The reason that all the documents / policies are requested is that as the learner is on a government funded programme the College is responsible for there safety, health and welfare. I have admit it does seem a tad excessive at very short notice although it is a standard request that a College or other training provider would make
I used to work for a training provider that delivered NVQ programmes in the construction industry, we had to explain to 6 foot 6 hard as nails construction workers that we were responsible for their safeguarding and if they felt that they were being bullied etc they should report it to us.
