The headline, extracted from a popular song lyric*, uses the double-negative "don't need no", quite intentionally - to help emphasize a point. Whatever the song writer meant I'll leave to others to decipher, but for my purposes hopefully it will get attention.
* The lyric "We don't need no education" is extracted from Pink Floyd's "Another Brick in the Wall" song, written by bass guitarist Roger Waters.
As an introduction, I hope the heading helps to break the ice on what might seem to be an otherwise tedious sounding subject. In this blog, I'm asking how do we assess competence? Specifically, I'm thinking of the competence of people who, on a daily basis, live with high hazard processes, machinery, or who work on projects involving safety systems. Education is part of the picture, but certainly not the full story.
