Relating to: University of Wisconsin System resident undergraduate tuition and fees. (FE)

SB 399 limits annual increases to resident undergraduate tuition at the University of Wisconsin System to the previous year's consumer price index (CPI) inflation rate. This directly affects UW System resident undergraduate students, as their tuition hikes will now be tied to inflation rather than board discretion. The bill defines "resident undergraduate tuition" to include academic fees, differential tuition, and other mandatory fees beyond instructional costs. It creates a new rule requiring the Board of Regents to cap tuition increases at the CPI rate, while maintaining existing policies for non-resident tuition and special programs like summer sessions.
