Are there any prerequisites before taking the exam, for example certain years of experience in working with ARM based processor hardware/ software? I feel, mandating a year or a couple of years of experience in working with ARM based processor for taking the exam makes practical sense. But, that might create "chicken and egg" situation for the engineers fresh from college.
This may be the first processor-based certification but I see calls for certification come and go periodically. I have yet to see one which was worth the effort for someone doing embedded software and I expect this one to be no different. Contrary to Kris's assertion, I don't expect it become a requirement; I've never worked with an ARM core and don't expect to in the foreseeable future.
