How Old Do You Have to Be to Get a GED? (2026 State-by-State Guide)

In most US states you must be at least 16 with an age waiver or 18 without restrictions to take the GED. A few states require 17 or 18 as a minimum. Underage candidates typically need parental consent, official withdrawal from high school, and sometimes district approval. There is no maximum age — adults of any age can take the GED at any time.
