The short version
DVA-C03 has no required prerequisite exams. AWS recommends at least one year of hands-on experience building applications on AWS and comfort with at least one programming language. Cloud Practitioner is a suggestion only for people with no IT background.
What AWS says
AWS describes the exam as suited to people in IT or cloud developer roles. Its September 2026 announcement recommends at least one year of hands-on experience developing applications with AWS services. The current DVA-C02 exam guide adds general IT knowledge: proficiency in a high-level language, understanding of the application lifecycle, basic knowledge of cloud-focused applications, and experience with development tools. On the AWS side, it expects you to use service APIs, the AWS CLI, and SDKs, and to use a CI/CD pipeline to deploy.
AWS published the DVA-C03 exam guide on October 27, 2026. Check it in case its wording differs from the above.
Required versus recommended
| Required | Recommended | |
|---|---|---|
| Another AWS exam | No | Cloud Practitioner if you have no IT experience |
| Hands-on AWS | No | One year or more building applications |
| Programming | No formal proof | Fluency in a language such as Python, JavaScript, Java, C#, or Go |
| Tools | No | CLI, SDKs, Git, a CI/CD tool |
Suggested earlier certifications
AWS only names one: Cloud Practitioner, for candidates with no IT experience. Anything else is a matter of taste. Some people build confidence by taking a foundational exam first, but you can go straight to DVA-C03.

What to learn first if you are new to AWS

- Learn the shared basics: regions, IAM users and roles, and the console and CLI.
- Build a tiny serverless app: an API Gateway endpoint, a Lambda function, and a DynamoDB table.
- Add a queue or an event rule so one part triggers another.
- Deploy it with SAM, then break it and read the logs.
AWS Skill Builder offers an exam prep plan for Developer – Associate. It is listed for DVA-C02 at the time of writing, and most of the foundation applies to DVA-C03 too.
Accessibility and language
AWS lists six exam languages: English, Japanese, Korean, Portuguese (Brazil), Simplified Chinese, and Spanish (Latin America). If you take the exam in English and it is not your first language, you can request a 30-minute extension through your AWS Certification account before you register.
