More Information about Federal Loans "In the United States both the Federal Family Education Loan Program (FFELP) and the Federal Direct Student Loan Program (FDLP) include consolidation loans that allow students to consolidate Stafford Loans, PLUS Loans, and Federal Perkins Loans into one single debt. This results in reduced monthly repayments and a longer term for the loan. Unlike the other loans, consolidation loans have a fixed interest rate for the life of the loan.
Consolidation loans have longer terms than other loans. Debtors can choose terms of 10–30 years. Although the monthly repayments are lower, the total amount paid over the term of the loan is higher than would be paid with other loans. The fixed interest rate is calculated as the the weighted average of the interest rates of the loans being consolidated, assigning relative weights according to the amounts borrowed, rounded up to the nearest 0.125%, and capped at 8.25%. Some features of the original consolidated loans, such as post-graduation grace periods and special forgiveness circumstances, are not carried over into the consolidation loan, and consolidation loans are not universally suitable for all debtors."

Other lenders will tell you anything to get your loan - not mentioning what might happen later.
The other thing I'd add, however, is that not all consolidation companies are the same. A lot of them sell out the loans they get and leave their customers basically screwed. I've had a good experience with the Educational Loan Company (can't complain with a 2.5 interest rate reduction for prompt payment) but a friend of mine went through a larger competitor and had quite a bit of trouble when they shopped out her loan. This is a huge, dangerous industry that requires a lot of research before you make a decision. Supposedly some reform is planned, but I doubt this will help, other than make it harder for current students to get good rates.
