To be effective, Scrum Masters need to have a rock-solid understanding of the practices and values of Scrum. The Professional Scrum Master (PSM) assessments allow people to validate their understanding of those practices and values, and how they would respond to situations that challenge them.
Professional Scrum certification is highly recognized in the industry as the only Scrum certification based on testing of knowledge and understanding and therefore are significantly more valuable than available alternatives for Scrum. Scrum.org certification does not require retesting nor does it require future payments to retain certification status. There are three options for Scrum Master assessment and certification: PSM I, PSM II and PSM III.
We strive to ensure that they remain valuable and relevant through frequent inspection and adaptation of the assessment content.
