ExploreAbout this exam
The Certified Reliability Engineer (CRE) is a professional credential for people who specialize in improving the reliability, maintainability, and safety of products, systems, and processes. According to ASQ, the certifying body, a CRE focuses on identifying potential failures, optimizing performance, and ensuring compliance with quality and reliability standards. The program is accredited by the ANSI National Accreditation Board under ISO 17024. It suits engineers and technical professionals whose work involves reliability prediction, testing, maintenance planning, and safety analysis rather than general quality control. Eligibility requires eight years of on-the-job experience in one or more areas of the CRE Body of Knowledge, with at least three of those years in a decision-making position; a college or technical-school credential waives part of that requirement. The exam is multiple choice and tests comprehension of the Body of Knowledge, which is published as a downloadable document with subtext and cognitive levels. All exams are open book, so preparation means working through the BoK topics, the listed references, and plenty of calculation practice with bound reference materials you can actually carry into the test room. ASQ offers books and training to help candidates prepare.
What you'll study
About CRE preparation
What is the exam format?
Computer-delivered CRE is a one-part, 165-question multiple-choice exam offered in English only; 150 questions are scored and 15 are unscored. Total appointment time is four and a half hours, with 4 hours and 18 minutes of exam time. Paper-and-pencil sittings are 150 questions over four hours in English, Korean, or Mandarin at certain locations.
Is the exam open book?
Yes. All ASQ exams are open book, and you bring your own reference materials. Everything must be permanently bound by stitching or glue, or fastened securely in its cover with ring, spiral, or plastic snap binders, brads, or screw posts. Hand-stapled documents, unbound notes, and slide or wheel charts are prohibited. The test administrator inspects references before entry.
What calculator can I bring?
Computer-based exams include a basic scientific calculator on-screen, and a hand-held basic calculator is available on request. You may bring any silent, battery-operated, hand-held calculator with no programmable memory. Programmable models with graphing or text-storage capability, such as the TI-89, are not allowed.
How hard is the CRE, and what trips people up?
The BoK spans reliability statistics, prediction, testing, maintainability, and safety, so the common failure is over-weighting one area. Candidates often under-prepare on quantitative topics and on maintainability and safety, then lose time hunting for formulas in unfamiliar references. Tab your bound books before test day and rehearse calculations under timed conditions.
What score do I need to pass?
ASQ does not publish a passing score on the CRE page, so no numeric target can be confirmed from the official source. Prepare to answer accurately across the whole Body of Knowledge rather than aiming at a known cutoff. Treat every domain as scored, since the BoK topics define what the questions measure.
How quickly do I get results?
Computer-based candidates see a result immediately after submitting the exam, and within 3-5 business days receive an email confirming it. ASQ then sends separate instructions for claiming the digital certificate and badge. Results for pilot exams with updated or new Bodies of Knowledge are communicated within five weeks, and paper-based results are slightly delayed.
What happens if I fail?
You receive a performance summary by email within 3-5 business days of the initial exam. For two years from your previous attempt you can reapply at a significantly reduced retake rate. Use the summary to find weak BoK areas before rescheduling, and check ASQ's exam results FAQ for details.
How do I schedule, and what if I need to reschedule?
After approval you get an eligibility email within 1-2 business days with instructions to schedule with Prometric. To change an appointment, act at least five days before your date through Prometric's website or automated voice system; the fee is $130. For translated paper-based exams in China, reschedule at least 45 days ahead.
How early should I arrive, and what ID do I need?
Plan to arrive 30 minutes before your appointment for check-in. Bring one valid, government-issued photo ID with a signature, and the name must match your application. Arriving late means you cannot test and you forfeit the exam fee, so build in travel margin.
In what order should I study the Body of Knowledge?
Start with the BoK document and its subtext, which states the cognitive level tested. Then work through the references ASQ lists, since questions are based on them. Sequence study from reliability fundamentals and statistics into prediction, testing, and maintenance, finishing with safety and the management topics, so quantitative methods get repeated practice.
