According to the guidelines set out by the SpLD Assessment Standards Committee (SASC), we conduct an investigation into general cognitive ability, working memory, verbal memory, visual sequential memory, processing speed and rapid automatic naming, alongside the key characterise of dyscalculia including procedural, symbolic and verbal dyscalculic traits.  An in-depth analysis is carried out to evidence whether underlying difficulties in mathematics are related to dyscalculia, another specific learning difference, or another aspect of neurodivergence.
