Failed an AWS Exam? Here's the Real Retake Policy

Failing an AWS exam isn't rare, and it isn't the end of the attempt — but the retake rules are specific, and getting them wrong (either by assuming you can resit immediately, or by assuming there's some kind of free second attempt) leads to wasted money or a wasted two weeks. Here's exactly what AWS's own policy says, pulled directly from its After Testing page.

The waiting period is fixed, and it's not negotiable

If you fail, you must wait 14 calendar days before you're eligible to sit that exam again. That's calendar days, not business days, and it applies from the date of the failed attempt — you can't book a retake for day 10 and expect it to go through. AWS's testing system enforces this automatically; if you try to register before the 14 days are up, the booking simply won't let you select a date inside that window.

There's no limit on how many times you can retake a failed exam. You can, in principle, sit SAA-C03 five times if you keep failing — the only real cost is time and the exam fee each attempt.

Every attempt costs full price — there's no retake discount

This is the part people are most often wrong about: there is no reduced-price retake voucher. AWS's official pricing page states plainly that exam prices are "valid for one exam attempt" — each sitting, pass or fail, is charged at full price:

Level	Price (USD)
Foundational	$100
Associate	$150
Professional	$300
Specialty	$300

These are the published US-dollar figures; AWS notes prices are "updated at least annually in May to reflect updated foreign exchange rates" and billed in your local currency at the rate in effect when you register, so the exact amount charged on an Australian card will vary slightly through the year rather than sitting at one fixed AUD number.

The practical implication: a failed Associate-level attempt followed by a retake is $300 USD total across two sittings, not a discounted second try. That's a real reason to use the mandatory 14 days properly rather than just booking the next available slot and hoping.

What to actually do with the 14 days

AWS's exams use a compensatory scoring model — your scaled score (100–1,000, with the pass mark depending on the exam) reflects overall performance, not a per-domain pass/fail. Your score report shows a classification of performance by section, but AWS is explicit that this is general guidance, not a precise diagnostic. Treat it as a starting point, not gospel: it tells you roughly where you were weakest, not exactly which questions you missed.

With that in mind, the 14 days are best spent on:

Rereading the score report's domain breakdown carefully, and weighting your remaining study time toward whichever domain reads weakest — rather than restudying everything evenly, which wastes time on material you already know.
Running fresh scenario-based practice questions in your weak domain specifically, not just rereading notes. If the exam is testing judgment on which architecture fits a described situation, more reading without more practice questions won't close that gap.
Being honest about whether it was a knowledge gap or a timing problem. AWS's associate-level exams run 130 minutes for 65 questions — if you were rushing the final stretch, the fix might be exam-technique practice under real time pressure, not more content review.
Not re-booking immediately out of frustration. Two full weeks is enough time to make a real difference if you use it deliberately; booking for day 15 with no additional prep just repeats the same result at another $150–300.

If you've already passed, a different rule applies

This retake policy only covers failed attempts. Once you've passed an exam, AWS won't let you sit that same exam version again for two years — that's a separate rule from the standard three-year recertification cycle, and it exists mainly to stop candidates from resitting a passed exam purely to inch a marginal score higher. If AWS retires that exam code and replaces it with a new version in the meantime, you'd become eligible for the new version instead.

Reschedules and cancellations, while you're at it

Two related policies worth knowing before you book a retake: each exam appointment can be rescheduled up to twice before you need to cancel and start over, and cancelling more than 24 hours before your scheduled time gets you a full refund of the fee — inside that 24-hour window, the fee is forfeited. If your first attempt is coming up and you're not confident, moving the date is free up to twice; not showing up at all isn't.

If you're rebuilding your study plan for a retake, our domain-weighted approach to planning study time applies just as much to a second attempt as a first — arguably more, since you now have a real score report telling you exactly where the weighting should shift. And if the exam that failed you was your first AWS certification altogether, it's worth revisiting whether it was even the right starting point before you spend another $100–300 on the same one.
