The Scrum Alliance just announced through a press release the Added Qualifications [PDF] program. From the release:
The Added Qualifications program will begin by first offering courses in Scaling Scrum Fundamentals. Those interested in earning an Added Qualification in Scaling Scrum Fundamentals will need to hold at least one of two foundational certifications, Certified ScrumMaster® or Certified Scrum Product Owner®.
More information can be found on the Scrum Alliance Added Qualifications page.
Through World Mindware, we will be introducing courses over the next months to help you achieve these new Added Qualifications.
