You say lets not. I say, I cannot. One mans competence is another mans idiot. Can I do electrics? Yes. Am I deamed competent? to some, Yes. Do I do electrics? NO. Why? Because I’m not qualified. People will do what they want no matter what is said to them. I’m just doing my bit.
Legal definitions of competence vary according to the subject. I have an HNC in electronics. I've been building things for 50 years (since I was 12) but because I have not done a part P cert I am deemed 'incompetent'. However, someone who spends three weeks on a course is deemed competent. In a court of law facing charges of manslaughter it would be what was actually 'done' rather than a piece of paper that determined my guilt or innocence.
One of the things no longer taught, is the ability to use one's knowledge to determine a correct course of action / make decisions rather than blindly follow. IMO (it's never humble) too many incompetents run our world today and stop intelligent people questioning and progressing through the FUD factor.
