SAN FRANCISCO (AP) - California State University's governing board will vote Wednesday on whether to raise tuition for the first time in six years.

The nation's largest public university system says it needs to hire more faculty and add more classes to accommodate growing enrollment and insufficient state funding.

The proposed annual hikes would increase undergraduate tuition by $270 for the 2017-18 school year at all 23 campuses. The current tuition is $5,472.

CSU said in a statement that nearly 63 percent of California State University undergraduate students, or about 255,000 undergraduates, have their tuition fully covered by financial aid and would not be affected by the increase.
