PSM vs. CSM: Explaining the Certification Process

If you want to work with Scrum, you should gain certification. Each certification has its unique process.

CSM Certification Process

  • You have to attend a live online or in-person course taught by a Certified Scrum Trainer or receive training from a Certified Agile Coach (CAC). The training period is between 14 and 16 hours.
  • Once you finish the course, you must take the 50-question CSM test and answer 37 out of the questions correctly within the one-hour time limit.
  • Once you pass the CSM test, you will be requested to accept the CSM License Agreement and complete a Scrum Alliance membership profile. Your membership is good for two years.

PSM Certification Process

  • If you feel confident in your PSM I knowledge, you don't have to take a course. Instead, you can apply to take the PSM I exam. However, the course improves your chances of passing the exam on your first try.
  • Study for the test and take advantage of any learning resources.
  • Pass the test and receive your certification.

PSM vs. CSM: What is the Difficulty Level of Each Exam?

Let's face it; difficulty is a subjective concept. Some people can breeze through the most demanding tests as if nothing happened; others struggle to answer even the most basic questions..

But, as a rule, the Certified Scrum Master exam is easier than the Professional Scrum Master I and II exams. We've already mentioned how the PSM exam doesn't require training class attendance. Although this is excellent for people who don't want to pay for or attend training, those classes exist for a reason; they make it easier for candidates to pass. Therefore, some students who forego voluntary training realize too late that they aren’t well prepared for the exam.
