As part of the collection of articles right here on this very site that are collectively known as Ed Tittel's IT Certification success, there's a two-part item entitled "Ranking Certifications," where Part 1 explains the methods used to do the ranking, and Part 2 uses those methods to rate and rank around 100 of the leading IT certifications currently available in today's marketplace. Those two items have just received an annual update, and thus, may be worth checking out again (or for the first time, if you haven't ready them already).
Not much has changed in the methodology part, though it is worth re-reading to refresh yourself on the various ranking criteria used, and how they get assigned numerical values to calculate raking values. The 2012 rankings cover 85 different credentials from a total of 28 different sponsoring organizations (for vendor-neutral items) or companies (from vendor-specific ones).
Here are the top 5 items that appear in that list, to give you some idea of what garnered the highest ranking values:
Next in line come the Microsoft Certified Master (MCM) credential, Check Point Certified Master Architect (CCMA), Oracle Certified Professional (OCP), Citrix Certified Instructor (CCI), and the EC-Council's Computer Hacking Forensic Investigator (CHFI) credentials. Check out Part1 and Part 2 of Ranking Certifications (2012 Edition) for all the details. In case you're interested, here's the top-level link to "Ed Tittel's IT Certification Success," too.
