Hi Mitchellmm, when there are certifications for shops I usually wait until I see a shop I am interested in and then take the quiz. Many of the long lists of certifications are for jobs that do not exist where I live. I have found only a few companies where they do not show you the job until you are certified and if that is the case they might mention that fact. I do a shop for them that requires re certification every few rounds but I still see the job without having the new credentials and if I apply for it I get the chance to certify right then and there.
