I'm doing pretty much what boc's doing, from a slightly different setup. But the root cause is the same - a fundamental lack of expectations for kids with SN, at every level of the SEN industry.
I'm not saying that every SN professional acts like this - far from it. But my experience is that some professionals on the front lines do act like this - and every single professional I've encountered who doesn't work on the front line has had appallingly low expectations of the children they draw a salary to help.
DS1 scores in 98th-99th percentile in various non-verbal reasoning assessments, 1st percentile for expressive / receptive language. He is a frighteningly gifted thinker whose development is crippled by several serious dx'd language disorders. With the right support and expectations at the right time, he could do very well in life.
But he hasn't had that - his primary school had the right expectations, but couldn't offer the right support. As for his secondary school....
We recently went to tribunal to secure a place for DS1 in an indi SS with a proven ability to enable children with severe language disorders to achieve 5 A-C grade GCSEs. We asked for evidence of outcomes from the school. They provided it - in spades. We felt this was a reasonable thing to aim for - outcomes regarded as the minimum acceptable standard for a school to achieve with NT pupils, even though DS1 is cognitively more capable than this.
The tribunal hearing didn't go well for us. In part, it was because we didn't know which school the LA were planning to name until a few minutes before the hearing started. But mostly, it was because the panel found our expectations for DS1's education to have outcomes to be outrageous. The panel found our request for the minimum floor standard to be applied to DS1's objectives to be speculative. They found our request for DS1 to be educated by qualified professionals with a proven track record of success in helping kids like him to be unwarranted. And they dismissed DS1's high non-verbal ability as an irrelevant factor.
I was warned before the hearing that the panel might appear to be emotionless. Far from it - when we argued for meaningful outcomes to be written into Part 3, one of the panel members half-launched out of her seat and started to jab her finger at us. She was genuinely, personally outraged that someone might expect a statemented placement to have meaningful academic outcomes as the end result.
In the end, DS1 was placed in a maintained SS a lengthy daily commute away from our house. It's a fairly old-fashioned SS with embarrassingly low expectations of its kids. He left primary with a solid NC Level 5 in maths. He's spent most of the last year working alongside his peers at NC Level 2. And he still doesn't have the support he needs to manage his core language disorders.
If we'd have kept DS1 at that school, the end result would have been no friends, no GCSEs, and no functional language. Fuck that. I'm not waiting for my fight against the system to play itself out whilst his future dissolves away. So I'm moving, giving him a better shot - whilst keeping up the pressure on the unaccountable sociopathic carrots who have let him down so badly....
