Your in a tight spot right now but it's fuel for tomorrow's fire. ( at the expenses of your child of course).
I agree with senvet. At work I am always told "tell people what they want to hear" Ie suck up to my boss ;0)
So I agree, say your sorry, sad, disappointed it's come to this ( through your teeth) ask what they have tried, ask why they can't meet needs, pick out the best bits of why needs can't be met, file it away mentally.
In my county every parent I personally know has got into indi as without attending a appeal.
Ms can't meet needs, ok, but they said the needs was too complex, to severe, to whatever. Then the parents had a child to traumatised by school, classes to big, appealed, all dropped by la before hearing.
I know that's just poo. It's wrong. But it builds a case. Of course it too, is never that simple.
My la either fight to the death or roll over spectacularly. Rolling over always happens after placement failure. You truely do need to fail before your helped here.
Once my appeals done and ds3 is placed I might name and shame
