Disorder of written expression

Disorder of written expression is a type of learning disability in which a person’s writing ability falls substantially below normally expected range based on the individual’s age, educational background, and measured intelligence. Poor writing skills must interfere significantly with academic progress or daily activities that involves written expression (spelling, grammar, handwriting, punctuation, word usage, etc.). This disorder is also generally concurrent with disorders of reading and/or mathematics, as well as disorders related to behavior. Since it is so often associated with other learning disorders and mental problems, it is uncertain whether it can appear by itself. The prevalence of disorder of written expression is estimated to be of a similar frequency to other learning disorders, between 3 - 5%. A diagnosis can be made based on results of several assessments.
