A Stafford Loan is a student loan offered to eligible students enrolled in accredited American institutions of higher education to help finance their education.

Because the loans are guaranteed by the full faith of the US government, they are offered at a lower interest rate than the borrower would otherwise be able to get for a private loan. On the other hand, there are strict eligibility requirements and borrowing limits on Stafford Loans.
Students for a Stafford Loan or other federal financial aid must first complete FAFSA . Stafford Loans are available to students Directly from the United States Department of Education through the Federal Direct Student Loan Program (FDSLP, Also Known As Direct).
No major payments are expected on the loan while the student is enrolled at least half-time, referred to as in-school deferment. Deferment of repayment continuing for six months after the student leaves school by graduating, dropping below half-time enrollment, or withdrawing, referred to as the grace period.
Stafford Loans are available both as subsidized and unsubsidized loans. Subsidized loans are offered to students based on demonstrated financial need. (See Expected Family Contribution .) The interest on subsidized loans is paid by the federal government. For unsubsidized Stafford Loans, students are responsible for all of the increased interest while the student is enrolled in school. The interest may be deferred throughout enrollment. Unpaid interest is deferred until after graduation is capitalized (added to the principal loan).
The Budget Control Act of 2011 eliminated Subsidized Stafford loans for graduate and professional students effective July 1, 2012.  Unsubsidized Stafford loans are still available to students thesis.
Interest rates on Stafford Loans may vary and are based on the date the loan was disbursed. They may also vary by the education level (undergraduate or graduate) of the student. Interest rates do not vary with default risk: all students receive the same interest rate.
