Lisa Scott of Sparrows Point has seen young relatives graduate from college and struggle to keep up with $100,000 in education debt.

"Their current jobs do not allow them to pay that debt" said Scott, area marketing director for Chick-fil-A in Maryland. "The stress on them is horrific and so much, when it should be the most exciting time of their life, coming out of college and ready to take a bite out of the world."

Scott, 48, doesn't want the same to happen to her 7-year-old daughter Lilly.

A couple of years ago, Scott started putting $4,500 away annually in Maryland's prepaid tuition plan, which allows families to pay in advance for college based on today's prices at the state's public colleges. And given Lilly's interest in becoming a veterinarian, Scott said she and her fiance will start setting aside even more next year.

According to an annual study released last week by Fidelity Investments, 69 percent of parents of have started to save for college, the highest percentage since the Boston-based mutual fund company began polling families in 2007. Back then, 58 percent of parents saved for college.

"The economy has been getting better. People are on a more solid foundation," said Keith Bernhardt, Fidelity's vice president of college planning.

At the same time, he said, parents have heard stories of students burdened by steep debt and are trying to prevent that happening to their own kids.

But many parents still aren't saving enough. Parents said they plan to pay 62 percent of the total cost of college, but Fidelity found they were on target to meet only one-third of that goal. Families on average set aside $5,000 last year.

The Fidelity study is based on a survey of more than 2,500 families nationwide whose children are age 18 and younger and expect to attend college.

Caroline Bright, director of financial aid at McDaniel College, said she has noticed a change among parents and students.

"They are more cautious about borrowing," Bright said. "Maybe all the negative press about students and parents getting over their head on student loan borrowing has made families more aware of the need to save."

Big tuition bills are weighing on parents' minds.

"I have a rising [high school] senior and a rising junior. I lose sleep at night," said Tim Hayden, coordinator of the office of school counseling for Baltimore County's public schools. He also has a daughter who is in seventh grade.

Hayden and his wife started saving each month for college in mutual funds when their first two children were very young. But the couple's salaries back then were lower, and they weren't able to salt away enough to keep up with today's steep tuition, said Hayden, who recently visited colleges with his sons.

Out-of-state public schools can be around $40,000 a year, he said, while private universities run $50,000 annually or more.

Hayden, 50, figures he might take out a home equity loan to finance college, and his sons might have to use student loans.

Nearly three-quarters of families polled by Fidelity thought college was becoming cost-prohibitive.

Megan Fichter, an Ellicott City mother of three, agreed.

"I don't understand how you could possibly save enough without starting when they are young," said Fichter, 39, a stay-at-home parent.

Thanks to an inheritance, she and her husband prepaid tuition for their 7-year-old son using the Maryland Prepaid College Trust plan. They set aside $200 each month in the state's other savings vehicle, the College Investment Plan managed by T. Rowe Price, for their 5-year-old daughter.
