This is not representative of the CIA certification.  This is the Pearson Vue test center that you want to with what sounds like a very bizarre and unnecessary security measure. 

I have sat for and passed both the first and second parts of the CIA exam within the last two months and have had nothing but a positive experience.  I also tested at the same center 2 months prior to that for my GMAT.  They have asked me if I have anything in my pockets, asked me to put anything from my pockets in a locker, and given me the key to that locker.  Other than that, they took my picture and had me do a quick fingerprint scan. 

I test in North Carolina at the Charlotte Pearson Vue center.  I am sorry for the experience that you had.  It is certainly completely ridiculous.  I would send an e-mail to one of the higherups at Pearson Vue letting them know that you don't appreciate what was done.  Do you have the option of any other nearby Pearson Vue centers?  You may not, my next closest was an hour further.  The current center that I test at is 20 minutes from my house.
