Speech, Language and Communication Need (SLCN)
Definition of need and how to identify it
Speech, language and communication plays a vital role in our lives. Speech, language and communication skills are needed for socialising, for learning, for well-being and good mental health and to increase opportunities for employment and participation.
SLCN is a collective term to describe all children and young people who have difficulties in communicating with others. They may not be able to express themselves effectively or they may have difficulties in understanding what is said to them. Children with SLCN may have difficulty with one or more aspects of communication.
Speech refers to:
- Saying sounds accurately and in the right places in words.
- The sounds people use to communicate words.
- Speaking fluently, without hesitating, or prolonging or repeating words and sounds.
- Speaking with expression with a clear voice, using pitch, volume and intonation to support meaning.
Language refers to speaking and understanding language:
- Joining words together into sentences, sentences to build up conversations and longer stretches of spoken language.
- Knowing and choosing the right words to explain what you mean
- Making sense of what people say
Communication refers to how we interact with others:
- Using language or gestures in different ways, for example to have a conversation or give someone directions
- Being able to consider other people’s point of view
- Using and understanding body language and facial expressions, such as:
- knowing when someone is bored
- being able to listen to and look at people when having a conversation
- knowing how to take turns and to listen as well as talk
- knowing how close to stand next to someone
There are a variety of signs and clues that might suggest a child or young person has a speech, language and communication need. The list below, includes but is not limited to, the following;
Child or young person struggles to speak clearly or with clarity.
- CYP struggles to listen and hear during a conversation
- CYP might find turn taking challenging
- CYP is finding learning challenging – this could be in all aspects of the curriculum, not just reading and writing.
- They are using the wrong words in speech
- They are making grammatical mistakes
- Relying on stock, standard phrases.
- Struggles to hold a conversation
- Language or vocabulary is advanced or delayed from expected milestones.
- Problems following the invisible rules for conversation and narratives

How prevalent is SLCN in settings and schools?
Over one million children in the UK have some kind of speech language ad communication need.
We know that SLCN can cause significant difficulties for children and young people and that these difficulties can be long term. Based on information on prevalence studies and from schools census date, ICAN estimate that around 10% of all children have long term, persistent SLCN.
Evidence shows 7% of children and young people have SLCN as their main or primary difficulty – known as ‘developmental language disorder’ – previously referred to as SLI ‘specific language impairment’.
Other children have SLCN as a result of another condition, such as autism, ADHD or hearing impairment.
Approximately 1% of these children have the most severe and complex SLCN. This means that 2 – 3 students in every classroom are struggling to communicate.
Children whose first language isn’t English are at no greater risk of speech, language and communication needs than any other child. However there can be challenges with identifying the speech, language and communication needs of children who are learning English as an additional language.
How can you support children and young people in your schools and settings?
The following questions to ask yourself might be helpful to ensure best practice is implemented in learning environments. Please note that the list is not comprehensive and there might a range of strategies to help support children and young people with specific and complex needs.
- Have you adapted your language for the child?
- Have you helped scaffolded the child’s language?
- Have you given the child or young person enough time to process and answer the questions you have asked them?
- Have you asked questions for the child or young person separately and without overloading them?
- Have you used open questions?
- Have you thought about if the child can understand complex words and language?
- Have you ‘pitched the language’ at the appropriate level for them?
- Have you supported what you are saying with visuals like pictures, signs and gestures?
- Have you ensured there are open/comfortable spaces inside and outside the building for child or young person to talk?
- Are noise levels manageable?
- Are spaces labelled?
- Have resources and materials got visuals such as pictures or symbols on them?
- Have children and young people been provided an opportunity to communicate with their peers?
- Is it appropriate for their age-group?
- Has the child or young people been given the opportunity to be taught and develop coping skills that work best for them to manage frustration or disruptive behaviour?
- Have they had the opportunity to understand their own emotional wellbeing and know the consequences of not looking after their emotional needs*?
*All human beings have emotional needs. Children and young people who have speech, language and communication needs might find expressing and regulating emotions challenging although it varies for every individual.

How to raise concerns
We recommend that the professional who has noticed the behaviour and signs of needs start observing and documenting what they notice. This is then shared with SENCo’s or designated members of staff. This could then lead to identification with a specialist professional.
In the case that the child or young person needs targeted support in education, please look at the Referral for Involvement form on CYPSinfo and send to InclusiveEducation@northyorks.gov.uk.
