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.
  • You have eight (8) weeks in which to take the certification examination. You can decide during that time when to begin.
  • You will have four (4) hours to complete the examination once you begin, and you cannot pause or restart the examination clock. The questions are selected randomly from a bank of questions.
  • You may take the exam only once.
  • You must have a passing score of seventy (70) or better. Your score will be posted upon completion of the exam.
  • You will receive a certificate in the mail six to eight weeks after the end of the two-month term signifying your certification in Green Belt, Lean Sensei or Lean Black Belt, as it applies.
  • Students who do not take the exam in the eight-week term period or those who do not pass it may re-take the exam at the re-take fee rate listed in the above chart.


Re-certification is required every three years to ensure that students maintain the same level of knowledge demonstrated on their first exam. Students can become re-certified when they earn Continuing Education Units (CEUs) by taking any two of the Villanova courses listed below. A minimum of nine CEUs is required, and a $50 re-certification fee will apply.
