I'm a chartered engineer - a REAL engineer. I worked hard for many years to achieve an accredited honours degree, and accredited masters degree and evidence of demonstrating the five groups of competencies. But everyone from the spanner-basher whose training went no further than "clockwise means tight" to the biuffoon who fixes our photocopiers also call themselves engineers. Machinists who turn and mill metal (which I also do in my own workshoip, as a hobby) call themselves engineers. In the colonies even TRAIN DRIVERS call themselves engineers. Never mind those medical practitioners who've never done any academic research in their lives but still claim the title "Doctor".
I once got a job because the only point on which to choose between me and the other candidate was that I had CEng, and the technical director who made the hiring decision had one too. So
some people know what it means.
