What is Dyslexia?
Many parents and teachers believe that dyslexia is a type of word blindness that is often linked to letter reversals. There is much more to dyslexia than this, and it can affect many areas of spoken and written language.
According to the Delphi definition of dyslexia (2024), dyslexia is a learning difficulty that affects reading and spelling, often showing up as slow or inaccurate reading and poor spelling skills compared to others of the same age. It varies in severity and can impact other areas like maths, reading comprehension, or learning new languages. Dyslexia is influenced by both genetic factors and environmental influences and usually involves problems with phonological processing such as recognizing and remembering sounds in words. However, other factors like working memory, processing speed, and visual word recognition also play a role. It commonly occurs alongside other developmental challenges like ADHD, dyscalculia, language disorders, or coordination difficulties.

What is Dyscalculia?
The Specific Learning Difficulty Assessment Standards Committee (SASC) has developed a new definition of a Specific Learning Difficulty in Mathematics (2025).
Dyscalculia is a learning difficulty that makes it hard to understand numbers and maths. People with dyscalculia will struggle with ‘number sense’ in tasks like naming, comparing, or ordering numbers, estimating amounts, and understanding place value. These challenges can be caused by problems with how the brain processes numbers, but other issues, like trouble with language, memory, attention, or visual-spatial skills, can also make learning maths difficult. Not everyone with maths difficulties has dyscalculia, but the impact can be just as strong. Maths anxiety commonly co-occurs with a Specific Learning Difficulty in mathematics but is not an indicator in itself.
A Specific Learning Difficulty in mathematics frequently co-occurs with one or more of the following: attention deficit hyperactivity disorder (ADHD), dyslexia, developmental language disorder (DLD) and developmental coordination disorder (DCD).

What is Dysgraphia?
Dysgraphia is a learning disability that makes writing hard for children. It affects how clearly they write, how they spell, and how they organize their thoughts on paper. Some children are born with it, while others may develop it later due to injury or illness.
