Adults who did not complete high school but who wish to show that they have high-school equivalent knowledge and skills take the GED test. Passing the GED is equivalent to a high-school diploma, often enabling holders of a GED credential to apply to colleges and get better jobs.
According to the official website for GED Testing, no states offer the GED to be taken online.
It would be impossible to accurately determine who was taking the GED test if it was offered online. Therefore, all states require that the GED test be taken in person at official, approved test centers.
The GED can only be taken in person at official testing centers. These can be found at Acenet.edu (see Resources).
The cost of taking the GED test varies from state to state. Some states offer the GED for free, and others charge fees to cover costs. Inquire at your local, official testing center for the most accurate information.
