A third of the CCDV-F exam is about one domain most candidates barely study: Applications and Integration. This course follows the official Exam Guide v1.0 skill by skill, with working Python and TypeScript code, 7 exam trainers, study games and a 53-question mock exam.
You build with Claude every day, so the Claude Certified Developer – Foundations exam feels like home ground. Then the questions start: batch or realtime for a nightly job, which model tier for a support bot on a budget, where a failure starts when the JSON comes back broken, how to stop an agent from following instructions hidden in a web page. Every option sounds like something a good engineer would do. Most people prepare on agents and prompts, while API mechanics, application design and configuration carry 33.1% of the score. And a failed attempt costs you the $125 fee again plus at least 14 days of waiting before the retake.
After this course you read a question and know which of the 25 skills it tests. You call the Messages API with streaming, images, thinking and batches and handle every error type. You price a request before you ship it and cut the bill with the right model, prompt caching or a batch. You write prompts that hold, validate what comes back, build tools and an MCP server that fail safely, choose between a workflow and an agent, configure Claude Code for a repository and keep keys and injected input under control. You walk into the exam with a readiness score by domain, and you keep a developer’s kit for your own Claude applications.
