The AZ-203 Developing Solutions for Microsoft Azure certification exam tests and validates your expertise as an Azure Developer. This exam tests your expertise across all phases of the Microsoft Azure development process; from solution design, to development and deployment, to testing and maintenance.
NOTE: The AZ-204 Developing Solutions for Microsoft Azure certification exam was announced by Microsoft, in early 2020, to be replacing the AZ-203 exam. The AZ-204 exam was made available in February 2020, with a 90-day phased rollout where both AZ-203 and AZ-204 exams will be available. After this phased roll-out, the AZ-203 exam will be retired on or around August 31, 2020 leaving only the AZ-204 exam to be available for earning the Microsoft Certified: Azure Developer Associate certification.
The AZ-203 exam was originally rolled out in 2018 as a replacement for the AZ-200 + AZ-201 or AZ-202 exams for earning the Microsoft Certified: Azure Developer Associate certification. This was a move to simplify the process to earning this certifications based on feedback from those who have taken the exams while they were in a “Beta” state. Thanks to those early certification achievers, we all have a simplified process to follow now.

Microsoft Certified: Azure Developer Associate
Once a candidate passes the AZ-203 Developing Solutions for Microsoft Azure certification exam they will earn the Microsoft Certified: Azure Developer Associate certification.
The Microsoft Certified: Azure Developer Associate is part of a job-role based restructuring of the Microsoft certifications. This particular certification is geared towards candidates who are Azure Developers in their normal job in designing and building cloud-based software solutions utilizing the Microsoft Azure cloud platform.
Take Azure Fundamentals AZ-900 Exam First
The AZ-203 Developing Solutions for Microsoft Azure certification exam does not have any prerequisites to take. However, if candidates are new to Microsoft Azure development, then they may want to take the AZ-900 Microsoft Azure Fundamentals certification exam first. This will validate their knowledge and understanding of the fundamentals of Microsoft Azure.
If candidates are new to the cloud, or to Microsoft Azure, then the AZ-900 Azure Fundamentals could be a good place to start.
What’s Next? The Microsoft Certified: Azure DevOps Engineer Expert!
Once a candidate has already earned the Microsoft Certified: Azure Developer Associate certification they can take another exam to upgrade to the Microsoft Certified: Azure DevOps Engineer Expert certification. The DevOps Engineer Expert certification is earned on top of the Azure Developer Associate by taking and passing the additional AZ-400 Microsoft Azure DevOps Solutions certification exam.
Transition from AZ-200 + AZ-201 Exams to Single AZ-203 Exam
In early stages of the Microsoft Certified: Azure Developer Associate certification, Microsoft Learning received a lot of feedback about the new “Beta” exams. Based on this feedback they decided to combine the AZ-200 and AZ-201 certification exams into a single AZ-203 Developing Solutions for Microsoft Azure certification exam.
The combined AZ-203 Developing Solutions for Microsoft Azure certification exam is not merely a merging of the full AZ-200 and AZ-201 certification exams. The AZ-203 exam pulls in approximately 70% of its objectives from the AZ-200 exam, and approximately 30% of its objectives from the AZ-201 exam.
As a result of the transition, the AZ-200 and AZ-201 certification exams are now retired (as of December 27, 2018), and are no longer able to be scheduled or taken. Additionally, the Transition exam AZ-202 is also retired as the single AZ-203 exam is the singular path to earning the Microsoft Certified: Azure Developer Associate certification.
Anyone who has previously taken the AZ-200, AZ-201, or AZ-202 exams when they were in “Beta”, will be receiving communication from Microsoft as to whether they passed sufficiently to earn the certification, or if they will need to take the new AZ-203 certification exam. For those early achievers, this may be a bit frustrating, but this change will simplify the certification process for this certification, and is a good change to be made.
