A Specific Learning Disorder (SLD) is a diagnosis that is used to describe a person who is able to learn and achieve academically, but their knowledge in specific areas is disorganised or disordered. For example, a helpful way to think of dyslexia is dys- “disorganised or difficult” lexia- “word or lexicon” * lexicon = dictionary Inside your head. Typically, a person’s internal dictionary is ordered or organised (like a dictionary is organised alphabetically), making it easy and efficient to find and use words. A person with a disorganised dictionary has difficulties finding the words they want to use. This makes reading and spelling frustrating and fatiguing. Similarly, dyscalculia is like having a number line in your head that’s in the wrong order, or not straight.

There Are 5 Different Specific Learning Disorders

Currently, there are five types of specific learning disorders listed in the Diagnostic and Statistical Manual – Fifth Edition (DSM-5). The most well-known of these is dyslexia. Dyslexia and other learning disorders can affect people in many ways, however there is a set of symptoms that are characteristic of each and must be present for a diagnosis to be considered. These include:

  • Dyslexia– difficulties with word reading, spelling and fluent reading.
  • Dyscalculia– difficulties with number sense and understanding value, learning and memorising maths facts and completing calculations fluently.
  • SLD with impairment in reading– difficulties with word reading, reading comprehension and fluent reading.
  • SLD with impairment in mathematics– difficulties learning and memorising math facts, limited number sense and understanding of value, difficulties with problem solving and calculating fluently.
  • SLD with impairment in writing– difficulties with spelling, limited understanding and use of correct grammar and punctuation and limited clarity and organisation when writing.

How is a Diagnosis Made?

There are a number of other considerations that must be met before a diagnosis is given by an educational psychologist, but the patterns of difficulty that we’ve listed are a good place for other educational professionals to start when questioning whether someone has a specific learning disorder. Knowledge of these patterns of difficulty can also assist with tailoring intervention. More about that in another post.
