CCAO-F reports on a scaled range of 100–1000 with a cut at 720, and its questions are distributed across 7 domains by published weight rather than evenly. Those weights are the single most useful thing in the exam guide: they tell you where the marks are, and they rarely match where candidates spend their time.

Output Evaluation and Validation is the heaviest at 21.0% — roughly 13 of the 60 questions. Weakness there costs more than weakness anywhere else, which is exactly what a flat percentage score hides and what a blueprint-weighted estimate surfaces.

Where to start

Three objectives carry the most weight on CCAO-F. Between them they are worth roughly 11 of the 60 questions:

Which is not the same list as the objectives that feel hardest, and that gap is where study time usually goes missing. A week spent on the topic that worries you most is a week spent on 6% of the exam at best, and often on far less.

How we practice it

Our CCAO-F bank holds 380 original items across 21 objectives, each with an explanation and a note on every option — why the right answer is right, and why each distractor fails. Items are written against the published objectives. None is recalled or reproduced from a live exam.

A drill allocates questions by the published domain weights, multiplied by how far your measured mastery sits below standard. So a domain worth 21% of the exam that you are weak in dominates your next sitting, while one you have already mastered drops back to an exposure floor that keeps its estimate current.

What a question looks like

Taken from the free CCAO-F set, not written for this page — the correct answer, why it is correct, and a note on why each other option fails. Scenarios, not recall: nothing here is answerable from a definition.

CCAO-F Checking factual accuracy and grounding

An employee supplies a policy document and asks a question about it. The answer is fluent and cites a section number. What is the most reliable way to check it?

A Open the cited section in the supplied document and read it

Correct. The document is in hand, so the citation can simply be checked — direct, conclusive, and quick.

B Ask the same question in a new conversation and compare the two answers

Agreement between two runs is not evidence: both draw on the same tendencies and can be consistently wrong.

C Ask the model how confident it is in the answer

A confidence statement is produced the same way the answer was, so it inherits the same uncertainty rather than measuring it.

D Judge by the fluency and internal consistency of the answer

Fluency and internal consistency are properties of the writing and hold just as well for an incorrect answer.

The source is available, so verification is a matter of reading it — the cheapest and most conclusive check there is. Fluency is unrelated to accuracy. Two conversations can agree and both be wrong, since they share the same tendencies. A stated confidence level is generated text, not a measurement of correctness.

What you get for free

A 20-item diagnostic for CCAO-F, spread across objectives rather than taken off the top, so the sample reflects the shape of the exam. It produces a first readiness estimate and full explanations, whether or not you go on to buy.

The other Claude certification exams

All four report on the same 100–1000 scale with the same 720 cut, so a readiness estimate means the same thing whichever you are sitting. What differs is shape:

Domain	Share of exam	Approx. questions
Domain 1 — Prompting and Task Execution	14.0%	8
Domain 2 — Output Evaluation and Validation	21.0%	13
Domain 3 — Product and Model Selection	12.0%	7
Domain 4 — Workflow Integration and Solution Design	16.0%	10
Domain 5 — Configuration and Knowledge Management	12.0%	7
Domain 6 — Governance, Risk, and Responsible Use	15.0%	9
Domain 7 — Troubleshooting and Optimization	10.0%	6
