I mentioned http://www.scrum.org/ in my last post. I have recently completed the Professional Scrum Developer Trainer certification. This means that I can now train people for the Professional Scrum Developer program. This is backed by an assessment hosted on Scrum.org.
I think that this is a great program. For a long time teams have suffered from the "magic happens here" section of the scrum diagram. This course actually helps teams learn what really happens in the 2/3 week sprint that turns out potentially shippable software.
There is currently a .Net program available that uses VS2010 and TFS 2010 as its tooling. However there is a Java program coming soon.
Scrum Alliance are launching their own Certified Developer Program - see http://www.scrumalliance.org/pages/certified_scrum_developer
Scrum Alliance are also rumoured to be launching a Certified Developer program soon, so it will be interesting to compare...
