The Certified Quality Engineers (CQE) are professionals who understand the principles of product and service quality evaluation and control.

This is one of the oldest certification (and the difficult to pass the exam) offered by ASQ. The exam consists of 175 questions, and out of these 160 questions are evaluated for scoring.

##### Eligibility:

##### Exam Details:

The computer-based CQE examination consists of 175 multiple choice question, five-and-a-half-hour exam and is offered in English only. 160 multiple choice questions are scored, and 15 are unscored. You will not know whether a question is scored or not scored.

It is the open book exam. You can take any book or binder in the exam. Loose sheets and multiple choice questions are not allowed in the examination room.

You need 550 marks out of 750 to get certified. However these marks are not calculated simply by dividing the correct answers divided by total number of questions. Instead ASQ does do the balancing to ensure that difficulty of the particular exam is taken into consideration.

##### Body of Knowledge:

Here is the break down of questions:

Section | Topic/Area/Category | Number of Questions | Questions (%) |
---|---|---|---|

I | Management & Leadership | 18 | 11% |

II | The Quality System | 16 | 10% |

III | Product & Process Design | 23 | 14% |

IV | Product & Process Control | 25 | 16% |

V | Continuous Improvement | 27 | 17% |

VI | Quantitative Methods & Tools | 36 | 23% |

VII | Risk Management | 15 | 9% |

If you look at this table, you will see that around one-fourth of questions are from Section VI, which is Quantitative Method and Tools. This section, in fact, is the "Statistics."

Now lets come to the question of how to prepare for the exam, what are the resources?

**Certified Quality Engineer (CQE)**

**2 FULL LENGTH MOCK TESTS**

##### Suggested Study Material:

I would recommend The Certified Quality Engineer Handbook for study, and The ASQ CQE Study Guide for practice questions.

In addition to these two resources, I will also recommend my Quality Engineering course available on Udemy. This course is based on the ASQ CQE Body of Knowledge and covers all topics in plain and simple language.

I also a have a CQE Exam Preparation Quiz where you can attempt two full length tests. There is a clear explanation for each question. In addition, I have Probability and Statistics Practice Tests available on Udemy. This course provides 100+ questions with video solutions.

##### Recommended Online Training Courses:

In addition to the Certified Quality Engineer Training course, we strongly suggest following courses to give you in depth knowledge of some of the topics. These courses will definitely improve the chance of passing the CQE exam on your first attempt.

**Calculator:**

ASQ does not allow programmable calculator in the exam. It does suggest a list of calculators allowed in the exam. Most commonly used calculator is TI-30Xa. This is a simple calculator and has statistical functions.

However, we suggest Casio fx-991MS or **Casio fx-991EX** (Best Choice) for the exam. This is a scientific calculator.

Casio fx-991MS and fx-991EX can perform many advanced functions quickly, without needing to actually use complex formulas and tables. Some of these advanced functions include:

- Finding out the mean and standard deviation of a group of numbers

- Solving the Simple Linear Regression questions (You will not believe how easy it is if you have not used a scientific calculator like fx-991MS or 991EX)

- Normal Distribution questions (You will not need to open the Z-table to solve them)

- Solving equations with one, two or three unknowns

- Using calculator memory for complex calculations

- Our **preferred option is Casio fx-991EX**, as this can solve probability distribution (Normal, Binomial and Poisson) questions without needing to use the formula or tables.

Get used to the calculator that you will use in the exam. We have a course on how to efficiently use Casio fx-991MS and Casio fx-991EX calculator. Click here for a special discount.
