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 a student's eligibility for federal grants, loans, and work-study programs. Completing the FAFSA is essential for accessing various types of financial assistance, including funds from state governments and individual colleges. To complete the FAFSA, students need to provide information about their family's financial situation, including income and assets. The application is available online and must be submitted annually, typically starting on October 1st each year, to ensure timely consideration for aid for the upcoming academic year.
