Check with your English teacher and your high school counselor and ask them to help you find scholarships that are pertinent to an English major. Often, teachers belong to organizations that support their vocation, and he may be able to nominate you for one or more scholarships from English teaching organizations. Likewise, your school counselor is there to help match students with scholarships and grants for their chosen college path.
Search for business associations and societies that support your future English career. For example, if you're considering a career or education in journalism, the Society of Professional Journalists (SPJ) supports several scholarships for future journalists. There are similar organizations for writers, editors, technical writers, English teachers, and other careers that pertain to English degrees.
Contact the universities that you plan to apply to. Typically, a university will have scholarship opportunities both in their financial department and their English department, and you can check your potential eligibility for the scholarships available.
Investigate your state's Department of Education website as well as the Federal Student Aid website for more scholarship applications. For example, the Federal Student Aid site lists over 90 scholarship opportunities for an English major.
Consider signing up for several scholarship search engines. While many of these may be too generalized, others such as Sallie Mae's Scholarship Search will allow you to enter a specific profile that will include listing your major, school or schools of choice, and your planned future career in English. The results from the search will give you a list of scholarships tailored to your needs.
