And you’re done! Let’s see how you did. If you answered nine or more questions correctly you are ready to take a Lean Six Sigma Certification Exam, great! If you answered seven or eight questions correctly, you did well, but you still have studying to do. If you answered less than seven questions correctly you must dedicate time each day to learn the Lean Six Sigma methodologies and concepts before taking a Lean Six Sigma belt exam.

With that said, before going and taking any Lean Six Sigma training and certification exam you find on the internet, you should understand which types of training companies and exams are considered the international standard for Lean Six Sigma training, examination, certification and accreditation. That source would be the International Association for Six Sigma Certification (IASSC).
