Details: Online testing is open from age 16. You need a green GED Ready score within the last 60 days before you schedule.

To test online, GED.com requires:
A computer with a webcam and reliable internet.
A "green" GED Ready score (Likely to Pass) within the last 60 days, for each subject you want to test online.
A private room with a closed door, and a government-issued photo ID.
You must be in the United States while you test.

In Idaho: In person, no wait after your first failed attempt. After three attempts, wait 60 days after each attempt you do not pass. Online, you get one retake before a 60-day wait.
The national rule from GED Testing Service: at a test center, you can retake a subject you did not pass two times with no waiting period. After a third or later attempt, you wait 60 days. Online, you get one retake before a 60-day wait. State rules can be stricter, and they come first.
If you miss by a few points, you keep the subjects you passed and retake only the one you missed. Review the topics from your score report before you book again.
What else does Idaho require?
Idaho does not require GED Ready to book at a test center. You do need a green GED Ready score to test online. Taking it anyway is a good way to check that you are ready.
Bring a non-expired, government-issued photo ID on test day (GED.com).

Where can you check the official Idaho rules?
Check two places before you book: the Idaho state agency and the Idaho page on GED.com. When they disagree, ask the state agency.
GED.com names the credential the GED Transcript and High School Equivalency Certificate; the state calls it a GED credential and issues the certificate to people who passed before 2014.
