ExploreAbout this exam
The Certified Backstage Associate (CBA) is a Linux Foundation certification that validates practical skill with Backstage, the open source framework for building internal developer portals and standardized developer platforms. The source page positions it around developer and engineering onboarding, cross-team collaboration, and product innovation, and frames the credential as proof that a holder can work with Backstage to build standardized developer platforms. It is aimed at a beginner experience level, so it suits developers, platform engineers, and DevOps practitioners who are starting to build or operate a Backstage-based portal rather than specialists with years of framework experience. The exam is delivered online with proctoring in multiple-choice format and runs 90 minutes. Content is weighted across four domains: Customizing Backstage carries the largest share at 32%, followed by Backstage Development Workflow at 24%, then Backstage Infrastructure and Backstage Catalog at 22% each. Those domains span local project setup and TypeScript builds, containerizing a project with Docker, configuring and deploying Backstage and understanding its client-server architecture, populating and troubleshooting the catalog including annotations and automated ingestion, and writing frontend and backend plugins with React and Material UI. To prepare, work through each domain in proportion to its weight, and get hands-on with a local Backstage instance so the catalog and plugin topics are concrete rather than theoretical.
What you'll study
About Certified Backstage Associate preparation
What does the CBA exam actually cover?
Four domains: Backstage Development Workflow (24%), Backstage Infrastructure (22%), Backstage Catalog (22%), and Customizing Backstage (32%). Topics range from local project setup, TypeScript compilation, and Docker image builds through configuration, production deployment, catalog ingestion and troubleshooting, to frontend versus backend plugins and React with Material UI.
How long is the exam and what is the format?
It is an online, proctored, multiple-choice exam with a duration of 90 minutes. Because every item is multiple choice, you are not asked to write code during the exam, but questions can still probe concrete details of configuration, catalog behavior, and plugin structure.
How much does it cost, and what does the fee include?
The exam alone is $250. That includes 12 months to schedule and take the exam, two exam attempts, and a digital badge. A bundle with a THRIVE-ONE Annual Subscription is offered at $495 if you also want access to the broader e-learning catalog.
How many attempts do I get if I fail?
The certification includes two exam attempts, and the exam details also list one retake. In practice you should plan on the possibility of a single retake, so treat the first sitting seriously rather than as a diagnostic run, and address weak domains before scheduling again.
How long is the certification valid?
The online certification is valid for 2 years. After passing, the source recommends adding the badge to LinkedIn, LFX, GitHub, and other profiles so employers and the open source community can see the credential.
What experience level is expected?
The listed experience level is beginner. The source also suggests a solid foundation in IT infrastructure, cloud computing, DevOps, and security helps, so familiarity with containers, command-line tooling, and general web development concepts is more useful preparation than deep Backstage expertise.
In what order should I study the domains?
Start with Backstage Development Workflow so you can run a project locally, since the other domains assume that baseline. Then take Infrastructure for configuration and deployment, Catalog for entity ingestion and troubleshooting, and finish with Customizing Backstage, the heaviest domain at 32%, where plugin and React knowledge matters most.
What are common ways candidates lose points?
Two traps stand out. First, under-preparing Customizing Backstage, which is 32% of the exam and covers frontend versus backend plugins and React changes. Second, skimming the catalog domain, where annotations, manually registered entity locations, automated ingestion, and ingestion troubleshooting are easy to conflate if you have never debugged a real entity.
Is there a money-back guarantee?
The certification page displays a 100% money back guarantee alongside the exam details. Review the linked policies and candidate handbook before enrolling so you understand the conditions that apply, since the guarantee terms are governed by those documents rather than by the marketing summary.
