Speak with your guidance counselor if you are in high school or your financial aid office if you are in college. Such experts know about a variety of college funding options and can help match you to the best options based on your circumstances. Even if they can't help you, they should be able to direct you to the right places to start searching.
See whether your federal government offers any grants for college students. For example, the U.S. Federal government offers the Pell Grants to help students in need. Furthermore, if your grades are good, you might qualify for an Academic Competitiveness Grant. You can apply for that grant by filling out the online Free Application for Federal Student Aid.
See if other tiers of government offers any grants for college students. You'll have the best chance of success by first checking with your state or provincial government. State governments in the U.S. often list possible college grants on the websites for their education departments.
See whether your parents' employers offer any grants for college students. Many companies (AT&T and Coca-Cola, for example) offer grants for the children of their employees who are headed off to college.
Use a service like Grants.gov to search for grants to which you can apply. Because grants are given out based on all kinds of miscellaneous criteria, you may need to narrow your search using search engines. For example, the federal National Science and Mathematics Access to Retain Talent Grant is only given out to undergraduate students studying the sciences.
Complete grant applications as soon as possible once you find them. Competition for grants is fierce, and the grant money available is limited. Take the time to maximize your chances of getting a grant by providing the best application possible, but remember that the volume of applications makes a difference when it comes to successfully getting grants and scholarships.
