The Bush administration's budget for 2006, due out on Monday, could mean the end of the Perkins loan program. The funds, which are made up of federal \"capital contributions,\" institutional matches, and repaid Perkins loans, are used to make new loans to students from low-income and middle-income families. The president will ask Congress to recall the federal share of institutions' revolving loan funds, according to a top Education Department official. The recalled money would be used to increase the maximum Pell Grant, to eliminate a $4.3 billion shortfall in the Pell Grant program, and to increase loan limits for students in their first two years of college.
