Certified Quality Engineer. Certified Quality Engineer, often abbreviated CQE, is a certification given by the American Society for Quality (ASQ). These engineers are professionally educated in quality engineering and quality control.

They are trained in researching and preventing unnecessary costs through lack of quality, lost production costs, lost market share due to poor quality, etc. They possess the knowledge needed to set up quality control circles, assess potential quality risks, and evaluate human factors and natural process variation.

Professional certification
The American Society for Quality (ASQ) is a professional institute that examines the professional competency of candidates and, if found to be acceptable, awards them with official certification.
This process helps to establish and maintain a minimum body of knowledge and skill level among certified engineers.
The exam changes from test-to-test in minor detail and the body of knowledge is revised and updated by peer review committees set up by the ASQ.

There are two formats for the ASQ certification test:

 Computer Delivered - This CQE examination is a one-part, 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.
 Paper and Pencil - This CQE examination is a one-part, 160- multiple choice question, five-hour exam and is offered in English only.
