Hardhead_7 writes "Our recent discussion about how much your degree is worth got me thinking. I've been working in the IT field for several years now, but I don't have anything to my name other than an A+ certificate and vendor specific training (e.g., Dell certified). Now I'm looking to move up in the IT field, and I want some stuff on my resume to demonstrate to future employers that I know what I'm doing, enough that I can get in the door for an interview. So my question to Slashdot is this: What certifications are the most valuable and sought-after? What will impress potential employers and be most likely to help land a decent job for someone who doesn't have a degree, but knows how to troubleshoot and can do a bit of programming if needed?"
