It is certainly debatable on whether a Scrum certification, backed by a multiple choice test and (potentially) a few days of training, is worth it in terms of opening doors, getting jobs, earning respect, etc.
However, even if you (or a potential employer) couldn’t care less about the “resume stamp” of a professional Scrum certification, maybe there’s still value in going for it anyway.
After learning as a group in a classroom environment for 2 days, the challenge of a post-class assessment will encourage participants to continue learning Scrum on their own. They will be much more likely to review the materials, do more research, and attempt some practice tests; as opposed to a non-certified class where they close their books after class and are less likely to ever open them again.
So regardless of what people think about the value of a Scrum certification, we’ve noticed that those that take on the challenge of certification tend to have a minimum knowledge competency level and speak in a more consistent language. That’s worth something.
