Content Determination for the ATMAE Lean Six Sigma ExamThe content for this exam was derived by surveying certified lean six sigma black belts from across theUnited States from a wide range of companies and government entities that varied in size, productsproduced, and services provided. It should be noted that all the information on this exam is important,however, certain content areas are used more often on the job than others, thereby, those content areasreceived more emphasis on this exam. This was noted by the order the content areas were ranked and bythe comments from those surveyed.Belt Distinctions for the ATMAE Lean Six Sigma ExamDepending upon the grade earned by the examinee taking this exam, an examinee can earn one of threedifferent belt distinctions. If the examinee earns approximately a 40-59% on the exam (cutoff passingscores are evaluated annually), then he or she will be classified as a Lean Six Sigma Yellow Belt. Anexaminee earning a score of 60-79% will be classified as a Lean Six Sigma Green Belt. All examineesearning a score of 80% or higher on the exam will be classified as a Lean Six Sigma Black Belt.Individuals who would like to be classified as Lean Six Sigma Master Black Belts will have to submit a leansix sigma project that they have completed as well as one from an individual that they are assisting withon a project. All projects must be preapproved by the ATMAE Certification Board before being initiated.Candidates will have up to three years to complete the projects once final approval is given by the ATMAECertification Board. An additional fee is charged for reviewing the projects. In addition, all projects musthave the approval by the candidate’s supervisors and a financial statement must be included with thesubmission of the project. Further details regarding project format can be obtained by contacting theATMAE office.Composition of the ATMAE Lean Six Sigma ExamThe ATMAE Lean Six Sigma exam covers 12 main content areas and is further divided into 88subcategories. The exam is divided into two main parts: the first part consists of 100 multiple choicequestions that are worth 1 point each. The second part of the exam is composed of 25 multiple choicequestions that require an examinee to solve a production or statistical problem that may take severalminutes. Because of the time constraints, these questions are worth 4 points each. Therefore, each of theparts is worth 100 points and the combined scores from these two parts are used to calculate theexaminee’s final score on the exam. A printout of how well the examinee performed on each of the 12main areas and 88 subcategories is emailed to them once all their fees have been paid. The emailedprintout is a useful instrument to the examinee for reviewing any areas of weakness in case he or shewould like to retake the exam to earn a higher belt distinction. Textbooks from which the content for thisexam was developed from are listed after the sample questions section of this study guide.
