CQE Full Mock Exam (90 Minutes) is a timed-format practice set for candidates preparing for the ASQ CQE examination. The questions follow the structure, tone and difficulty distribution of the real exam, with a deliberate mix of straightforward recall items, applied scenarios and short calculations so that your practice score is a realistic predictor rather than a flattering one.
Exam mode hides feedback until you submit, runs against the clock, and then gives you a complete question-by-question review. This is a premium quiz; access is granted per quiz or as part of the certification bundle.
Every explanation does three things: it names the underlying principle, it explains why the correct option is correct, and it explains why the most tempting distractor is wrong. That last part matters more than most candidates expect, because the ASQ exam is built around plausible distractors that reflect genuine misconceptions in practice. Learning to recognise them is the single fastest way to raise a borderline score.
The set is drawn from the Certified Quality Engineer Body of Knowledge and each question is tagged with its BoK reference. When you finish, the review screen groups your incorrect answers so you can see immediately whether your gap is concentrated in one area or spread thinly across the syllabus. Concentrated gaps are good news: they are the quickest to close.
We recommend working through the free quizzes first to calibrate, then using the premium sets for depth. Aim to score comfortably above the pass threshold on exam-mode practice before booking your exam date, and repeat any quiz where you scored below seventy percent after leaving at least two days between attempts so you are testing recall rather than short-term memory.
If you want structured teaching alongside this practice, our full preparation course covers the same Body of Knowledge with video lessons, worked examples and downloadable templates.

Q1.A control chart signals that a process is out of control when a point falls beyond the control limits. What do the control limits represent?
- A.Customer specification limits
- B.The voice of the process, typically ±3 sigma of the plotted statistic✓ Correct answer
- C.The tolerance agreed with the supplier
- D.The economic limits of scrap cost
Explanation
Control limits are calculated from process data and describe the natural variation of the process, usually at ±3 standard deviations of the plotted statistic. Specification limits come from the customer and are never plotted on a control chart. Confusing the two is one of the most common SPC mistakes.

Q2.Which control chart is most appropriate for monitoring the number of defects per unit when sample size varies?
- A.p chart
- B.np chart
- C.c chart
- D.u chart✓ Correct answer
Explanation
The u chart plots defects per unit and handles varying sample sizes because the count is normalized by the inspection unit. The c chart requires a constant area of opportunity. p and np charts track defectives, not defects.

Q3.Cp for a process is 1.67 but Cpk is 0.85. What does this indicate?
- A.The process has excessive variation
- B.The process is centred but incapable
- C.The process is capable but off-centre✓ Correct answer
- D.The measurement system is unreliable
Explanation
Cp measures potential capability from spread alone, while Cpk also accounts for centring. A high Cp with a much lower Cpk means the spread is fine but the mean has drifted toward one specification limit. Recentring the process would bring Cpk close to Cp.

Q4.In a gauge R&R study, which component represents the variation observed when the same operator measures the same part repeatedly?
- A.Reproducibility
- B.Repeatability✓ Correct answer
- C.Stability
- D.Linearity
Explanation
Repeatability is equipment variation: the same appraiser, same part, same gauge. Reproducibility is the variation between different appraisers. Together they form gauge R&R.
