Though it is true that CompTIA has been around in some form since 1982, They were hardly relevant until the mid to late 90s as an organization. During the late 1980s and early 1990's Novell Netware was the defacto certification to have in the PC industry and it cost plenty to get study materials, attend classes, and take the exam.
By the time these certifications were available to me around 1995 at Sprint, there was a growing debate on where certifications, and even networking technology was going. Novell was loosing ground to Banyan Vines and others and by 1997 TCP/IP was more fully integrated into Windows 95. This made Netware and Banyan nearly obsolete as well as their certifications.
It was about this time that Sprint's Atlanta IT staff was going nuts paying as much as $700 for DVDs and books to cram for the CompTIA A+ exam as Home Depot was purportedly hiring all the A+ certified techs they could get their hands on. With stock options and high pay to chum the waters, the IT staff was abuzz about A+.
Honestly, I was already largely doing their job for them in our call center as they didn't know their head from a hole in the ground in how we were set up and our requirements (a previous head tech who could probably still teach me stuff had left the company). So I had little confidence in a certification many of them could pass.
However, at this time I was considering spending the money for getting certified that I had the option for Sprint to send me to, and pay for, Genesys in San Francisco to become a Certified Genesys Engineer. A qualified Genesys engineer could make significant more money in the industry than A+, so it was a no brainer. It wasn't long after I had most of my Genesys certifications that I was recruited by E-Invest Group (a dot com that busted with the rest), then six months later was interviewing with BellSouth, Verizon, and the ultimate choice IBM.
Since I've opened Panther Computers, I've considered taking the test to allay any naysayers, but I feel that experience and results matter more than some pathetic certification that means little. Worse still, CompTIA, in order to make more money (so much for non-profit) has a requirement to retest every three years. I'll troubleshoot against any A+ and beat many if not most of them while multi-tasking on several other PCs at once.
About the time you see me go for A+ certification, will likely be a time that means I'm looking for a job. Even then, I'd be more likely to renew my Genesys Certifications first. You can see more about my thoughts on A+ in the article Computer Shops and The Licensed and Bonded Lie.
