Maths-related Difficulties and Dyscalculia

Many children (and adults) experience maths-related difficulties. Unexpected maths difficulties can be explained by various factors, including gaps in maths education (including the disruption to education during the COVID pandemic), maths-related anxiety or inappropriate teaching methods.


​Difficulties with cognition and processing associated with dyslexia, e.g. language skills, visual-spatial skills, working memory and processing speed, can also impact maths learning; therefore, many individuals with dyslexia also experience difficulties with maths.


Dyscalculia is a specific and persistent difficulty in understanding numbers which can lead to a diverse range of difficulties with mathematics. It can occur on its own or can co-occur with other SpLD, such as dyslexia.

Screening Assessment for Dyscalculia


This is a shorter assessment for children aged 9-14. It consists of an online dyscalculia screener and tests that assess maths attainment and number sense.

Full Diagnostic Assessment for Dyscalculia

An assessment for Dyscalculia or Specific Learning Difficulty impacting maths for children consists of a full range of tasks to assess verbal and non-verbal abilities, cognitive processing, maths skills, maths computation and a short online screener to investigate the concept of number. Some aspects of literacy (reading, spelling) will also be assessed; the specifics will vary depending on the individual. 


The assessment takes 3-4 hours. Following the assessment, a full detailed confidential report is completed and emailed within 15 working days.

The report will include an overview which summarises the child's cognitive profile, their strengths and the impact any cognitive difficulties may have on their learning. It will include a diagnosis of dyscalculia if this is supported by the assessment. The remainder of the report includes a summary of the background information provided by home and school, an interpretation of test results and observations and detailed recommendations for support.

Joint Dyslexia and Dyscalculia Assessment

A joint Dyslexia and Dyscalculia assessment can be completed over 2 sessions if there is also a need to focus on literacy skills.
