Explore the relationship between poor speech, language and communication and literacy skills

Communication skills are critical in all areas of communication throughout childhood and into adulthood. They are needed for understanding, narrating, making predictions and to develop social skills, for example in understanding everyday language or talking in the classroom or socialising with peers. Children with communication needs can experience low self-esteem, potential behavioural difficulties, lower school attendance and attainment.

Communication skills have a strong impact on literacy. Let’s look at some of the facts:

  • 50% of children with language delays also have challenges with literacy (Burns et al, 1999).
  • 73% of poor readers in year three had a history of difficulties with phonemic awareness (the ability to hear, identify and manipulate sounds) or spoken language in pre-school (Catts et al, 1999).

The effect of expressive language on spelling and reading

The ability to read is very much dependent on competent language skills. Furthermore, a limited vocabulary will also have an impact on literacy skills. The more we know about a word, the easier it is to retrieve, recall, understand and use. So, if a young person has a poorer vocabulary, it’s likely that they will not have the same decoding skills as a peer with a richer set of vocabulary. By decoding we mean the ability to apply knowledge of letter-sound relationships including pronunciation of words. Decoding is a vital skill used in literacy.

Whilst learning to read is a key skill, it’s important to remember that a solid foundation is needed for success. We need to ensure that no steps are missed, otherwise there will be gaps in knowledge.

As your child moves further through the education system, they will be “reading to learn”. This is where young people with poorer language skills may show literacy difficulties (for example, reading comprehensions become more challenging, and their expressive language skills impact on their written abilities).

When should I seek advice or support?

Always seek the advice from a qualified professional such as a Speech and Language Therapist. You need appropriate advice for the age and stage of your child’s development and early intervention is of course key to success. It is never too late to ask for advice. The earlier you seek support, the better the outcome for your child in all areas (language, literacy, and emotional well-being).
