I am a DBA by responsibility but not by job title. How does someone like me "prove" that they know what they say they do without certifications? They may not be worth much but they are better than a resume where there you can say you have any skill you want and its nearly impossible to check.

Maybe PASS or some other user organization should start offering some sort of certifications. Perhaps based on lab tests of some sort that could be peer graded by a group of people so we lower the amount of personal bias in grading.
