The Pell Grant is a federal grant that does not have to be repaid, as long as you meet the eligibility requirements and use the money for educational purposes.
To maintain your eligibility for the Pell Grant, you must be making satisfactory academic progress and using your grant funds for qualified educational expenses, such as tuition, fees, books, and supplies.
You can find more information about the Pell Grant and its requirements on the Federal Student Aid website.
