Complete the FAFSA, the free application for federal student aid (fafsa.ed.gov). You can still receive a TEACH grant if your completed FAFSA does not show financial need, but you are required to file the FAFSA before you can be considered for a TEACH grant.
Enroll in classes. Alabama high school students must be enrolled in undergrad classes at an Alabama university before they can get a TEACH grant. Because enrollment dates for the fall semester fall after your high school graduation date you will need to enroll in summer classes if you want to receive a TEACH grant while you are still in high school.
Contact the financial aid office at the Alabama college you are attending to request a TEACH grant. The financial aid office provides you with the paperwork you need to sign to receive a TEACH grant. Once your grant is awarded to you, it is sent to your school and disbursed to you.
