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.
Those that pass the PSM assessments will receive the corresponding industry recognized certification. There are two options for Scrum Master assessment and certification: PSM I and PSM II. These assessments are sequential, meaning that the PSM I must be passed before attempting the much more difficult PSM II.
The value of certification is intimately tied to the demonstration of knowledge needed to achieve it. By that measure, the PSM assessments are significantly more valuable than available alternatives for Scrum. And, we strive to ensure that they remain valuable and relevant through frequent inspection and adaptation of the assessment content.
