Amid loud student protests that roiled the UCLA campus, the UC Board of Regents this afternoon approved a 32% increase in student fees.

The fee hike of $2,500, or 32%, will come in two steps by next fall. That would bring the basic UC education fees to about $10,300, plus about another $1,000 for campus-based charges, for a total that would be about triple the UC cost a decade ago. Room, board and books can add another $16,000.

Only student regent Jesse Bernal voted against the undergraduate fees.

The noise of protesters came through the window as the regents voted. It was only lightly discussed, with UC President Mark G. Yudof urging that students explore all the financial-aid possibilities so they don’t get scared away or drop out.

Groups of UC students from several other campuses arrived in Westwood to join a demonstration against the fee hike, and a group of protesters was occupying a UCLA classroom building.

UCLA officials declared Campbell Hall, where the sit-in continued, closed for the day. Inside, about 40 to 50 students who had chained the doors shut shortly after midnight were issuing e-mail statements.

“We choose to fight back, to resist, where we find ourselves, the place where we live and work, our university,” their statement said. Campus police surrounded the classroom building, but no arrests were made.
