Assessments for Dyscalculia

Dyscalculia is a specific learning difficulty that affects the individual's ability to acquire arithmetical skills. It can manifest itself as a person's inability to understand basic number concepts and/or number relationships, recognise symbols, and comprehend quantitative and spatial information.

Many people liken the effects of dyscalculia with numbers to that of dyslexia with words, and while there are many characteristics that overlap, there is no proven link between the two.

Research suggests that, like many SpLDs, dyscalculia has varying levels of severity and can affect different areas of mathematical calculations.

While dyscalculia is less well-researched that dyslexia, it is nevertheless a recognized specific learning difficulty that may affect individuals across a broad spectrum of general ability.

Dyscalculia is defined by reference to an authoritative source such as The Diagnostic and Statistical Manual of Mental Disorders (DSM). In the Fifth Edition of this manual dyscalculia is defined as a difficulty with the production or comprehension of quantities, numerical symbols, or basic arithmetic operations that are not consistent with the person's chronological age, educational opportunities, or intellectual abilities.

Multiple sources of information are to be used to assess numerical, arithmetic, and arithmetic-related abilities, one of which must be an individually administered, culturally appropriate, and psychometrically sound standardized measure of these skills.

Assessing for Dyscalculia

We have many years experience assessing children and adults with the specific learning difficulty of dyscalculia. A range of tests will be used

  • The Wechsler Intelligence Scale for Children – Fourth Edition (WISC IV
  • The Wechsler Adult Intelligence Scale – Fourth Edition (WAIS-IV)
  • The British Ability Scales – Second Edition (BAS-II)
  • The Wechsler Individual Achievement Test –Second Edition (WIAT-II)

Prior to carrying out the assessment you will be asked for background information. In the case of a child this will involve school and any other professional reports. You will also be asked to complete a pre-assessment questionnaire designed to elicit background information.

Recommendations will be made for support in school or the workplace.
