Open Assessment (60 minutes, no certification, 75% score)
The open assessment of Scrum knowledge continues to be available free to anyone interested in testing their knowledge of Scrum, or in preparing for certification. The assessment has been shortened to 50 questions (randomly selected from a pool) to reduce the amount of time it takes to complete. The passing score is the established average achieved by the 1,000 test-takers during the development of this assessment.
PSM I (90 minutes, PSM I Certification, 90% minimum score)
The fundamental assessment of Scrum knowledge is available to anyone interested in demonstrating their knowledge of Scrum, and in achieving certification. A $100 fee will be charged for this assessment. Individuals demonstrating an acceptable level of knowledge will be issued a certificate and listed as a Professional Scrum Master I.
PSM II (120 minutes, PSM II Certification, 85% minimum score)
The intermediate assessment of Scrum knowledge and skill is available to anyone who wishes to demonstrate their capabilities in applying Scrum to solve complex problems, and in achieving certification. As many of the answers require written responses (and consequently must be graded by a human) a fee of $500 will be charged for this assessment. Individuals demonstrating an acceptable level of knowledge and skill will be issued a certificate and listed as a Professional Scrum Master II.
PSD I (.NET) (90 minutes, PSD I, 90% minimum score)
The fundamental assessment of skills needed for developing software using Scrum will be available only to those individuals that attend a Professional Scrum Developer course for the first year.
