If you did not receive a high school diploma, you can take the General Education Development (GED) exam and earn a high school equivalency certificate. The GED is administered in each state. Depending on your location, you can choose from a variety of GED testing centers in your area. Though some testing centers allow you to pre-register for the exam online, certain testing centers require you to apply for the exam in person.

Go to the American Council on Education's website (See References), which is the official site for the GED Testing Service. The ACE aids you in locating a GED testing center and provides you with sample test questions from the exam, as well as preparation techniques.

Click the "Locate Testing Center" link and enter your ZIP code to search for a GED testing center in your area. Many GED exams are administered at community colleges, vocational schools and learning centers. If you are a resident of South Carolina, visit the South Carolina State Department of Education's website to locate GED testing centers.

Contact your preferred testing center and confirm the testing center's exact location and hours of operation. Depending on your schedule, you might be able to find a testing center that administers the GED exam in the evenings or weekends.

Register for the GED. Depending on the testing center you contact, you might have the option to register online or in person. If you choose to register in person, bring a photo ID that displays your current address, your Social Security card and form of payment to cover the registration fee. Depending on the testing center, the registration fee varies.
