Hi,
I cleared the ScrumManager® exam. Scrum is an empirical framework for agile practices. Easy to understand but difficult to implement in traditional organizations.
To be able to take the exam you must complete mandatory training. The organizations that provide this certification are:
http://www.scrum.org
http://www.scrumalliance.org
http://www.scrummanager.net This is for spanish speaking community.
The insights I got from this certification makes this worth the effort. I recommend this certification to potencial members of a scrum team. Not as heavy as PMP practices, it proves as well as useful, though.
Bye.
