California students have struggled (without much success) to win tuition freezes in public higher education. Now a graduate of the University of California at Irvine is trying a new tactic that could succeed where others have failed. He is collecting signatures on a petition for a referendum to the California Constitution that would require public colleges and universities to keep tuition rates at the level that students pay when they first enroll, The Los Angeles Times reported. So colleges and universities could increase the rates each year for new students, but not continuing students. "It's an unsettling and uncertain feeling when you think you are going to afford something and just skate by and suddenly somebody asks for more money you don't have. You feel you are going to lose your investment. You feel you are going to lose your future," said Christopher Campbell, who is organizing the campaign. California higher education leaders are skeptical, and Campbell still needs many more signatures. But such a proposal, if it qualifies for the ballot, could be popular.
