Microsoft Certified Architect
I just came from the IASA Atlanta chapter meeting where the Microsoft Certified Architect (MCA) program was presented. Very interesting. The basic idea is having an architecture peer certification that doesn't get diluted. The process involves a presentation of a previous project and then go through hard questions by a panel of 4 fellow MCAs. They're going to look for evidence you have the skills to be an architect, and they want to know what decisions you made in the project and why. As I understood, is not only for Microsoft based technologies.
Seems very though, they're aiming professionals with at least 10 years of experience...
At least looks like it would be more meaningful than the Sun Certified Enterprise Architect (SCEA) in the sense that for an MCA you must be an architect already, and for the SCEA not (you will be architect after the exam).
