Speech, Language and Communication Needs (SLCN)

Written by Rachel Whitcombe, Specialist Speech and Language Therapist (HCPC, MRCSLT), 12 years paediatric

Definition

Speech, Language and Communication Needs is an umbrella term for difficulties with understanding language, using language, speaking clearly, or interacting socially. SLCN is one of the four broad areas of need in the SEND Code of Practice (DfE / DoH 2015, paragraphs 6.28–6.30).

In context for parents

Key checkpoints

  • SLCN is an umbrella term for difficulties with understanding language, using language, speaking clearly, or interacting socially.
  • One of the four broad areas of SEND need in the SEND Code of Practice 6.28–6.30.
  • SLCN is the most common area of need in primary-aged children on SEN Support (Code 6.30).
  • Bercow: Ten Years On (2018) found around 7% of UK five-year-olds have a long-term SLCN.
  • Identifying the underlying picture (DLD, speech sound disorder, selective mutism, autism with SLCN) changes the intervention needed.

SLCN is not a diagnosis. It is a need category the school is required to plan around. Underneath it sit specific diagnoses: Developmental Language Disorder, speech sound disorder, stammering, selective mutism, social communication disorder, and the language profile that often runs through autism and learning disability. Identifying which one is the load-bearing picture changes what intervention should look like: a DLD child needs vocabulary and grammar work; a child with a speech sound disorder needs articulation work; an autistic child with SLCN needs pragmatic language and predictability.

In a Reception classroom, SLCN looks like the child who can name what he wants but cannot tell you why he is sad. By Year 2 it is the child who follows the first instruction in "put your book away, line up, and get your coat" and is then lost. By Year 6 it is the child whose SATs reading comprehension is two years behind decoding because the vocabulary and grammar of the question is doing the work the reading is not.

What helps in school: pre-teaching of subject vocabulary before each unit, visual supports for instructions, and SLT-quantified intervention written into Section F if there is an EHCP. The SEND Code of Practice (paragraph 6.30) confirms that SLCN is the most common area of need in primary-aged children with SEN Support.

Bercow: Ten Years On (2018) found that 7% of UK five-year-olds have a long-term SLCN, and that the gap between identification and intervention is the single biggest unmet need in English primary SEND.

Where parents ask about this

Parents usually find this page after a school's SaLT screen has flagged a "low score" without a clear next step, after a long wait for community SaLT input, or before an annual review where the SaLT recommendation is vague enough to be unenforceable. Searches include "private speech therapy UK", "SLCN Section F wording", and "what is the difference between SLCN and DLD". A Beaakon HCPC-registered SaLT can carry out a full language assessment, pinpoint whether the picture is DLD, social communication, speech sound or pragmatic, and write Section F-grade specific, quantified recommendations the LA can be held to.
