I started testing again after about 12 years,2 years ago.I had no qualifications but i had taken the NT test when i first started testing, but it was up to me to provide the certificate that i had passed. I had to do the 2 day course, think it's three days now with computerisation, so can he provide the proof of passing NT test! I did the AE course and now the proud owner of an MOT station.All pretty straight forward really, as in the other post about the NT test quite easy, but can be caught out.
