I've designed a RAN test for reading difficulties evaluation. In short, frequently reading difficulties (dyslexia) are diagnosed too late, at 2nd or 3rd course at Primary School, when there's a gap of two courses between Chronological age (real age) and reading age (child at 3rd whose reading speed-accuracy are two courses below his age)
Several studies have proven that before acquire literacy skills, early detection can be achieved with a RAN test (that measures the time that a child lasts to name a presented stimuli on a grid: object, colours, letters or digits) guided by an examiner; greater time may predict reading difficulties in the future; the importance on that is that reading difficulties can be trained during the time between the detection and the diagnose so reading difficulties can be reduced during these years of intervention.
