Dear Donuel, state schools in the UK are not without their faults & inconsistencies, but based on my own experience, a 180 page folder of 'concerns' would have almost certainly been included in an application for 'Statementing'...a process, once triggered, that provides extra, specialised help & support for the student in question. There are cost implications, so Statementing is a rigorous & often protracted process, but once in place, it can transform that student's life. I was profoundly angered to read that Dean was punished in such an insidious way, rather than receiving the help & understanding he needed. To use your words, dignity & respect were conspicuous by their absence.
             Frustrated by my inability to help in any concrete way, I nevertheless offer my experience & training unreservedly,
                                                         Nigel.
