CCDV-F is the builder's credential in Anthropic's certification program. It is written for people who ship Claude applications rather than people who use Claude at work, and the guide says so: one to five years of software engineering, six months on Claude or a comparable model, Python or TypeScript, and comfort with REST APIs and the command line.
The weighting is the thing to read first. Applications and Integration is a third of the paper on its own, at 33.1%, and Model Selection and Optimization takes another 16.8%. Claude Code is 3.1% and the whole of Eval, Testing and Debugging is 2.6%. An exam named after a developer credential spends half its items on API mechanics, application design and the cost and latency of a model choice.
Most items are a short build scenario with a constraint in it. Several options would work. One meets the constraint the scenario stated, whether that is a nightly batch job that cannot cost what realtime costs, a tool that has to be reusable across three applications, or untrusted page content that must not reach a destructive action.
The platform moves fast, which is what older material gets wrong. These tests are written against the exam guide dated July 2026 and the Claude platform as it stands, including the current model lineup, the Agent SDK, prompt caching, hooks and MCP.
