If professional schools within the University of California want to raise student fees, they might soon be allowed to set new prices by considering what private universities are charging. Current UC policy requires that new fees be no higher than the average cost of comparable public schools. But when UC's regents meet in San Francisco later this month, they will consider changing the policy by removing one word: "public." That's likely going to make the cost of studying medicine, law, business or any number of other careers more expensive - and out of reach for many, say UC graduate students.
