The Free Application for Federal Student Aid (FAFSA) is a form that students in the United States fill out to apply for financial aid for college. This application helps determine eligibility for federal grants, loans, and work-study programs. Completing the FAFSA is essential for students seeking financial assistance to help cover tuition and other educational expenses. Submitting the FAFSA is free and can be done online. It requires information about the student's and their family's financial situation, including income and assets. Many states and colleges also use the FAFSA to award their own financial aid, making it a crucial step for students seeking funding for their education.
