Prepare for the ASQ Certified Quality Auditor (CQA) exam by linking each conclusion to its requirement and evidence. Work through the two document-based exercises, then use the five-domain map to identify the rest of your preparation needs.
Who is this CQA guide for?
CQA tests general quality auditing under the 2026 Body of Knowledge, effective April 1, 2026. A welding-industry background can provide context for study, but the credential has its own ASQ syllabus.
Eligibility requires eight years of relevant full-time paid experience, including three in a decision-making position. This means authority over projects or processes and responsibility for outcomes; a manager title is not required.
One qualifying education waiver may reduce the eight-year total: one year for a technical or trade diploma, two for an associate degree, four for a bachelor’s, or five for a master’s or doctorate. ASQ lists the three-year decision-making requirement separately. Check your documented experience against the current application requirements.

What does the current CQA outline cover?
The five domains total 150 scored questions. Use the official counts and your practice gaps together when choosing what to revisit.
The counts are scored questions, not percentages. The full Body of Knowledge lists individual tasks and the highest cognitive level at which each can be assessed.
| BoK domain | Scored questions | A useful review task |
|---|---|---|
| I. Auditing Fundamentals | 37 | Compare audit purposes, criteria, roles and professional conduct. |
| II. Audit Process | 45 | Follow planning, evidence collection, reporting and corrective-action follow-up. |
| III. Auditor Competencies | 30 | Practise communication, interviewing, conflict resolution and team tasks. |
| IV. Audit Program Management and Business Applications | 23 | Connect audit resources and risk to business and program needs. |
| V. Quality Tools and Techniques | 15 | Review quality tools, basic statistics, sampling and risk methods. |

Practise stating a certificate-documentation finding
Name the requirement, identify the relevant record and state the gap. Keep documentation conclusions distinct from conclusions about the physical material.
This original exercise defines its complete document set and fictional purchase-order criterion. No welding-code acceptance rule is needed.
Worked practice
For this fictional exercise, purchase order P7 requires each delivered lot to have a material certificate bearing a signature. Your audit covers receiving documentation only. The complete certificate file for the three delivered lots shows signed certificates for A and B, and an unsigned certificate for C. What finding does this support, and what does it not establish?
Show the answer
P7 requires a signed certificate for each delivered lot, but lot C’s certificate is unsigned. The signed-certificate requirement is therefore unmet for lot C. The provided A and B certificates meet that signature requirement. This does not establish that the order meets every P7 requirement.
The unsigned certificate supports a documentation finding. It does not demonstrate a physical material defect, a supplier-wide failure, a weld-acceptance result or a need to scrap material. No severity-grading rule is given. Because P7 requires a signature for every lot, the C gap cannot be dismissed merely because A and B have signatures.

Practise checking a closure package against its rule
A memo and training roster document activities. Whether they are enough for closure depends on the stated requirements and the verification evidence supplied.
The current outline includes evaluation and follow-up of corrective action. This second original exercise supplies an explicit fictional closure rule so the decision does not depend on an unstated organizational policy.
Worked practice
A fictional audit found that inspection records were signed before inspection was performed. For this finding, closure rule R2 requires documented implementation of the response and a completed follow-up verification check showing that inspection now precedes signing in all records required by that check. Assume a submitted memo and training roster confirm implementation. The complete closure package contains no completed follow-up verification check. Does this package meet R2, and what evidence is missing?
Show the answer
No. Implementation is confirmed, but the completed follow-up verification check required by R2 is absent. Obtain and evaluate that required check before concluding that the stated closure conditions are met.
The decision follows R2’s two conditions. Missing verification evidence does not itself prove that pre-signing continues, that current records are defective or that training was ineffective. Nor do the memo and roster demonstrate that the required verification check passed. Keep “not yet demonstrated” distinct from “demonstrated failure.”

How can you turn practice errors into a study plan?
Map each missed or guessed answer to the current Body of Knowledge task. Identify whether you need to revisit the concept, calculation, evidence or reference lookup.
Choose preparation materials by their coverage of the current outline. Compare an existing book’s contents with that outline before deciding what needs supplementing. Adapt your study time to the gaps you find rather than adopting a fixed preparation period.
- For each practice scenario, list its requirement, evidence and scope before writing the conclusion.
- For closure questions, separate implementation evidence from the required follow-up result.
- For sampling questions, identify the population and selection method; do not turn a sample percentage into an exact population fact.
- For reference practice, locate a topic in your permitted bound material and explain how it applies.

What should you expect on the computer-based exam?
The CQA computer-based exam contains 165 questions: 150 scored and 15 unidentified, unscored pretest items. You have 318 minutes to answer them; the appointment is 330 minutes.
ASQ uses a scaled passing score of 550 out of a possible 750. This is not a raw percentage or a fixed published number of correct answers. A practice-test percentage cannot be converted into the official scaled result.
Check the current registration page and candidate handbook for the language, delivery mode, application dates and fee that apply to your booking. Paper-based forms can differ from the computer-based figures above.
Approximately 10–15% of CQA questions are case studies with supporting audit documents. These use the same four-choice format within the exam; practise reading the relevant documents with the question.

What does open book allow?
Use securely bound references and notes that remain bound during the exam. Electronic reference copies and collections of questions and answers are prohibited by the candidate handbook.
Prepare any permitted tabs before entry. If a reference contains practice questions or refresher quizzes, follow the handbook’s requirement to remove or obscure them. Studying with a question bank does not make it a permitted exam reference.
Confirm calculator and scratch-work rules for your delivery mode. A test-center appointment supplies scratch paper; remote testing uses the software Scratchpad. Do not apply the test-center paper rules to a remote exam.
