At this time, there is no test required to earn the Certified Scrum Product Owner® (CSPO®) certification; successfully attending the 16-hour course taught by a Certified Scrum Trainer® (CST®) will result in certification.
After completing the course, you'll receive a welcome email from Scrum Alliance® prompting you to accept the license agreement for your CSPO certification. After accepting the agreement, you will be able to download a copy of your certification and share a digital badge that verifies your credential.
