Determine your availability. If you are planning on returning to school full time, availability isn't an issue so much as how you are going to fund your full time student status. However, if you are going to work full time and attend school part time, coordinating your schedule becomes a bigger deal. If you are attending school on campus and working during regular business hours, inform your employer of your intent to return to school. Ask for a more flexible schedule where you can attend classes during the week and make up hours in the evenings or on weekends.
Write down schools in your area that have a MFA in graphic design Program. If you are unsure of who has one, visit each school's website and see what Master's programs they offer. If you are willing to move to a new school, use a college search engine or a Master's program search site to pull up schools in the potential region you would like to move to. If you are not willing to move and have no schools that offer an MFA in your area, consider getting your MFA in graphic design from an accredited online University.
Organize your credentials. Once you have narrowed down your list of schools, review the requirements for admission to the MFA program. If you are required to take the GRE and you have not taken it, arrange a time to take the test. Most MFA programs require a resume, transcript from your undergraduate degree, and a portfolio for admission. Assembling a portfolio is merely to assure the institution you are applying to that you are creative and invested in Graphic Design. If you have never done any type of graphic design before, use your spare time to familiarize yourself with the basics and build a portfolio of artwork, whether it be digital art, painting, drawing, or other medium.
Apply for admission. Send your transcript from your undergraduate degree to your potential institutions. Be aware that the application process costs money. You need to pay application fees as well as transcript fees. You will probably require references, so before you begin the application process ask your references for letters and give them the address to the institutions you are applying to. Apply to all potential schools that you are interested in, especially if you are unsure of your chances of admission. The more schools you apply to, the better your chances at getting an MFA in graphic design.
Get in. The preparation is a large part, but the only part that matters is if you get accepted to a school if you are trying to get an MFA. If your first string of applications comes up with no one admitting you, try a second round of applications to institutions. The bottom line is that you need to keep trying to get your foot in the door. Once you've been accepted into a school, the real work begins.
Work hard and finish your degree. Keep the GPA that the school requires you to maintain to complete your degree. Stay focused on your school work and apply yourself to get you through school.
