In the past 7 years, I've met many people who have taken and passed one or moreDB2 certification exam. I like to chat with people, so I usually ask them to tell me if they see benefits to passing an exam. I also meet with many people who are reluctant to take an exam and must convince them of the benefits. I'll put a few of my findings in this post, but I hope that I hear from people if they agree or disagree!
People who are reluctant to take a certification exam are usually reluctant due to fear. Fear of failure, fear of taking a test, fear of having others learn their scores, or fear of being judged or ranked. I totally understand these fears! The first thing I want to stress about certification exams is YOUR SCORE IS CONFIDENTIAL TO YOU. Sure the score is captured by a computer system and is sent to IBM to be stored in a DB2 database, but we are governed by very strict privacy laws that prevent any of this information to be given to anyone except for the candidate who is taking the exam.
