DVA-C02 vs DVA-C03: Key Changes in the AWS Developer Associate Exam

AWS is updating the AWS Certified Developer - Associate certification exam. The current DVA-C02 will be replaced by DVA-C03, with registration for the new exam opening on October 27, 2026. The final day to take DVA-C02 is November 30, 2026, and DVA-C03 exam delivery begins on December 1, 2026.

For candidates preparing for AWS Certified Developer - Associate, the biggest question is simple: Should you finish DVA-C02 before it retires, or prepare for DVA-C03 instead?

DVA-C03 keeps the core AWS developer skills covered by the current certification but updates the exam for modern development workflows. Important additions include AI-assisted development, security for AI services, container development, Amazon Bedrock, Amazon Q, Kiro, and greater emphasis on troubleshooting and optimization.

DVA-C02 to DVA-C03: Important Dates

Candidates planning their certification should remember these three dates:

Candidates who are already well prepared still have time to complete DVA-C02. Those who are only beginning their preparation may find DVA-C03 a better long-term target.

DVA-C02 vs DVA-C03: Quick Comparison

Although both exams lead to the same AWS Certified Developer - Associate certification, there are important differences in what candidates need to study.

The exam format is therefore largely unchanged. The main difference is the knowledge and developer workflows being tested.

How Are the Exam Domains Changing?

DVA-C03 continues to use four major exam domains, but their weighting changes.

The most noticeable change is Troubleshooting and Optimization, which increases from 18% to 22%.

Domain 3 also evolves from Deployment to Testing and Deployment, reflecting greater attention to application testing as part of the development lifecycle.

For DVA-C03 candidates, troubleshooting, observability, application performance, testing, and optimization deserve more attention than they did under DVA-C02.

What Is New in DVA-C03?

The biggest update is the integration of AI-assisted development into the AWS developer role.

Candidates may encounter scenarios involving AI tools for:

● Code generation and code review

● Automated testing

● CI/CD assistance

● Troubleshooting recommendations

● Application optimization

● Security analysis

AWS is treating AI-assisted development as a modern developer competency rather than a separate specialist skill.

DVA-C03 also adds greater emphasis on securing applications that interact with AI services. Candidates should understand concepts such as access control, private connectivity, data protection, content filtering, prompt injection protection, agent authorization, session isolation, and human approval workflows.

New AWS Technologies to Know for DVA-C03

Several newer AWS services and tools enter or receive greater emphasis in the updated exam.

Candidates do not need to become AI or machine learning specialists. The focus remains on how AWS developers use, integrate, deploy, and secure these technologies.

AWS specifically identifies areas such as prompt engineering, RAG architecture design, AI model selection, Amazon SageMaker AI, and AI governance framework design as outside the DVA-C03 scope.

Is Your DVA-C02 Preparation Still Useful?

Yes. Candidates already studying DVA-C02 do not need to restart from the beginning.

Most foundational knowledge continues into DVA-C03.

A candidate moving from DVA-C02 to DVA-C03 should therefore think in terms of:

Keep your existing AWS foundation + add AI + strengthen containers + spend more time on troubleshooting.

DVA-C02 or DVA-C03: Which Exam Should You Take?

Your preparation progress matters more than simply choosing the newer exam.

Take DVA-C02 if you are already prepared

If you have completed most of your preparation and can confidently take the exam before November 30, there is little benefit in switching simply because DVA-C03 is newer.

Passing DVA-C02 still earns the AWS Certified Developer - Associate certification, and AWS confirms that the credential remains valid for its normal validity period.

Choose DVA-C03 if you are just starting

If you are starting from the beginning or do not expect to be ready before November 30, preparing for DVA-C03 makes more sense.

You will have more preparation time and your study will align with AWS's updated expectations for developers working with AI-assisted tools, containers, testing, and modern cloud application workflows.

How Should You Prepare if You Switch to DVA-C03?

Candidates who switch from DVA-C02 should not discard their existing study plan.

Continue learning core AWS development topics, then add four areas:

● AI-assisted development: Understand how AI tools assist with coding, testing, review, debugging, and optimization.

● AI security: Learn how to protect data, control access, secure AI interactions, and prevent unsafe application behavior.

● Containers: Build familiarity with ECR, ECS, EKS, and Fargate.

● Troubleshooting and optimization: Spend more time interpreting logs, identifying application failures, investigating performance issues, and selecting appropriate solutions.

AWS plans to make the complete DVA-C03 exam guide available when registration opens on October 27, 2026. Candidates targeting the new exam should use that guide as their final preparation checklist.

Is DVA-C03 Harder Than DVA-C02?

Not necessarily.

DVA-C03 covers a broader range of modern developer workflows, particularly around AI and containers, but the exam format remains the same and much of the core AWS development knowledge carries over.

It is more accurate to describe DVA-C03 as more current and broader in scope, rather than automatically more difficult.

Candidates already familiar with Amazon Bedrock, AI development tools, containers, and modern CI/CD workflows may actually find the new content relatively natural.

DVA-C02 and DVA-C03 FAQs

When does DVA-C03 registration open?

DVA-C03 registration opens on October 27, 2026.

What is the last day to take DVA-C02?

The final day to take DVA-C02 is November 30, 2026.

When can candidates start taking DVA-C03?

Does DVA-C03 replace DVA-C02?

Yes. DVA-C03 becomes the new AWS Certified Developer - Associate exam after DVA-C02 retires.

Do DVA-C02 and DVA-C03 give different certifications?

No. Both exams lead to the same AWS Certified Developer - Associate certification.

Do I need to take DVA-C03 if I already pass DVA-C02?

No. Passing DVA-C02 earns the certification, and your credential remains valid through its normal validity period.

What is the biggest change in DVA-C03?

The biggest changes are the addition of AI-assisted development, AI service security, expanded container coverage, and greater emphasis on troubleshooting and optimization.

Should beginners choose DVA-C02 or DVA-C03?

Candidates just starting preparation and unlikely to take the exam before November 30 should generally target DVA-C03.

Final Recommendation for AWS Developer Associate Candidates

The move from DVA-C02 to DVA-C03 is an important update, but it does not make existing DVA-C02 preparation obsolete.

If you are already close to exam readiness, finishing DVA-C02 before November 30, 2026 is still a sensible choice. You earn the same AWS Certified Developer - Associate credential without having to expand your preparation into the new DVA-C03 topics.

If you are just beginning, however, DVA-C03 is the better long-term target. It reflects how AWS developers increasingly work with AI-assisted tools, containers, automated testing, security, and modern cloud-native development workflows.

Candidates who are currently halfway through DVA-C02 preparation should continue studying the shared core topics and review the complete DVA-C03 exam guide when it becomes available on October 27 before making the final decision.
