INFORMATIONCertified Quality InspectorThe Certified Quality Inspector (CQI) is an inspector who, in support andunder the direction of quality engineers, supervisors, or technicians, can usethe proven techniques included in the body of knowledge. Under professionaldirection, the CQI evaluates hardware documentation, performs laboratoryprocedures, inspects products, measures process performance, records data,and prepares formal reports.CQIWork ExperienceComputer Delivered – The CQIexamination is a one-part, 110question, four-and-a-half-hour examand is offered in English only. Ofthese questions, 100 are scoredand 10 are unscored.CQI requires two years of workexperience, OR successful completionof an ASQ-approved* accreditedtechnical/apprenticeship trainingcourse. If you do not have a highschool diploma or GED, you musthave THREE additional yearswork experience.Paper and Pencil – The CQIexamination is a one-part,100-question, four-hour examand is offered in English only.*Requires preapproval.Please contact cert@asq.orgfor more details.For comprehensive exam information on the Quality Inspector certification,visit asq.org/cert.Certified Quality Inspector3
