A good start for understanding Agile Software Development would be http://www.agilemanifesto.org/ - inclusively linked content. Note, though, that "agile" has become quite a buzzword, and that not everyone nowadays is using it in this "original" sense.
The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
Well, there is also a DSDM certification. Scrum is much more wide spread, though, and I've heard people say that DSDM isn't exactly the most Agile approach you could use. Don't know enough about it to comment, though.
