The CSM and PSM are the two most common certifications for a scrum master:
The CSM is more common than the PSM but also more expensive. Both offer multiple levels of certification.
You are required to take a class by a certified instructor for the CSM, which will cost you around $1,000. The CSM class includes the test cost and is comparable in difficulty with the PSM test.
The PSM recommends but doesn’t require a course. So you can take the self-study route and then take a cheaper test ($200). This level of affordability can make the scrum.org certifications a more attractive first step for people exploring scrum certifications.
Here is my experience with certifications as a path to growth.
