Hi,
My advice would be to speak to your original College/Training Provider, with a view to completing NVQ Level II.
As for your Portfolio of Evidence, the jobs (three jobs-carried out twice + H & S). These must be carried out at the addresses of the site visits.
All current Portfolios are now electronic with info uploaded by you and your Assessor. So dates would all have to match.
Sorry but it does seem you were not made aware of the facts originally !!
Maybe your original Training Provider can see a way forward, given their lack of clarity?
