The CSM (Certified ScrumMaster) and PSM (Professional Scrum Master) certifications both validate Scrum expertise but differ in approach.
CSM, offered by Scrum Alliance, requires attending a mandatory course with a Certified Scrum Trainer, emphasizing interactive learning, making it more beginner-friendly. In contrast, PSM, provided by Scrum.org, does not require a course, allowing for self-study, but its exam is generally considered more challenging.
The choice between them depends on personal learning preferences, budget, and career goals. CSM is ideal for those who prefer structured, instructor-led training, while PSM suits those who are comfortable with independent study and a more rigorous exam. Recognition may vary by region or industry.
