AZ 305 renewal applies because the Microsoft Certified: Azure Solutions Architect Expert certification this exam feeds into is valid for one year. Microsoft offers a free, unproctored, open-book online renewal assessment through Microsoft Learn during a six-month window before your certification expires; passing it extends your validity one year from the expiration date.
Does AZ-305 expire?
Exam AZ-305: Designing Microsoft Azure Infrastructure Solutions is one of two exams that lead to the Microsoft Certified: Azure Solutions Architect Expert certification. That certification is valid for one year from the date you earn it. AZ-305 itself has no retirement date; Microsoft's exam page states "Retirement date: none," meaning the exam is expected to remain active, separate from the one-year validity clock that applies to the certification you earn from passing it.

| Certification validity | One year from the date earned |
| AZ-305 exam status | Active; retirement date: none |
| Renewal method | Free online renewal assessment via Microsoft Learn |
| Renewal window | A six-month window before expiration |
| Effect of passing renewal | Validity extends one year from the expiration date |
How AZ 305 renewal works
Microsoft's renewal process for this certification is free, unproctored, and open-book, taken online through Microsoft Learn. You become eligible during a six-month window before your certification's expiration date, not any time earlier. If you pass the renewal assessment, your certification's validity extends one year from the expiration date, not from the day you happened to complete the renewal, so completing it early within that window does not shorten or lengthen your new validity period.
This renewal path applies to the certification level, not to the individual AZ-305 exam. Since AZ-305 has no retirement date on its own exam page, the renewal cycle you need to track is your certification's one-year validity, not any separate date tied to the exam itself.
What to do before your renewal window opens
Keep an eye on your Microsoft Learn profile for the date your certification is due to expire, since that date determines when your six-month renewal window opens. If you have not kept up with Azure service changes since you passed AZ-305, treat the renewal assessment as a real review, not a formality: revisit the AZ-305 exam objectives page for the domain weighting your renewal will likely still reflect, and consider a run through the AZ-305 practice test if a particular domain feels rusty.
If you miss the renewal window
Microsoft's AZ-305 exam page does not state what happens if you let the renewal window pass without completing the assessment, so this page will not guess at a fallback policy. If your window has closed, check your Microsoft Learn certification dashboard directly, or consult Microsoft's general renewal policy page for the current rules rather than relying on assumptions.
Why the exam and the certification have separate clocks
It helps to keep two different timelines straight. AZ-305 as an exam has no retirement date, so Microsoft is not signaling any plan to replace or withdraw it. The certification you earn by passing AZ-305 and its companion exam, on the other hand, runs on its own one-year clock that starts the day you pass, independent of whatever Microsoft eventually does with the exam itself. A candidate who passes AZ-305 today and lets their certification lapse two years from now without renewing would still find the same active AZ-305 exam available if they needed to requalify from scratch, since the exam's status and the certification's validity are tracked separately.
This distinction matters most when you are deciding whether to renew or requalify. Renewal, through the free online assessment, is the lower-effort path and is available during your six-month window. Requalifying by passing AZ-305 again would only become relevant if you let your certification lapse entirely and the standard renewal path is no longer available to you, which is a scenario this page will not speculate about beyond noting that Microsoft's general renewal policy page is the source to check if you find yourself in that position.
