Students at the University of California and the California State University are already facing tuition increases for the fall semester. But new state budget cuts passed this week could mean an additional mid-year hike — and that’s if everything goes according to plan with the budget from here on out.

Tuition has more than tripled in California in the last decade, and fees are slated to rise another 8% at CSU and 10% at UC in the fall semester. State legislators just cut an additional $150 million each from UC and CSU, compounding a combined cut of $1 billion planned this spring. In total, the reductions amount to a more than 20% cut from just least year.

The just-passed budget assumes new revenues of $4 billion for the state which have not yet been approved. If those funds fail to materialize, UC and CSU stand to lose another $100 million each.
