For those of you who don't already know, we've re-created my print book entitled "IT Certification Success" (which appeared in 5 paper editions between 1999 and 2005) as an e-book right here at PITC.

One of its most popular features is called "Ranking Certifications" wherein we apply a series of metrics to compare over 100 IT certifications by level of difficulty, time required for completion, number of exams involved, out of pocket cost, background and experience required, and average pay for certifications holders. We've just finished updating this massive research effort and for today's blog, I want to report on what changed since this ranking was last updated in 2014.
