We did not find a state program that pays the test fee.

At US test centers, GED Testing Service waives its fee on retakes of a failed subject (up to two discounted retakes, used within 12 months). State and test-center fees may still apply. Online retakes are not discounted.
How old do you have to be to take the GED in Missouri?
The standard minimum age to take the GED in Missouri is 17.
Rules for younger test takers: Under 17, you need an approved age waiver. You must be in a Missouri Option Program, have withdrawn from school with 16 credits, or be home-schooled under state rules with a parent's written permission. Otherwise you wait until 17.
The minimum age to test online is 16.
Nationally, GED Testing Service says test takers must be at least 16 and not enrolled in an accredited high school. Each state adds its own rules.
If you are under 18 and test online, a parent or guardian must be with you at check-in (GED Testing Service policy).
Do you have to live in Missouri to take the GED?
Yes. You need to live in Missouri to take the GED there.
You need a Missouri mailing address. Prove residency on test day with a government-issued photo ID.
Where a state requires residency, GED Testing Service asks you to self-certify that you live there before you schedule. The state may check further.
Can you take the GED online in Missouri?
Yes. Online testing from home is available in Missouri for $36 per subject.
Details: Online testing is available. You need a green GED Ready score before you schedule.
Some students who test at home say working math on an on-screen whiteboard feels slow, so some choose a test center for Math. Practice your scratch work on screen if you plan to test online.
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.
What are the GED retake rules in Missouri?
In Missouri: In person, no wait after your first failed attempt; after three attempts, wait 60 days. 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 Missouri require?
Missouri 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.
You can combine GED and HiSET subject scores. Adult Education and Literacy programs offer free preparation classes.
Bring a non-expired, government-issued photo ID on test day (GED.com).
What is the GED credential called in Missouri?
When you pass, Missouri issues the Certificate of High School Equivalence.
To pass, you need a score of 145 or higher on each of the four subjects: Math, Reasoning Through Language Arts, Science and Social Studies (GED.com).
