Microsoft's Azure Developer Associate certification, taken through exam AZ-204, retired on 31 July 2026. In Microsoft's own words: "This certification, related exam, and renewal assessments will retire on July 31, 2026. You will no longer be able to earn or renew this certification after this date." Since then, Microsoft Learn has listed a new developer associate certification built on exam AI-200. Here is what is confirmed, how the two compare, and what to do next.

What is confirmed

Two things are certain, straight from Microsoft's certification page. The retirement date was 31 July 2026, and you can no longer earn or renew the credential. The exam itself was proctored, gave you 100 minutes to complete it, and could include interactive components.

AI-200: the nearest new exam

Microsoft's retired AZ-204 page does not name a successor, but Microsoft Learn now lists a new developer associate certification: Microsoft Certified: Azure AI Cloud Developer Associate, earned by passing exam AI-200. It is the closest match to AZ-204, though not a like-for-like swap.

The overlap is real. AZ-204 assessed Azure compute, storage, security, monitoring, and connecting to Azure and third-party services. AI-200 assesses:

  • Develop containerised solutions on Azure
  • Develop AI solutions by using Azure data management services
  • Connect to and consume Azure services
  • Secure, monitor and troubleshoot Azure solutions

The difference is direction. AI-200 expects you to build AI solutions on Azure, and Microsoft lists vector databases and Python among the skills a candidate should have. The exam is proctored and lasts 120 minutes. Read the AI-200 study guide on Microsoft Learn before you book, as outlines change.

What happens to your certification if you already hold it

If you earned the Azure Developer Associate before it retired, you have not lost anything you cannot see coming. Microsoft's standard practice is that a certification you have already achieved stays on your transcript after the exam retires, marked as retired, rather than disappearing. It stops being renewable, and over time employers will weigh it as a credential from a specific era, but it remains a real, verifiable achievement on your record. Retirement affects your ability to earn or renew, not the fact that you passed.

If you never took it

You can no longer sit AZ-204, so plan around the skills and the role rather than the old exam.

Think about the knock-on effects and the path forward:

  • Check any certification that listed AZ-204 as a prerequisite. Some advanced Microsoft credentials accepted AZ-204 as an entry route. With the exam retired, confirm the current prerequisites on Microsoft Learn before you plan a pathway around it, and note that the Azure Administrator associate route may now be the cleaner prerequisite.
  • Target the role, then the credential. Azure developer skills are not going anywhere, but the badge that best evidences them is shifting. Look at where Microsoft's newer developer credentials sit, starting with AI-200, and pick the one that matches the work you actually do.
  • Keep the skills current regardless of the badge. The underlying competencies, building and deploying solutions on Azure, are exactly what the newer credentials still test. Time spent on the skills is not wasted just because one exam retired.

Practise for whatever comes next

Retirements like this are a reminder that the exam is a checkpoint, not the goal. The skills carry across whatever credential you pivot to, and the way you prove you have them is the same: perform under realistic, timed conditions. Whether you are lining up AI-200 or another Azure credential, full timed mocks that mirror the real format, proctored, time-boxed, with interactive-style questions, tell you whether you are ready far better than untimed revision. CandidatesPrep's simulator runs timed, scored practice exams so you can rehearse the conditions as well as the content, and trainers moving cohorts onto newer Azure credentials can track readiness across a whole group.

The bottom line

AZ-204 retired on 31 July 2026. If you hold the certification, it stays on your record as a retired credential. If you do not, AI-200 is the nearest new developer exam, but choose your next step by the role you are aiming for and check the current outline on Microsoft Learn. The Azure developer path has been rebuilt around AI, not removed, and your skills still count.
