Six Sigma Certification Exam

In order to best prepare for the exam, please note the following exam expectations:*

  • Spend at least 200 hours preparing for the exam even if you already have some background in Six Sigma.
  • Once you begin your certification exam, you cannot pause or restart the examination clock. The questions are selected randomly from a bank of questions.
  • You must have a passing score of seventy (70) or better. Your score will be posted upon completion of the exam.

*Select courses that have an associated optional certification exam post their completion. Certification is awarded upon passing the exam which must be taken within twelve months of completing the associated course. The Master Black Belt certification exam must be taken within six months of completing the Lean Six Sigma Master Black Belt course.

Students who do not pass the exam are permitted to retake it two times at the retake fee (maximum of three failures). If a student fails the exam three times, they will be required to retake the requisite course at the full tuition rate prior to retaking the exam. A maximum of three months is permitted between retakes. Students who do not attempt the certification exam within one year (six months for Master Black Belt) of taking the course or do not retake the exam within the three-month time frame will be required to retake the requisite course prior to sitting for the exam.
