Considering a career switch

I have been in the construction business for almost 40 years. I have worked almost constantly with computers since 1985. I am considering the pursuit of alternative vocations such as network administration or perhaps some other computer related service. Can you tell what certification programs are being offered that would help my marketability in this field?

Dear Bob:
Your best bet to get a sense of the landscape for IT certifications is to visit a Web site like or and look around to see what's available. At last count, I totted up over 700 certifications in this general subject area, from a bewildering mix of vendors, organizations, and consulting and training companies. Rather than try to fit the ocean into the oyster that is this e-mail reply, let me instead recommend you use the aforementioned sites to dive into that ocean and see what looks interesting to yourself.
Good luck!
