So two questions...
1)
Qualification wise or certification.. which are mickey mouse?, and which are bonafide credible?
I belive city and guilds are a good examining body, particulary with practical engineering qualifications.. but also thare are many different institutions such as the ICL (institute of certified locksmiths) whom charge membership fee's.
(not trying to answer my own question, just waffling/elaborating)
Also..
2)
ICL (as an example) require a police check- my only offence being arrested for Breach of the Peace at an environmental protest

How squeeky clean does your record have to be for membership of a worthwhile institute/guild?
Cheers
