Chris Singleton's response to my article is extraordinary (Letters, September 24). He reduces my legitimate concern about the misuse of psychometric assessments to a personal pathological problem when the evidence suggests they are not "objective".
He also asserts that I want to restrict assessments to a "select club", which is a more accurate description of the inner circle of the working group that excluded me, despite the fact that I represent hundreds of teachers trained to diagnose dyslexia in the post-16 education sector.
While the definitions and diagnosis of dyslexia remain contentious, it is vital that different opinions are heard, and that the quality assurance systems in place for dyslexia training are evaluated and recognised rather than replaced by a single ideological view, more bureaucracy and policing procedures.
