The University of North Carolina Board of Governors has adopted a policy that will bar the UNC system's campuses from spending more than 15 percent of tuition revenue on financial aid, The News and Observer reported. Six of the system's campuses -- including UNC Chapel Hill and North Carolina State University -- currently spend larger proportions of tuition revenue on student aid. Officials at Chapel Hill, which has devoted considerable resources to expanding aid for low-income students, have predicted that the policy will lead to considerable increases in student debt levels. Proponents of the policy have said that the policy will limit tuition increases, and that such limits help all students. University officials have said that they plan to try to raise more money so that they can pay for financial aid that would be limited under the new policy.
