A Federal Pell Grant, unlike a loan, does not have to be repaid. Pell Grants are awarded usually only to undergraduate students who have not earned a bachelor's or a professional degree. (In some cases, however, a student enrolled in a post-baccalaureate teacher certification program might receive a Pell Grant.) Pell Grants are considered a foundation of federal financial aid, to which aid from other federal and nonfederal sources might be added.
How much can I get?
The maximum Pell Grant award for the 2007-08 award year (July 1, 2007 to June 30, 2008) is $4,310. The maximum award for the 2008-09 award year (July 1, 2008 to June 30, 2009) is $4,731. The maximum can change each award year and depends on program funding. The amount you get, though, will depend not only on your financial need, but also on your costs to attend school, your status as a full-time or part-time student, and your plans to attend school for a full academic year or less.
If I am eligible, how will I get the Pell Grant money?
Your school can apply Pell Grant funds to your school costs, pay you directly (usually by check), or combine these methods. The school must tell you in writing how much your award will be and how and when you'll be paid. Schools must disburse funds at least once per term (semester, trimester, or quarter). Schools that do not use semesters, trimesters, or quarters must disburse funds at least twice per academic year.
