Aid to college students has increased by 82 percent over the past decade but still falls short of covering the average price of a college education, as the cost of attending the nation's public universities has continued to outpace inflation, family income, and sources of grant aid, according to two new surveys from the College Board. More than $130-billion in grants, federal loans, Federal Work-Study Program funds, and education tax credits and deductions was distributed to undergraduate and graduate students in the 2006-7 academic year, one of the surveys found, while students borrowed an additional $18-billion from state and private lenders to pay for their educations.
