PL-400

Both are open for a window. PL-400 registration closes October 16, 2026, and anyone registered on or before that date can schedule and sit the exam through October 30, 2026 at 11:59 PM Central Standard Time. AB-400, Extending Microsoft Power Platform Solutions with Code and AI, is available beginning October 16, 2026 and is listed as the required exam for the Developer Associate certification.

The exam page states a passing score of 700. Scores are reported on a scaled basis rather than as a raw percentage of correct answers, so you cannot map 700 directly to a count of questions. Microsoft's exam scoring guidance is linked from the exam page if you want the details.

Microsoft does not publish a question count or time limit on the PL-400 exam page, so do not plan around a fixed number. Confirm the appointment length when you schedule. For pacing practice, use the exam sandbox demo and the practice assessment that the page links to.

Retake rules are governed by Microsoft's exam policies and FAQs, which the exam page links to; the PL-400 page itself does not list a retake policy. If you are sitting PL-400, remember the hard stop: the exam retires October 30, 2026, so leave yourself room to retake before that date.

It is a developer-level exam, not a maker one. Extend the platform alone is 35-40% of the measured skills, and the audience profile assumes development experience with JavaScript, TypeScript, C#, HTML, RESTful web APIs, and Azure. Candidates without a coding background typically find the extension and integration objectives the steepest.

Start with the heaviest weighting and work down: extend the platform (35-40%), then configure Microsoft Dataverse (15-20%), then create a technical design, create and configure Power Apps, and extend the user experience (10-15% each), finishing with develop integrations (5-10%). Integrating the smallest domain last works well because it builds on the extension skills.

Treating the exam as pure low-code. The skills outline assumes you understand Power Platform boundaries and constraints, authentication and security, and application lifecycle management practices. Weak spots also show up around custom code extension points, web APIs, and Azure integration, where hands-on building beats reading.

Yes. Microsoft points candidates to a practice assessment and to an exam sandbox where you can try the testing experience before exam day. The study guide linked from the exam page lists the measured skills and recent changes, which is the best checklist for deciding what to review next.
