There is a huge array of scholarships available to students. Scholarships may be available from UMass Amherst itself, your state, town, organizations at which you volunteer, and many other sources. You just have to seek them out.
All undergraduate students who have filed a Free Application for Federal Student Aid (FAFSA) form will be considered for numerous endowed and corporate-sponsored scholarships. Financial need may not be the only consideration for individual scholarships—grades, class standing, academic major, residency, and other factors may also be taken into account.
