I passed the EIT exam, worked under professional engineers for four years, and obtained letters of recommendation from them, all so that I had the right to sit for the professional engineering exam. I then took that exam and passed it. I pay $200 per year to maintain my registered professional engineer status in my state. All this gives me the right to stamp legal documents as an engineer ... and be held legally accountable for designs that cause injury to others, either physical or financial. I wear a stainless steel ring on the little finger of my right hand that was given to me to remind me as I sign off on designs, that the safety of others is in my hands.<p>I am allowed to put on my business card, my website, and my consulting advertisements that I am an engineer. Theoretically, you are not, if you haven't done these things, and a case could be made that you should not be able to, just like you don't get to call yourself a doctor or a lawyer.<p>The term engineer has undergone serious deflation over the years, which is a shame. I don't see this trend suddenly reversing, so I don't lose sleep over it, but that doesn't mean we shouldn't feel a little regretful over it's demise.
