Hi there,
I mentor Derby Uni students. Your placements follow the hub and spoke placement format. You will be allocated a specific area for your hub placement. This means that you will be mainly based in that area for the year but split into 3 blocks. I believe it is something like 4 weeks for the first block, 5 weeks for the second block and 7 weeks for the 3rd block. In between you will have spoke placements which I think are between 2-4 weeks long. Your first and second year will be structured like this and so will your third until you hit management placement, then you will be allocated a new area.
I hope this helps.
