Lean Six Sigma White Belt exam: Actual questions & answers

To complete your certification for the Lean Six Sigma White Belt level, you need to complete an exam. If you have followed the content of the course well, have listened to your instructor intently and have completed any practical work given during the course, the exam should be very straightforward.

It is worth noting that the way in which the Lean Six Sigma White Belt exam is presented will vary depending on the instructor, the institution delivering the training and the industry within which the trainees come from. With that said, there is a general consensus around the types of questions to be asked and the format they should be asked in.

The aim of the exam is not to make certifying difficult or to trip you up. It is really about ensuring you have understood the content well, you really grasp the concepts of Lean and Six Sigma and you are ready to move to the next level – Yellow Belt.

Let us now look at the Lean Six Sigma White Belt examination in more detail.

Lean Six Sigma White Belt exam: Question Format

Typically, a Lean Six Sigma White Belt examination will be a straightforward, multiple-choice exam. For each question presented, you will have around 4 options (A – D) to choose from, and generally, you will need to choose one of the options. Some exams will offer this format throughout for around 20 questions in total.

Other formats may use the multiple choice option for around the first 10 questions, and then mix it up. For questions 11 – 15, options may include “fill in the blanks”, where statements are given relating to White Belt topics with a word or phrase missing. This is there to test your memory of the content as often the sentences will be lifted from the training content itself.

Additionally, you may come across true or false statements for the final 5 questions. These will be directly linked to the topics in the course, where one particular topic is taken and a scenario is attached to it (for example – X is an example of something which is a value add, true or false).

When it comes to the Lean Six Sigma White Belt examination, these are the potential formats to be mindful of but do remember that they will differ depending on the parameters set out above.

It is also worth noting that the exam is open book, so any training pack or materials you have been given can be brought with you into the exam. It is not just about answering questions but ensuring you really engage with the content.
