Question: how long are asvab scores good for prior service?
Answer: Minimum Waiting Times. ASVAB tests are valid for two years, as long as you are not in the military. In most cases, once you join the military, your ASVAB scores remain valid as long as you are in. In other words, except in a few cases, you can use your enlistment ASVAB scores to qualify for retraining years later.
