Definitely. No one will dispute how up-to-date your expertise is if you have your scrum.org credentials and your resume demonstrates that you've been performing scrum within the previous few years. PMI-accredited professionals state that Scrum.org's trainings are the finest in the business and were crucial in helping them grasp the fundamentals of Scrum. They suggest that PSM courses, especially PSM 2 and 3, be taken in person. While taking a course can help you get started with Scrum, it won't turn you into an expert overnight. You'll also need the will to continue improving and learning as you experiment.
