• 

  PSM I

  Professional Scrum Master I

  A working command of the Scrum framework and of the Scrum Master's accountability — serving the Scrum Team, the Product Owner and the wider organisation rather than administering a process.

• 

  PSM II

  Professional Scrum Master II

  The advanced level: applying Scrum under real conditions, coaching teams through impediments that sit outside their control, and leading by serving instead of directing.

• 

  PSD I

  Professional Scrum Developer I

  The engineering half of Scrum — test-driven development, continuous integration, refactoring and DevOps practices used to produce a genuinely releasable Increment every Sprint.

• 

  PSPO I

  Professional Scrum Product Owner I

  The Product Owner's accountability: maximising the value of the product, owning the Product Backlog, and keeping the team's work connected to product strategy.

• 

  SPS

  Scaled Professional Scrum (Nexus)

  Scaling Scrum past a single team with the Nexus framework — surfacing dependencies between teams early and integrating their work into one Increment.
