Trends Slideshow: IT Certifications Still Offer an Edge

The quarterly Foote Partners IT Skills and Certifications Pay Index examines in depth how certain skills and certification can affect the pay of IT professionals. Unsurprisingly, the index found that most skills and certifications decreased in value last year.

But as a percentage of the "base salary" for IT professionals, most types of certifications gave recipients an edge in remuneration. Typically, IT certification holders made 7.46 percent more than average IT workers in the fourth quarter of 2009.

CIO Insight examines how much extra certain types of IT certifications have garnered professionals over the last three years. The percentages are all measured as additional value on top of the base IT salary, as determined by Foote Partners.
