CSM(Certified Scrum Master) Vs PSM(Professional Scrum Master)


Ken Schwaber and Jeff Sutherland first co-presented Scrum at the OOPSLA Conference in 1995. It essentially documented Ken and Jeff’s learning over the previous few years and made public the first formal definition of Scrum.

The first version of the Scrum Guide was released in 2010 to help people worldwide understand Scrum. The Guide has evolved since then through small, functional updates. Ken Schwaber and Jeff Sutherland, together,  stand behind the Scrum guide.

One of the popular certifications is Scrum Master certification, and we have two main certifications available in the industry, which I think is authentic for Scrum Masters. Now let me summarise my understanding of the differences between Certified Scrum Master (CSM) and Professional Scrum Master (PSM)
