I've been looking at a few of the Agile certifications, and was recommended APMG's
Agile Project Management certification. It is based on DSDM's framework (which I don't know a lot about) and it seems to have a little more rigour than the Scrum Master certification, and a bit less "cludgy than Prince2 Agile" and more accessible than PMI Agile certified Practitioner. Plus, it has a self study option

But does anyone know how these compare? Or have a recommendation for other good quality Agile methodologies/frameworks with certifications?
