating campus may charge you. At University of Arizona the cap works out at roughly $20,400 against $41,100.
Seen from Idaho, this is one option among 50. 13 other states offer Idaho residents a reduced undergraduate rate, the lowest being Wyoming at about $10,050, against $9,400 for in-state study at University of Idaho.
Confirm the specific campus takes part. State-level membership is necessary and not sufficient, and several flagship universities either exclude their most competitive majors or sit out entirely.

Arizona residency, in brief
Arizona grants in-state tuition after 12 months of domicile before the term begins (A.R.S. § 15-1802), and a financially dependent student takes the parents' domicile. Moving to Arizona to enroll does not by itself start the clock.
Arizona residency requirements in full · how long every state requires
Step by step
- Check that your chosen Arizona 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. Individual campuses opt in and can cap or close awards — confirm with the school before you apply.
- 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: Arizona grants in-state status after 12 months of domicile, currently $13,600 a year.

- Checked against the administering body
- Compact membership at this level was checked against the commission that runs the program (WICHE).
