The General Educational Development (GED) Diploma is a high school equivalency certificate awarded upon successful completion of a test. The GED measures academic skills in five areas: writing, social studies, science, interpreting literature and the arts, and mathematics.

The Center for Adult Learning & Education Credentials , a division of the American Council on Education, has overseen the GED since 1942. According to the Center, about 95 percent of American colleges, universities and employers consider a GED diploma equivalent to a high school diploma. The average age of GED test takers is just over 24.

There are GED testing centers around the world. You can find a test center in the US or Canada by browsing their regional sites, or call the 24-hour toll-free GED hotline at (800) 626-9433. The GED test is offered internationally through Sylvan Technology Centers, and a list of international test centers is available in pdf format. The GED is available in Spanish and French . Accommodations for individuals with disabilities can be made.
