Paul- if your son/daughter doesn’t mind training for 2-3years they can get full gold card requirements for JIB without doing short courses.
A lot of colleges offer 2365 level 2 and 3 as evening courses (two evenings a week)- one year for level 2 (less than ÂŁ2000 in most places and paid in instalments over the year), another year for level 3 (paid for by government no matter how old you are or what previous qualifications you have, but only if done at a college and not a training centre).
They can then do the NVQ Level 3 in the third year- or alongside the level 3 which is what I am doing now. NVQ is about ÂŁ1000 and you need to do the AM2 which is about ÂŁ400-500.
Plus you can be working in the industry throughout as a mate/improver somewhere to gain experience and earn while you learn!
