Today I received my Scrum Trainer logo from Scrum.org. I can now deliver the 2 day advanced class 'Scrum In Depth.' This is a great course that really provides a lot of practical guidance for Scrum Masters.
More details on the course can be found here http://www.scrum.org/storage/Scrum%20in%20Depth.pdf#view=fit and here http://www.scrum.org/scrumindepth/
I really like this course as it provides standard material for students. So regardless of who takes the course or where it is delivered the content is the same - and the content was written by Ken Schwaber - who better to learn from!
Scrum.org have also launched the Professsional Scrum Master assessment, see http://www.scrum.org/scrummaster/. Currently there are two levels:-
Professional Scrum Master I (Beginner) and Professional Scrum Master II (Intermediate.) The Scrum In Depth course helps to prepare people for the Professional Scrum Master II program. The great thing about these certifications is that they are backed by assessment. So students actually have to pass a test. For the PSM II this includes essay style questions as well as mulitple choice (and its really pretty tough!!)
Feel free to get in touch if you would like any more details on this, or any types of training.
