I have indeed known parents to seek a private Ed Psych assessment and for their child to be assessed as not having Dyslexia or any other learning difficulty. As one parent said the study was useful anyway because it enabled them to understand their child's ability and strengths and weaknesses even if there wasn't a specific problem. We have had a follow up test from a teacher assessor but the initial diagnosis came from an Ed Psych.
The study coolas refers to was widely misreported as undermining the existence of Dyslexia. It did no such thing as the Professor defended himself by highlighting in this thread www.mumsnet.com/Talk/guest_posts/a2044925-Guest-debate-Is-the-term-dyslexia-actually-useful what the study did was to query how Learning Difficulties are defined, it did not deny the existence of difficulties which require specific intervention and support. It's argument was that the focus should be on that intervention and support and parents should not have to seek a label, be it "dyslexia" or any other, to access that support.
coolas it always shocks me when I encounter attitudes like yours in teachers, as I have throughout my families (brother, nieces, nephews, daughters) school careers. Surely a teacher wants their pupils to achieve their potential? A diagnosis is only given when it is clear that a child is not achieving their potential because there is an issue, be it processing, working memory, attainment in literacy, numeracy, motor control, or all the other Specific Learning Difficulties that are tested for, some of which are widely perceived as coming under the labels of Dyslexia, Dyspraxis, dyscalculia etc. are you really saying that in your opinion unless these are severe enough to warrant a statement that there is no intervention or support that can be given? Really? That one teaching style fits all? That look / see works as a way of teaching all children to read? That rote learning of tables, spellings etc works for all? Really? That sticking with those teaching styles will enable every pupil regardless of their difficulties with working memory and processing will enable them to achieve their potential? That all the time I spent with my DD aged 6 with targeted intervention using Tried and proven techniques that gave my DD the phonic tools and added reinforcement to help with motor control skills was a complete waste of time? I may be expressing this at the extreme but surely it is about meeting every pupils needs in order to achieve their potential. Isn't it?
