The problem with IT licensing as it currently exists is that it is pretty much all vendor-generated and product-related. IT licensing that pertains specifically to certain technologies is broken. It produces marketing drones and vendor billboards in the form of supposed IT "professionals". That's not to say that, for instance, all Microsoft-certified IT professionals are useless. I'm a card-carrying member of the Evil Empire myself, in that regard. This only means that the certifications themselves are nearly useless, generally speaking. If you have any ability to correctly assess the consequences of your actions, you'll realize that looking for certifications in someone's resume is gambling that this person actually learned something useful as an incidental effect of whatever process he or she used to cram for the certification exams.
If IT licensing is to become widely useful and to begin to measure relevant characteristics of IT professionals, it must become more principles-based. Technology and vendor dependency in licensing must be foregone in favor of testing for understanding of general principles. Technology- and vendor-based licensing cannot even ensure that it will accurately measure anyone's ability to correctly use the technologies and vendor products that are represented, let alone any real understanding of the principles and requirements of the job at hand.
A principles-based approach to certification, on the other hand, can more easily be made relevant. True, employers will still be forced to find some way of determining the familiarity of a given applicant with the technologies the employer uses. That can, however, easily be covered by entry exams at the employing company level, and any company that is not willing to simply take the applicant's word for his or her experience should currently be employing such tactics anyway, since the vendor-sponsored certifications that currently exist tend to be shaky at best in their usefulness.
While I have not yet pursued (or had the time to pursue) CompTIA certifications aside from the A+ I've had for several years, the above is much of the reasoning behind my preference, in principle, for CompTIA tests and their vendor-independent cousins for certification. CISSP and Security+ certifications strike me as significantly more useful for determining fitness of a given IT professional to an IT job than a Cisco- or Microsoft-related certification, for isntance. Unfortunately, while the CISSP certification seems to be in some demand at present, the industry seems to be continuing in its trend of relying ever-more heavily on vendor certs.
Hmm. With a little more research and editing, this would have been a great front-page article for TechRepublic. Too bad they don't return emails.
