What's important to understand is that certifications can be used in different ways by different industries. Some use them as a minimum requirement for performing certain jobs. In such a case, listing certifications is valuable not because it says you are any good at your job, but because it shows simply that you meet the minimum requirements to be legally employed in your profession. The other way they are used is as a marker of expertise. This is almost always misguided. Advertising one's certification status where none is required conveys a sense of insecurity, need for social approval, and overly strong attachment to formal procedures. That does not mean you cannot learn something from a certification course - by all means! But true experts are always judged by their results, not by their certs.
