Most grant programs are only available for undergraduate students and have limits on the number of semesters in which a student can receive funds. For most, the maximum is between four and five years. The Federal Pell Grant program limit is 600% (the equivalent of six years at full-time). More information on limits can be found in each individual program listed in Types of Aid.
Most loan programs have imposed limits on how much can be borrowed for an academic year as well as how much can be borrowed for an entire career (aggregate career limits). Learn more about direct loan limits here.
Undergraduates can attempt up to 150% of the credits needed to complete their degree before they will no longer be eligible for aid. Graduate students are able to attempt 200% of their required credits. Review the Satisfactory Academic Progress Policy for details.
