AZ-900 Renewal and Retakes Explained

The short version

The Microsoft Certified: Azure Fundamentals credential does not expire, so there is nothing to renew. If you fail the exam, you can retake it after 24 hours, then you wait 14 days between later attempts, with a limit of five attempts in 12 months. The details below come from Microsoft Learn pages checked on October 22, 2026.

Does the AZ-900 credential expire?

No. Microsoft’s renewal page says that fundamentals certifications do not expire, and its renewal FAQ repeats it: renewal does not apply to fundamentals certifications. Once you pass AZ-900, the credential stays on your Microsoft Learn profile and you never take a renewal assessment for it.

That is different from role-based credentials. Microsoft says its associate, expert, and specialty certifications expire after one year unless you pass a free online renewal assessment. The Azure Administrator Associate page, for example, lists a renewal frequency of 12 months. So the rule you read about “yearly renewal” belongs to the next level up, not to AZ-900.

Two practical points follow from this:

You do not need a calendar reminder for AZ-900.
You cannot retake AZ-900 to “refresh” the date. Microsoft says you cannot retake an exam you have already passed unless your certification has expired, and fundamentals certifications do not expire.

How the renewal process works for other credentials

You will not use this for AZ-900, but it helps to know how Microsoft handles the credentials that do expire, in case you move on to one.

The renewal assessment opens six months before the expiration date, on Microsoft Learn.
It is free, online, unproctored, and open book.
Microsoft says it takes about 45 minutes and focuses on recent updates.
When you pass, the certification is extended by one year from its expiration date.
If you let it lapse, you must earn the certification again by passing the required exam or exams.

Retake rules for AZ-900

AZ-900 follows Microsoft’s retake policy for role-based, specialty, and fundamentals exams.

First failure: you wait 24 hours before the second attempt.
Later failures: you wait 14 days between every further attempt, up to five attempts in total.
Annual limit: you cannot take the same exam more than five times within 12 months of your first attempt. If you fail five times, you can try again 12 months after the date of your first attempt.
Fees: you pay for each retake where a fee applies. The price depends on the country or region, so check it when you book.
Passed exams: you cannot retake an exam you passed unless the certification has expired.

The only waiver

Microsoft can waive a waiting period only if you had an internet or equipment failure during the exam and a Pearson VUE case was created. You must send the case number to Microsoft’s support team. Nothing else qualifies, including nerves, a bad night’s sleep, or a feeling that the questions were unfair.

A timeline example

Imagine you book AZ-900 for a Monday morning and do not pass.

When	What you can do
Monday	First attempt, not passed
Tuesday, 24 hours later	Earliest second attempt
14 days after the second attempt	Earliest third attempt, if the second also failed
14 days after each later attempt	Fourth and fifth attempts

Count carefully: the 14 days run between attempts, not from your first try. In practice, most people do not need the fourth attempt, and the five-attempt cap is a ceiling, not a plan.

What to do with a failed attempt

Microsoft gives you a score report with your overall score and a bar chart per skill area. It does not show which questions you missed, and Microsoft says you cannot add the bars to work out a percentage. Use the chart to find the weakest domain, then study that domain before the retake. The domains explained page shows what each area covers. Waiting 24 hours after a first failure is rarely enough time to fix a real gap, so most people benefit from using the longer gap if they have it.

What happens if the exam changes or retires

Microsoft updates the English version of an exam first. Localized versions follow about eight weeks later. The AZ-900 study guide shows skills measured as of July 20, 2026, with minor changes in three sub-areas. The exam page we checked shows no retirement notice.

If Microsoft ever does retire a certification, its renewal FAQ explains the general approach: alerts appear on Microsoft Learn, and exams or certifications can be retired when they lose relevance, when a product is deprecated, or when the program merges exams. If you passed before a retirement, check your Learn profile and the certification page for what applies to you, because Microsoft Learn is the authority.
