I have recently done these qualifications... You need level 3 in hairdressing then do an assessors course which is now TAQA previously a1 - I did this in 12 weeks but all work is done at home and sent via email so you need to be really self motivated as Its a lot to do in a short space of time and there is a huge amount of evidence to gather. I only actually attended college once for 4 hours, Only catch is you have to have assessing hours, I volunteered at my local college and I was lucky enough to be employed by them as a lecturer by the end of it. You then have to do cert ed which is 2 years, my advice would be to try and get employed somewhere and let them put you through that as I think it's around £3000 per year minimum! Hope this helps!
