Amounts can change yearly. The maximum Federal Pell Grant award is $5,730 for the 2014–15 award year (July 1, 2014, to June 30, 2015). For the 2015–16 award year (July 1, 2015, to June 30, 2016), the maximum award will be $5,775.

your plans to attend school for a full academic year or less.

Effective on July 1, 2012, you can receive the Federal Pell Grant for no more than 12 semesters or the equivalent (roughly six years). You’ll receive a notice if you’re getting close to your limit. If you have any questions, contact your financial aid office.
