Students at the University of Saskatchewan will have to dig deeper into their pockets in the next school year.

The university's board of governors has approved tuition increases averaging 4.5 per cent.

Tuition for an arts and science student will increase $218 to just over $5,400, but other programs -- including engineering, law and medicine -- will see bigger increases.

Tuition makes up 23 per cent of the university's operating budget.

The tuition increase comes as the university projects a deficit of $44.5 million by 2016 if no action is taken to save money.

But board of governors chairwoman Susan Milburn says the school hasn't raised tuition rates to balance the budget.
