'He has been separated from his best friend and three of the four others in his 'gang'. '
right - so he hasn't actually been sep from all of his friends then? the school have just split up a 5 boy 'gang', probably for very good reasons, to a 2/3 split between the classes. probably to allow that strong friendship group to have less dominance in one class? so the odd one boy moving over the summer (whose parents must have had a genuine reason to discuss with HT - sn?) still kept it at a 2/3 split for the original 'gang', so each of them had at least one friend from the original friendship group in the class?
so if your boy gets moved, you are leaving one of the original gang in a class (genuinely) with no friends from the original 'gang'?
or have i misread that?
i'd say you have no chance at all. and with 3 dcs, we've had no frinds years, pg teacher years, nqt years, nqt who has nervous breakdown and goes on long term sick after 6 weeks years (filled by supply teachers, and after 4 months, a job share
) and, oh, a class where there were 25 ESL students who spoke not a word of english, and a few other years where i hung my head in my heads and expected the worst.
but they were all fine. and ther's no way i'd let any of my kids think that i dictated their classes. a quick shrug and an 'i'm sure it will be fine darling' seem to suffice.
i'm not even going to get inot the mat leave/ promotion thing aspect. tosh. a child with dx sn and support in place would be able to use this as an argument. not an nt kid who wants to be with his mates.
