CQA Exam Overview 2027
The American Society for Quality (ASQ) Certified Quality Auditor (CQA) certification represents one of the most prestigious credentials in the quality auditing profession. With the 2026 body of knowledge effective from April 1, 2026, the CQA exam has been updated to reflect current industry practices and emerging trends in quality management systems.
The CQA examination consists of 165 multiple-choice questions, with 150 scored and 15 unscored pretest questions. Candidates have 5 hours and 18 minutes to complete the exam, which is administered through Prometric testing centers. The exam follows an open-book format, allowing candidates to reference approved materials during the test.
The updated body of knowledge emphasizes digital audit technologies, remote auditing capabilities, and integration with Industry 4.0 practices. These changes reflect the evolving landscape of quality auditing in modern manufacturing and service environments.
Understanding the complete pricing breakdown for CQA certification is essential for budget planning. The initial exam fee is $550 for non-ASQ members ($450 for members), with retake fees of $350 ($250 for members). Given the comprehensive nature of the exam, many candidates benefit from structured preparation to avoid retake costs.
Domain 1: Auditing Fundamentals (25%)
Domain 1 forms the foundation of quality auditing knowledge and represents 25% of the exam content. This domain covers essential principles, standards, and regulatory requirements that govern audit activities across various industries.
Core Knowledge Areas
The complete study guide for Domain 1 covers four primary knowledge areas:
- General Knowledge: Quality concepts, customer-supplier relationships, and basic quality principles
- Quality Standards and Guidelines: ISO 9001, AS9100, ISO 14001, OHSAS 18001, and industry-specific standards
- Regulatory and Legal Issues: FDA regulations, legal implications of audit findings, and compliance requirements
- Quality Management Systems: Process approach, risk-based thinking, and continual improvement principles
Candidates must demonstrate comprehensive understanding of quality management principles and their application in various organizational contexts. The questions in this domain often present scenarios requiring application of standards to real-world situations.
Focus on understanding how different quality standards complement each other rather than studying them in isolation. Many exam questions test your ability to apply multiple standards within a single audit scenario.
| Standard | Primary Focus | Key Audit Elements |
|---|---|---|
| ISO 9001 | Quality Management | Process approach, customer focus, leadership |
| AS9100 | Aerospace Quality | Configuration management, risk management, project management |
| ISO 14001 | Environmental Management | Environmental aspects, legal compliance, lifecycle perspective |
| ISO 45001 | Occupational Health & Safety | Hazard identification, worker participation, incident investigation |
Domain 2: Audit Process (30%)
As the largest domain, Audit Process accounts for 30% of the exam content and represents the core competency expected of certified quality auditors. This domain encompasses the entire audit lifecycle from planning through follow-up activities.
Audit Planning and Preparation
Effective audit planning forms the cornerstone of successful audits. The comprehensive Domain 2 study guide details the critical elements of audit preparation:
