Professional scrum master

- [Presenter] The Professional Scrum Master, or PSM, exam was launched by Ken Schwaber in 2009 after he launched scrum.org. scrum.org does not mandate any training course for PSM. There are three levels of the PSM exam, levels one, two, and three. The Professional Scrum Master level one test is considered equivalent to the Certified Scrum Master test, and there are no renewals required once you achieve any PSM credential. In my opinion, the PSM I exam is of moderate difficulty. PSM II and III are tougher exams. For PSM I, you get 60 minutes to answer 80 questions and you need to get 85% or 68 questions right. You can take the test from anywhere, but you get one attempt and you have to finish the test in one sitting. The exam fee is $150. Access scrum.org and look for open assessments. Those tests are very useful for PSM and other scrum.org certifications.
