The complete study system
for the CCA certification.
Captured lessons, editorial diagrams, and 15 practice questions across the 5 exam domains — Prompt Engineering, Claude Code, Agentic Architecture, MCP, and Skills.
What is the CCA?
CCA stands for Claude Certified Architect.
It's Anthropic's official credential for engineers who design and ship production systems on Claude — covering prompt engineering, Claude Code development, agentic architecture, the Model Context Protocol, and projects, artifacts & skills. Passing it means you've mastered the whole stack, not just the API.
Prove your Claude expertise
The CCA is Anthropic's official certification for engineers who build production-grade systems with Claude — from prompt design to full agent orchestration.
Ship faster with confidence
Certified architects know when to use extended thinking, subagents, hooks, and MCP — the difference between prototypes and reliable AI systems.
Signal to teams and clients
Whether you're on a hiring loop, pitching a consulting engagement, or standing up an internal AI platform, the CCA is a shared vocabulary.
