How many high school credits will transfer from a GED?

There's no set number of high school credits a GED will transfer for. It entirely depends on the policies of the individual college or university, or even the specific high school if you're pursuing further high school education. Some institutions may grant a certain number of general credits, while others may evaluate the GED in conjunction with other factors. You'll need to contact the admissions office of the specific institution you're applying to.
