Consolidation of loans allows a borrower to combine different types of federal student loans to simplify repayment. You can even consolidate just one loan into a Direct Consolidation Loan to get benefits such as flexible repayment options. Because consolidation programs vary, refer to the 2007/2008 Student Guide to Financial Aid Form from the U.S. Department of Education, pages 33-35.
