I don't 'take sides' and, when I used to post more on the TES forums, would do exactly the same as I have here.
The reality is that sometimes, teachers are crap and think they know more than they do. SEN training is diabolical and is only now improving. I had about 2 hours' training on SN and only learned more about it on a child-by-child basis. Now I'm more expert but many colleagues aren't and it's not lack of interest, but lack of training that's at fault. Also, there are some who just aren't interested and don't believe that 'these children' should be educated by them. Then there are some that believe the LA line about not doing Statements/ illegal criteria etc.
However, there are also some parents who get it wrong - never usually out of bad intentions, but still not ideal. Another SN forum I used to go on had lots of evangelical posters who would tell any newbies that they had to get their child Statemented. Sometimes, it just wasn't necessary i.e. the parents were saying that their child was dx'd but had no major problems at school or home, had friends and was progressing academically. Yet these posters would convince them that they'd be failing their child without a Statement. Some parents independently decide that their child should have one because it gives their child a better chance.I've met parents who want Statements for their children because their reading/ spelling ages fall just below the fiftieth centile...it's very difficult sometimes to convince parents that you're not saying no to no help because you're being stingy, but because there is no need.
Statements aren't always necessary, as in the example above. And with the TES post, my impression was that the SENCO meant the child didn't meet the criteria because she was progressing fine and they could meet her needs in the school. That is the only criteria for a Statement, after all: can the school meet her needs from their own resources? If the school feels it can, then the child doesn't meet criteria for a Statement. Now, maybe the SENCO is wrong and should listen to the SALT but I would expect that the teacher who is with the child every day would probably have some idea about the child's progress too. Not all SALTs know their stuff And even if the SENCO is wrong, not everything that a teacher does wrong is malicious, just the same as for any parent.
To be honest, my experience as a parent is enough to convince me that parents of SN children probably have bad enough experiences to feel negative about most teachers and schools J has had some amazing teachers but both SENCOs have been appalling and known less about the system than I have and we've come across some shocking teachers in both schools too, just luckily not teaching J full-time. I guess I just feel strongly that the way forward is not for all teachers to dismiss all parents or vice versa.
