Claude Certified Developer vs Architect: CCDV-F or CCAR-F first?

I passed Architect Foundations in July 2026. I compare Developer using its official guide and the 53 practice questions I wrote for it. This site has question banks for both exams, weighted by the domains in Anthropic’s guides. So I also show the difference with examples from both sets.

Developer and Architect Foundations side by side

The table draws on the two exam guides (version 1.0, July 2026) and the certification FAQ. Fees are base fees before any discount.

Plan for about 135 minutes in the seat. Check-in, instructions and a short survey come on top of the 120-minute test. The FAQ names English and Japanese versions, although the panel on each certification page lists only English. Browser translation tools are not allowed.

Your firm’s tier in the Claude Partner Network sets the discount at checkout. A retake costs the same as the first attempt, and an on-time renewal is free. The amounts for each tier are in the breakdown of tier discounts, retakes and renewals for Claude exams.

Where each exam puts its weight

Developer gives the most points to applications and integration: 33.1%. That domain covers Claude API mechanics, application design, configuration and plain software engineering. The guide lists REST, JSON, asynchronous code, version control and code review there. Another 16.8% goes to model selection, tokens, cost and caching. Together that is almost half the exam.

Architect asks first how the system should behave. Agent architecture takes 27%. It covers the agent loop driven by stop_reason, a coordinator with subagents and hooks that enforce a rule. Claude Code configuration takes 20%. It covers the CLAUDE.md hierarchy, rules in .claude/rules/, skills, plan mode and Claude Code in CI.

The out-of-scope list shows the difference best. The Architect Foundations guide leaves out streaming and image analysis. It also skips deploying an MCP server and rotating API keys. For prompt caching, knowing it exists is enough. All of these topics are in the Developer blueprint. Streaming, vision and caching belong to API mechanics, and MCP servers and API keys have skills of their own.

Claude Code runs the other way. In Developer, the Claude Code domain gets 3.1%. CLAUDE.md files and settings.json also appear under configuration management, 4.1% inside the integration domain. Hooks get 1% inside the security domain. In Architect Foundations, Claude Code configuration alone is 20%. If you set up Claude Code for a team, you will find that work mainly in the Architect exam.

Part of the material overlaps. Both blueprints cover tool descriptions, hooks, MCP, prompts and context. Developer more often checks how to write the code. Architect more often checks which decision to make and why.

Same agent, two different questions

Both question sets on this site include a customer-support agent with tools. The same kind of system shows how differently the two exams ask.

In question 35 of the Developer set, an order agent receives three tool_use blocks in one turn. One of the calls times out. The harness sends back results for the other two after a text block and gets a 400 error. You pick the two changes that make the API accept the message. Two rules decide it: the order of the blocks and a result for every tool_use block. The full item and the documentation behind it are at question 35 of the Developer set, taken apart option by option.

In question 3 of the Architect set, the company requires a manager’s approval for any refund above $500. An audit shows the agent issued larger refunds on its own. You choose the way to guarantee the rule. The guide gives this example directly in task statement 1.5: a hook intercepts the tool call and blocks a refund above the threshold. I show how to prove the hook really stops the refund in the refund question from the Architect set.

In the Developer set, a mistake ends in a 400 error. In the Architect set, it ends in a refund nobody approved. The first question checks whether the API will accept your message. The second checks where in the system a business rule has to run.

Associate against the Developer and Architect exams

Associate Foundations (CCAO-F) is for people who use Claude at work and build Projects. It requires no code and no API. Its guide says plainly that the exam is not for people who write code against the API or design agentic systems. Associates hand that work to developers and architects.

Between Associate and Developer, code decides. The Developer guide excludes non-technical users and roles where someone only writes prompts. Associate costs $99 and does not count toward the partner tier. Developer costs $125 and counts.

Between Associate and Architect Foundations, system design decides. Architect tests the agent loop, tools and context. Associate tests whether you can judge the output. Its largest domain, output evaluation, carries 21%. Both exams have 60 questions and 120 minutes.

In question 25 of the Associate set, a board slide shows churn at 4.1% and the appendix table shows 4.6%. Both numbers come from the same export. No code is needed. You have to check the result against its source. The item and its answer are under the question about two churn figures in one deck.

For the full picture, read the post that puts all four Claude certifications side by side, Professional included. It gives the scope, fees and conditions of every exam.

Which exam first, by role

This recommendation follows from the domain weights. Neither the guides nor the FAQ set an order between these two exams.

If you combine two roles, look at your last month of work. More hours on integration code point to Developer Foundations. More hours on decisions about agents, tools and context point to Architect Foundations.

Both exams, and in what order

You can pass both. They are separate certifications with separate fees, both at Foundations level. Neither guide makes the other exam a prerequisite. Anthropic’s certification page says to start at Foundations, then advance to Professional where available. It gives no order between these two exams.

So the order follows from your work. Start with the exam closer to what you do. The second will cover what the first does not test. An engineer moving toward design adds scenarios, agent orchestration and Claude Code configuration after Developer. An architect who wants to show implementation skills adds streaming, vision, caching, token cost, secrets and MCP servers in production after Architect Foundations.

Two exams mean two base fees of $125. Attempt limits apply to each exam separately. Failing one does not stop you from registering for the other.

Both certifications count toward the partner tier, but the tier requirement counts people. Anthropic defines it as how many of the firm’s people hold a current certification and have used Claude in the past 90 days. As I read that definition, a second certificate for the same person adds nobody to that number. The thresholds for each tier and who they count are in the guide to Claude Partner Network tiers.

Only the Architect path has a Professional level. Architect Professional is a separate exam at $175, with no formal prerequisite.

Before you pay, open both guides. Mark the domains you worked in last month and add up their weights in each guide. Book the exam with the higher total first.
