Its a legal minumum qualification you need to teach adults of any official description in the UK. You can still teach privatly etc.
My idea is I may be able to get more home tuition work if I said I was a qualified adult teacher on my website, qualilfied is stretching it a bit though its a ten week course not a degree (although I do have a degree).
I was thinking of teaching key skills and basic IT use in colleges, or even more advanced stuff such as basic programming etc.
As most adult lecturers work very part time, sometimes just 3-4 hours a week it would fit perfectly with my current job. I want to buy a house in the next few years so this is important.
Sorry to off topic, but it does sort fit in the subject, there is often better things you can with your time than learning a skill like soldering on something which will become throw away anyway.
