What is the difference between CSM and PSM?

The Certified ScrumMaster (CSM) and the Professional Scrum Master (PSM) are two of the most recognized certifications in the Scrum community. While both focus on Scrum principles, they differ in their approach, requirements, and recognition.

Key Differences

• Certification Body: CSM is offered by the Scrum Alliance, while PSM is provided by Scrum.org.
• Training Requirement: CSM requires attendance in a two-day training course taught by a Certified Scrum Trainer (CST). PSM does not have a mandatory training requirement, although attending a course can be beneficial.
• Exam Format: CSM has a multiple-choice exam that you take after the training, while PSM features a more challenging online exam that tests your knowledge of Scrum principles.

Recognition and Validity

Both certifications are well-respected in the industry. CSM is often seen as more accessible due to its training requirement, making it a good entry point for new Scrum Masters. PSM, on the other hand, is considered more rigorous, appealing to those with a deeper understanding of Scrum or those who prefer self-study.

Considerations

• Cost: CSM classes start at around $399, which includes training and exam fees. PSM costs $150 for the exam, with optional training costs.
• Career Path: Both certifications can enhance your career, but the choice may depend on your learning style and professional goals.

In our experience, many practitioners find value in both certifications. If you're new to Scrum, CSM might be the better starting point. For those with experience, PSM can offer a deeper challenge.
