Learning disabilities applies to difficulties in reading, mathematics, and written language. Although children with learning disabilities can have difficulty with spoken language and language comprehension, most of the research revolves around the ability to read and understand written information. For further information about oral communication one should look at material in speech and language, which is beyond the scope of this entry.

Learning difficulties can be present in reading (phonics, comprehension), mathematics (calculation, reasoning), language (receptive, expressive), and written expression. Learning disabilities are assumed to be due to central nervous system dys-function (National Joint Committee for Learning Disabilities [NJCLD] 1991) and reflect a discrepancy between ability and achievement.
