Professional Assessment for Numeracy and Mathematics Learning Difficulties.
Specialist Dyscalculia Assessments in Melbourne
Dyscalculia is a Specific Learning Disorder that affects the ability to understand, process, and work with numbers and mathematical concepts. Because numeracy difficulties can stem from several different causes, a formal assessment is the most reliable way to identify the nature and extent of the difficulty.
At Dyslexia & SLD Assessments Victoria, our dyscalculia assessments are conducted by Dr John Ryan, a psychologist with a PhD specifically researching dyslexia and related learning disorders. The result is a clear diagnosis, along with practical recommendations for support, modifications, and intervention.

What Our Dyscalculia Assessment Includes
- Numerical processing and number sense
- Arithmetic fluency and accuracy
- Mathematical reasoning and problem-solving
- Working memory as it relates to numerical tasks
- Processing speed for numerical information
- Spatial reasoning relevant to mathematics
- Understanding of mathematical concepts and procedures
Who Should Consider a Dyscalculia Assessment
An assessment may be worthwhile for children or adults who experience:
- Persistent difficulty with basic arithmetic despite repeated instruction
- Confusion with number sequences, telling time, or handling money
- Difficulty remembering mathematical procedures or formulae
- Avoidance of tasks that involve numbers
- A noticeable gap between strong verbal skills and significant maths difficulty (in children)
- Ongoing difficulty with numerical tasks throughout education and work (in adults)
These difficulties are common and well understood. A formal assessment identifies what’s behind them, which is the first step towards the right support.
The Assessment Process
- Initial enquiry and booking – email or call to arrange your assessment
- Pre-assessment information gathering – background information collected beforehand to inform the assessment
- Assessment session – conducted by a qualified specialist using standardised cognitive and educational instruments
- Scoring and analysis – results scored and analysed against standardised norms
- Written report – findings and practical recommendations provided in a comprehensive written report, normally within two weeks
- Follow-up consultation – results discussed with you, including options for ongoing support and modifications
Dyscalculia Testing for Adults
Dyscalculia is frequently undiagnosed in adults – many have experienced ongoing difficulty with numerical tasks throughout school and work without ever having it formally identified. An adult diagnosis can explain these longstanding difficulties and support access to workplace and study accommodations, such as extra time or the use of a calculator in exams.
The same rigorous, standardised assessment process applies regardless of age, giving adults the same quality of diagnosis and reporting as children.

Frequently Asked Questions
Dyscalculia is a Specific Learning Disorder affecting the ability to understand and work with numbers – it can involve difficulty with number sense, arithmetic, mathematical reasoning, and related skills like telling time or handling money. It occurs in both children and adults.
Depending on background and presenting issues, the assessment typically examines numerical processing, arithmetic fluency, mathematical reasoning, working memory, processing speed, and spatial reasoning as they relate to mathematics – using standardised cognitive and educational instruments, with background information gathered beforehand.
As with our other SLD assessments, you should allow approximately 3 to 4 hours of face-to-face assessment time.
Yes. Numeracy difficulties frequently persist into adulthood undiagnosed, and we assess adults using the same rigorous standard applied to all ages.
Yes. All findings and recommendations are provided in a comprehensive written report, normally completed within two weeks of the assessment.
Yes. Our reports are used to support applications for modifications and accommodations at schools, universities, and workplaces – such as extra time or the use of a calculator in exams.
Many people find some aspects of maths challenging at various points. Dyscalculia is different: it’s a persistent, identifiable difficulty affecting numerical understanding despite adequate instruction and effort, often accompanied by avoidance and a marked gap between numeracy and other skills. A formal assessment distinguishes between the two.
