I see your point but I'm sick and tired of the 'accentuate the positive' line - it's like some kind of Stockholm syndrome, if we work with them, and encourage them they'll get better by osmosis.
They won't. Why? Because it is about money and careers and self-perpetuating bureaucracies that only give a crap about how parents think in so far as it reflects on their own auditing criteria.
I'm tired of big charities buying into this as it helps justify their own existence (or provides funding). We hear enough about evaluations that tell LAs how great their work is, or their SLT service is, or Bills before Parliament supported by charities tied to their success or parental advocates groups telling us to look at good practice when they are too wimpy to start shouting about bad practice.
My point is - if you don't know what 'good practice' is perhaps, as you guys have pointed out yourselves, it's because you don't realise that the services your child is being offered are crap.
But if you know what the law says, you realise how crap things are because LAs ROUTINELY act unlawfully.
So, you could approach it two ways: accentuate the positive and start a campaign talking about how good things can be when they are actually almost universally, shit, in the hope that (a) parents might self-refer and question their own provision and (b) other LAs will see the error of their ways.
But, seriously, what is the point of that when we know that the reality is, if you are looking for examples of 'good practice', they will be individual based - indeed, point is proven by the limited examples of 'good practice' on the SN Jungle website. And, actually, I defy anyone to find an example of an LA which doesn't routinely pursue unlawful SEN policies or which measures the outcomes of its interventions or which demonstrates a clear understanding of the Equality Act etc etc. ?
Or you can at least let parents tell the truth about their experiences in the hope that someone might pay attention and that, in the meantime, parents will see they are not alone.
If it looks like shit, and smells like shit, it's probably shit.
So why concentrate on the occasional petal of apple blossom?
