In trying to understand the value proposition for IT certification, employers and IT pros alike are always interested in finding good answers to the question posed in this blog post's title: "Why hire certified IT pros?"

A recent study from IDC (October 2015) entitled "The Business Value of IT Certification" provides some interesting and useful answers of interest to all parties.
As that inimitable and always sly soothsayer, Yogi Berra, once said: "It's like deja vu, all over again," when it comes to chart-topping IT skills and technical areas for 2016. There are some recurring themes here to be sure, but also some newer technologies that promise to take up residence on the short list of what's hot for next year.
Ever since I started writing about certification and related IT career development topics back in the mid-1990s, one perennial question I've been posed has been "Which is better: a college degree or IT certification(s)?" This is something I've written about repeatedly, but it's one of those questions that keeps coming up, particularly for cash-strapped youngsters trying to decide if their lmited funds should go to a degree, or some collection of specific IT certifications. For this blog post, I'll give a nod to an interesting and informative article over at GoCertify, and then revisit the issue yet one more time because of its enduring relevance to current and aspiring IT pros of all ages.
