Visit the American Council on Education (ACE) website to find your state's agency responsible for administering the GED. The ACE is the organization that gives the GED exam. Typically, you'll find out about your state's regulations from the State Department of Education, though it may be different in some places. The link in the resources section will help you find this.
Print out the application for requesting your GED test results. You'll find this on the state's website.
Mail the completed form to the state. Follow the website's instructions on where to send your request. Include a check for the payment, if required.
