Tuition for in-state undergrads at UNC Chapel Hill is going up a few hundred bucks next year.

Not coincidentally, the deductible for one of Duke University's most popular employee perks will likely go up the same amount.

Duke's Children's Tuition Grant program, which covers much of the cost of college for the children of employees, generally doesn't cover the cost of a public university education in North Carolina. That's because Duke sets a deductible about at the tuition rate in-state students pay to attend the UNC system's flagship, UNC-Chapel Hill.

With tuition going up $313 next year over at Carolina, the Duke deductible will probably go up as well to meet it, said Kyle Cavanaugh, Duke's human resources vice president.

The point here: If you work at Duke and have a child going to UNC-CH or another public university, Duke won't help pay.

But if you go to a more expensive college in North Carolina or elsewhere, Duke will help out - considerably. Duke's tuition grant program will cover your child's college tuition, up to 75 percent of Duke's tuition, minus the deductible.

This year, the yearly deductible is $4,816.

What it all means: If your college is expensive enough, Duke will cover up to $14,000 a semester. Students are eligible if a parent has worked full-time at Duke for five years. It maxes out at eight semesters and there's a two-child limit.

About 1,100 employees receive the benefit this year, Cavanaugh said, adding that over the years, it has proven a valuable tool to lure employees.

"It's very much a recruitment and retention issue for us," he said. "It's clearly one of the most valuable benefits we have."
