Earn your GED. Accredited U.S. colleges and universities require students to have a GED if they have not graduated from high school. A GED is a good idea in general because it opens other doors, too, like better jobs. To earn your GED, you will need to pass five tests. Do not be intimidated by the tests. People pass them all the time and there are many resources available to help you be successful.
Enroll in a community college program. Community colleges are more lenient in their admissions requirements and offer attractive transfer options to four year colleges. Some community colleges offer programs designed as bridge programs that help students obtain their GED. Call your local community college's admissions office and ask them about options that fit your situation.
Apply directly to a college or university, upon obtaining your GED. Schools generally require a minimum of a GED for admission. Colleges evaluate applicants in several areas; high school completion or GED, is just one area. To improve your chances of admission, get strong letters of reference from people who have known you well, that explain why failing to graduate high school does not predict your ability to graduate from college. Write a powerful personal statement that includes your college goals, your motivation for a college degree and a plan for making college successful, such as resources you will like tutoring, strong relationships with professors, meeting regularly with an adviser and making schoolwork a priority. Take the SAT or ACT college entrance exams. Study beforehand and do your best, retaking the test if you feel you can do better a second time. College entrance exam scores will help admissions committees gauge your academic ability when you do not have a complete high school transcript.
File the Free Application for Federal Student Aid (FAFSA). This application is used to determine your eligibility for federal income based financial aid programs. U.S. schools use the FAFSA to determine your eligibility for school based aid as well. File the FAFSA as early as possible, trying to complete it before the school's priority deadline, which is typically February 15 at most colleges and universities. Fill out a FAFSA for community colleges also, if you choose that route.
Ask about resources available to support you during your studies, once accepted. Schools want their students to be successful and often offer a plethora of programs to help you succeed. Anywhere from free tutoring, writing help, social support and programs specifically designed for students who were high school dropouts. Take advantage of the services that are available to you.
