She sounds like an amazing young woman. I'm very impressed. I'm so glad she has the opportunity to be educated where she wants to be.
That said, I'm not in favour of inclusion at all costs - an organisation I joined here some time ago, in the mistaken belief that it was there to help people with disabilities, actually has the brief to enforce inclusion in all situations, at all costs. Your girl would be fine with this - but kids like difficult child 3 simply can't handle mainstream, they do need special provisions and a separate environment.
If difficult child 3 could have you to himself, with him the only student, I have no doubt he'd do well - and he is bright and gifted in maths, he would do better than many other students given the same environment. But that would be at the expense of all the other students you could teach.
This girl sounds like she is where she wants to be, by her own choice. Having that choice is so important, I feel.
Does she know what she wants to do when she finally finishes school? She describes herself as "slow" - is this only referring to her physical speed?
A man I met back when I was heavily involved in charity fundraising, was the representative for The Spastic Centre. This man himself had CP, you could see it when he walked and it was definitely in his speech. I had to listen hard to understand him, but we all learnt quickly that when he spoke, it was in our interests to listen. A wise, witty, highly intelligent man - he became the treasurer for the fundraising foundation. It was a very high post indeed and he did the job brilliantly. A man with the typical speech difficulties of CP - had become a spokesperson and advocate. I just Googled his name - he's still very senior with the organisation.
Another CP public figure in Australia was a comedian who gave himself the name "Steady Eddie". He was NOT fond of the Spastic Centre. I remember one of his comedy routines centred on his childhood experience of having to go to a Special School and being told, "Now when you go out into the world you're just as good as everybody else, you are no different," and as he then said, "they then sent us on out into the world in a big bus with the words 'SPASTIC CENTRE' in huge letters all down the side."
Eddie's a bit of a rebel, but in his own way is also an advocate. He is also an actor and a real Aussie larrikin.
There is a "Steady Eddie" in Berkeley - not our bloke. Our Eddie lives in Queensland, still does stand-up comedy. I think I saw a glimpse of him streaking, on youtube. As it costs too much for us to download, I can't verify it was our bloke. But it is the sort of thing he's do.
The thing is, these people - Eddie, the charity foundation treasurer and your student - have all in my opinion showed drive, initiative, determination to live their lives each in their own ways, to find their purpose and live it to the full.
