AZ-900 renewal and retake rules
Microsoft Certified: Azure Fundamentals does not expire, so there is nothing to renew. The rules that do apply to AZ-900 are the retake limits: wait 24 hours after a first failed attempt, then 14 days between later attempts, with at most five attempts in 12 months. Microsoft publishes both rules on its Learn site, and this page walks through them as of 2026-10-09. The mechanism is the same for every Microsoft fundamentals exam; the details about the AZ-900 outline are specific to this one.
Fundamentals never expire: what that actually means
Microsoft’s renewal FAQ states: “Renewal does not apply to fundamentals certifications as they do not expire.” Associate, specialty and expert certifications are different. They expire after one year and are renewed for free by passing an unproctored, open-book assessment on Microsoft Learn in a six-month window.
Consequences for AZ-900 holders:
- There is no renewal assessment, no fee and no deadline. You do not need to look at your profile once a year.
- Microsoft’s retake policy says you cannot retake an exam you have passed unless your certification has expired. Because this one does not expire, you cannot sit AZ-900 again to refresh your date.
- Updates to the exam outline (the latest took effect on July 20, 2026 and was marked minor for compute and networking, deployment tools and monitoring) do not affect a certificate you already hold.
What Microsoft does not state is what would happen if it retired the Azure Fundamentals certification itself. The FAQ describes retirement only for renewable certifications, so no statement about fundamentals is available. Treat that as unpublished.
The retake ladder after a failed attempt
The retake policy for role-based, specialty and fundamentals exams reads as follows:
| Attempt | Rule |
|---|---|
| After the first failure | Wait 24 hours |
| Each later attempt (up to five) | Wait 14 days after the previous one |
| Limit | No more than five attempts in 12 months, counted from the first attempt |
| After five failures | Eligible again 12 months after the date of the first attempt |
| Fee | You pay again for every retake, where an exam fee applies |
A worked example: fail on 1 March, retake on 2 March, fail again, and the third attempt cannot be before 16 March. If all five attempts fail, the sixth cannot be before the following 1 March.
Because AZ-900 is a 45-minute exam with a 14-day gap, most people use the gap for one specific purpose: the score report. Microsoft states that the report gives a numeric score, pass or fail status and a bar chart per skill area, and that it does not reveal which questions were wrong. The chart cannot be converted into a number of correct answers. Use it to decide which of the three domains to revisit, starting with the largest: architecture and services at 35 to 40 percent.
When the waiting period can be waived
Microsoft grants a waiver for only one reason: an internet connectivity problem or equipment failure during the exam, with a Pearson VUE case created at the time. The request must include the Pearson VUE case number and goes to Microsoft’s certification support. Without that case, Microsoft states you do not qualify. Nervousness, a bad day or a disputed question are not grounds.
Students and educators who test through Certiport get their result on screen immediately, according to the scoring page. Both providers post results to your Learn profile within 24 hours.
Language, time and accommodations
The English exam is updated first and localised versions follow about eight weeks later. If the exam is not available in your language, the study guide says you can request an additional 30 minutes. Other accommodations, such as assistive technology or extra time for disability, need approval in advance through Pearson VUE, which Microsoft says may take up to 10 business days. Arrange this before booking, not after a failed attempt.
Keeping the credential safe
The renewal question hardly matters for AZ-900, but the account question does. Microsoft recommends registering with a personal Microsoft account because records tied to a work or school account are lost if you leave the organisation. A certificate that never expires is only useful if you can still sign in to the profile that holds it.
If you hold only fundamentals, the next credentials do expire. See what AZ-900 leads to for the associate exams, and the exam format for fees and structure. For cost planning across exams, use the certification costs overview, and for outline changes elsewhere, the exam changes page.
