How Microsoft's one-year expiry and free online renewal assessments work — windows, retakes, which certs never expire, and what happens if you miss the date.

An Azure certification you fought through a proctored, 100-minute exam to earn can be kept alive from your sofa, for free, with a book open — but only if you act inside a six-month window. That asymmetry is the whole story of Microsoft's renewal model, and it trips people in both directions: some assume renewal must mean re-sitting the exam and put it off; others assume a "Microsoft certification" lasts three years like an AWS or CompTIA credential and let it lapse without noticing.
Short answer: Microsoft role-based and specialty certifications (associate and expert level — AZ-104, AZ-305, AZ-400, SC-200, PL-300 and the rest) expire 12 months after you earn them. You renew free of charge by passing an unproctored, open-book online assessment on Microsoft Learn, available during the final six months before your expiry date; passing extends the certification one year from its expiration date. Fundamentals certifications (AZ-900, SC-900, DP-900, AI-901-based Azure AI Fundamentals) never expire and need no renewal.
Which Microsoft certifications expire — and which don't
Microsoft splits its portfolio into two regimes:
- Never expire: fundamentals certifications. Once you hold Azure Fundamentals, Security, Compliance, and Identity Fundamentals, or Azure Data Fundamentals, they sit on your transcript permanently with nothing to maintain.
- Expire after 12 months: role-based (associate and expert) and specialty certifications. Microsoft's certification pages state this as a "Renewal Frequency" of 12 months.
Note what is absent from the Microsoft model compared with other providers: there are no continuing-education credits to log, no annual maintenance fee, and no paid recertification exam. The renewal assessment is the entire mechanism. If you are comparing maintenance models across providers, see renewal vs recertification: what is the difference — Microsoft's approach fits neither camp neatly, being a free assessment rather than a CE programme or a proctored re-exam.
How the renewal assessment works
The renewal assessment is deliberately unlike the original exam:
| Original certification exam | Renewal assessment | |
|---|---|---|
| Cost | Paid (price varies by country/region) | Free |
| Proctoring | Proctored, via Pearson VUE (test centre or online) | Unproctored |
| Where | Scheduled appointment | On demand, on Microsoft Learn |
| Materials | Closed book | Open book |
| Attempts | Paid per attempt, retake waits apply | Unlimited retakes before expiry |
| Effect of passing | Earns the certification | Extends it one year from its expiration date |
Three details in that table deserve emphasis.
It is genuinely free and genuinely open book. There is no fee and no proctor; Microsoft designed it as a knowledge refresh on what has changed in the role area, not a re-examination. Treating it with the dread of the original exam is the most common overreaction.
Retakes are unlimited — until expiry. Fail the assessment and you can simply take it again, as often as needed, at no cost, provided your certification has not yet expired. The only genuinely losable resource is time.
Passing extends from the expiration date, not the renewal date. Renewing five months early does not cost you five months. Your new expiry is one year on from the old expiry date, so there is no reason to game the timing by waiting.
The timeline: what happens when
- Day 0 — you earn the certification. The 12-month clock starts.
- Month 6 — the renewal window opens. The assessment becomes available on Microsoft Learn for the final six months of validity. Sign in with the same account that holds your certification and find the renewal option against the credential on your profile.
- Months 6–12 — take the assessment. Pass at any point in this window and the certification extends one year beyond its current expiry date. Fail, review the feedback, and retake — unlimited attempts, no charge.
- Month 12 — expiry. If you have not passed the assessment by the expiration date, the certification expires. The renewal assessment is a pre-expiry mechanism; once the date passes, the free path is gone and re-earning the credential means going back through the full paid, proctored exam. (What an expired credential means for your CV is a broader question — see what happens when a certification expires.)
The practical rule that falls out of this: take the assessment early in the window. Someone who attempts it in month seven has five months of free retakes as a safety net; someone who first opens it the week before expiry has none.
What the assessment covers, and how to prepare
Renewal assessments focus on keeping certified professionals current with how the technology has moved since they tested — which, in the Azure world, is the entire point of an annual cycle. Microsoft Learn pairs each renewal assessment with a collection of learning modules covering the updated content, and because the assessment is open book, working through those modules with them still open in another tab is a legitimate and intended approach.
A realistic pattern for a working Azure administrator renewing AZ-104: block one afternoon when the window opens, skim the renewal collection on Microsoft Learn for anything that has changed in identities, storage, compute, networking or monitoring since last year, then sit the assessment the same day while it is fresh — with months of retake headroom if it goes badly. If your daily work has drifted away from parts of the role, a broader refresher helps; the exam pages under the Microsoft exams hub include free sample questions, and a timed run through AZ-104 practice questions will show you which domains have gone rusty before you rely on them in the assessment.
Renewal edge cases worth knowing in 2026
Retired certifications cannot be renewed. Microsoft is retiring a wave of role-based certifications through 2026 — Azure Developer Associate (AZ-204) and Azure AI Engineer Associate (AI-102) are already retired, and Azure Security Engineer Associate (AZ-500) retires on 31 August 2026, after which it can be neither earned nor renewed. When a certification retires, its renewal assessment retires with it: existing holders keep the credential on their transcript, but the annual extension path ends. If one of your certifications carries a retirement notice on its Microsoft Learn page, check that page for the stated cut-off and plan a successor credential rather than counting on another renewal cycle.
Expert certifications renew independently of their prerequisites. Azure Solutions Architect Expert requires you to hold Azure Administrator Associate (AZ-104) to earn it in the first place. Each certification you hold then has its own expiry date and its own renewal assessment on your profile — holding several Azure credentials means several annual renewal dates to track. A simple system for juggling multiple deadlines across providers is covered in how to keep your certifications current.
Pricing and policy specifics live on Microsoft Learn. Exam prices vary by country and region, and renewal mechanics are defined by Microsoft's renewal page — when in doubt, the page at learn.microsoft.com on renewing your Microsoft certification is the authority, and it is where any future policy change will appear first.
Frequently asked questions
Is the Microsoft renewal assessment really free?
Yes. The online renewal assessment on Microsoft Learn carries no fee, is unproctored and open book, and allows unlimited attempts before your certification's expiry date.
Do Azure Fundamentals certifications like AZ-900 expire?
No. Fundamentals certifications never expire and have no renewal requirement. Only role-based and specialty certifications carry the 12-month cycle.
How long do other providers' certifications last by comparison?
Most major bodies (CompTIA, AWS, Cisco, PMI, ISC2, ISACA) run three-year cycles, which is why Microsoft's one-year rhythm surprises people. A cross-provider reference table lives in how long professional certifications stay valid.
Does renewing cost me anything at all?
No fee, no continuing-education credits, no maintenance charge — the cost is an hour or two of your time inside the six-month window. Missing the window is what gets expensive, since re-earning the certification means paying for the full proctored exam again.
Put the window on your calendar, not in your memory
Microsoft made renewal about as friction-free as certification maintenance gets: free, open book, unproctored, infinitely retakeable — and then attached it to a hard deadline with no grace on the far side. So the entire skill of keeping Microsoft credentials active reduces to one habit: the day you earn or renew a role-based certification, set a reminder for six months out, and sit the assessment in the first weeks of the window rather than the last. Everything else about the process is forgiving; the expiry date is not.
