Agile & Scrum


How do they compare against each other? PSM vs CSM?

PSM and CSM would be really helpful with your career transition, into Scrum Master Role. However, if one really wants to compare one against the other, there are a few things that I would like to highlight.

As one can see, PSM I has a challenging time limit as it comes with a single attempt ONLY and has a hard pass mark, while for CSM; time limit is not very challenging as you need to answer a lesser number of questions and you get multiple attempts too.

There is also a general perception that Scrum Alliance certifications are typically better known & recognized by US-based companies, whereas in Europe, Scrum.org seems to have a much bigger presence but there is really no hard evidence to prove this.

In short, PSM “journey” helped anyone what Scrum is actually about. It seems to be more real world – in practice but you will always find people calling out, that there is less proof of training.

Number of attempts Multiple One attempt only (although an additional free attempt is given to those who attend the PSM training, in case they fail to clear the test in their first attempt)
Difficulty of Assessment Easy (almost impossible to fail) It’s not straightforward so needs an intermediate understanding of Scrum.

Mandatory course offered by CSTs.
Course materials also vary significantly in both content & quality depending on the instructor.
The course is NOT Mandatory but there is an optional course offered by PST’s in case you need one.
Pretty standard course material owned by PSTs and created by Ken Schwaber.
