DVA-C03 Exam Guide: AWS Developer Associate

The short version

DVA-C03 is the new version of AWS’s Developer – Associate exam. It tests whether you can build, secure, deploy, and debug applications on AWS: Lambda, API Gateway, DynamoDB, messaging, IAM, KMS, CI/CD, and observability. Delivery starts December 1, 2026. AWS’s sources differ on when registration opens: the DVA-C03 exam guide, which leads, says December 1, 2026, while an AWS blog from September 2026 said October 27, 2026. AWS published the exam guide on October 27, 2026, and this guide follows it, with the September 2026 announcement and the DVA-C02 exam guide for comparison.

What the exam is

The credential is called AWS Certified Developer – Associate. AWS aims it at people in IT or cloud developer roles who build and maintain applications on AWS. It is an associate-level exam, so it is a step up from the fundamentals tier. It is also a hands-on-flavored exam. Most questions describe a small application problem and ask which service, setting, API call, or code approach fixes it.

Think of the typical question as a short bug report. A function times out, a message is processed twice, a deployment needs to shift traffic slowly, or a secret ends up in a log. You pick the answer that solves that exact problem with the least extra work.

Who it is for

AWS recommends at least one year of hands-on experience developing applications with AWS services. It also assumes you can write code in at least one high-level language and understand the application lifecycle. If you have no IT background at all, AWS suggests starting with Cloud Practitioner. The prerequisites page has a self-check.

The four domains and their weightings

The DVA-C03 exam guide lists these domains and weightings.

DomainWeighting
Development with AWS Services30%
Security26%
Testing and Deployment22%
Troubleshooting and Optimization22%

Development with AWS Services

Application code, Lambda, and data stores. Expect APIs and SDK calls, messaging and event-driven patterns, streaming data, DynamoDB, and caching.

Security

Authentication and authorization (Cognito, IAM roles), encryption with KMS, secrets handling, and a new task on securing AI services and agents.

Testing and Deployment

Packaging, infrastructure as code with AWS SAM and CloudFormation, test events, environments, and CI/CD with deployment strategies and rollbacks.

Troubleshooting and Optimization

Logs, metrics, traces, custom metrics, root cause analysis, and tuning for performance, concurrency, and cost.

What changed from DVA-C02

AWS names these changes:

  • AI-assisted development now appears across all domains, for example code generation and review, test automation, and troubleshooting suggestions.
  • A new security task covers AI security: access management for AI services, data privacy controls, content filtering and prompt-injection protection, AI agent interactions, and sensitive content in logs.
  • Container topics were added: building images with Amazon ECR and deploying with Amazon ECS, Amazon EKS, and AWS Fargate.
  • New in-scope services include Amazon Bedrock, Amazon Bedrock AgentCore, Amazon Quick, Kiro, Amazon Data Firehose, and AWS PrivateLink.
  • Several skill areas were merged, including DynamoDB, encryption, testing, observability, and optimization.
  • Prompt engineering, RAG design, AI model selection, Amazon SageMaker AI, and AI governance framework design are out of scope.

Frequently asked questions

Is DVA-C03 the same as DVA-C02?

No. It keeps the same core developer skills but adds AI-assisted development, an AI security task, container topics, and new services. The weightings also differ from DVA-C02, which AWS’s current guide lists as 32, 26, 24, and 18 percent.

How long is the certification valid?

Three years. You can recertify by passing the latest version of the exam, or by earning AWS Certified DevOps Engineer – Professional.
