Developmental Language Disorder (DLD)

What is Developmental Language Disorder (DLD)?

  • Children and young people with DLD have difficulties understanding spoken language and/or using it to express themselves.
  • A child or young person may be described as having DLD when their language difficulties:
    • make everyday life and learning at nursery or school much harder
    • continue even after getting extra help at home and in nursery or school
    • are likely to be long term.
  • There is no known cause of DLD. However, we know that it is not caused by:
    • parenting style
    • being bilingual
    • emotional difficulties
    • being autistic
    • other medical conditions, such as hearing loss or severe learning difficulties.
  • Children and young people with DLD may have other conditions such as ADHD (attention deficit hyperactivity disorder) or Dyslexia.
  • DLD affects around two children in every classroom.

How does a child with DLD act at school?

Every child and young person with DLD is different. Children's needs and behaviours will also change as they get older.

  • These are some of the things you may see in a child or young person with DLD:
    • Difficulties focussing in class (especially when listening to lots of spoken information).
    • Finding it hard to follow instructions or understand questions.
    • They might need more time to make sense of spoken or written information.
    • Limited understanding and use of words.
    • They may find it hard to express themselves, including finding the right words and putting their ideas in order.
    • Having trouble getting along with others, including joining in, working or playing together.
    • Having difficulties understanding things like jokes, puns, slang, or words that do not mean exactly what they say.
    • Having difficulties with reading and writing.
  • Some children and young people who have behaviour or emotional problems may also have DLD without anyone knowing.
  • Language and communication difficulties should be considered for these children.

What can I do to support them?

  • Children and young people with DLD do not learn language as fast or as easily as others. They need extra help and other ways to learn.
  • In a communication-friendly place, children and young people with DLD can do well in school.
  • Adults can help children and young people by changing how they talk and communicate. The next few points can help with this:
    • Showing information with pictures, symbols, photos, or videos.
    • Creating ways to learn by doing things and giving them the experience of trying.
    • Using shorter instructions, asking simpler questions, giving clear examples, and explaining new words.
    • Giving them more time to understand questions and instructions. This allows them to think of their own ideas.
    • Let them use a 'talk partner' about their ideas before sharing them with the class.
    • Repeating and practicing things they have already learned so they can remember and build on them.
    • Working together, like setting goals and planning, to best help the child or young person.
