How many times can I take the Six Sigma test?
Usually, most institutes do not set a limit for the number of times you can retake the Six Sigma test, but stipulate the gap between one exam and the next, if you need to take it. Check with the institute to get a clearer idea. However, the fee you pay for one take is valid for only that. Every time you retake your Six Sigma test, you have to pay the exam fee afresh.
