PECB-820-40-Six Sigma Green Belt Exam Preparation GuideTAKE A CERTIFICATION EXAMCandidates will be required to arrive at least thirty (30) minutes before the beginning of thecertification exam. Candidates arriving late will not be given additional time to compensate forthe late arrival, and may be denied entry to the exam room (if they arrive more than 5 minutesafter the beginning of the exam scheduled time).All candidates shall present a valid identity card with a picture such as a driver’s license or agovernment ID to the invigilator.The exam duration is three (3) hours.

First and foremost, multiple-choice exam willnot commonly demonstrate if the candidate’s response is right or wrong, additionally it willdemonstrate continuance of the learning process. Because of this particularity, the exam is not“open book” and does not measure the recall of data or information. This type of examinationcan be adapted to the measurement of a wide range of learning objectives including: reasoning,problem solving, exercising judgement, making inferences and demonstrating knowledge offacts through analysis and interpretation of information. At the end of this document, you will findsample exam questions and their possible answers.The exam is “closed book”. The use of electronic devices, such as laptops, cell phones, etc.,is not allowed. Candidates are only authorised to use a hard copy dictionary.All attempt to copy, collude or otherwise cheat during the exam will automatically lead to theexam’s failure.PECB exams are available in English.
