Communication and Interaction

Understanding the area of need

Last reviewed: February 2026

Overview

Communication and Interaction is one of four areas of need identified in the SEND Code of Practice (2015). This category includes children who have autism spectrum condition (ASC) and those with speech, language and communication needs (SLCN).

Speech, language and communication needs is the broad umbrella term used in UK education to describe a wide range of difficulties. Research indicates that around 10% of all children have some form of SLCN. Some may have a specific diagnosis such as Developmental Language Disorder (DLD), while others may have communication difficulties associated with other conditions.

The Bercow Report (2008) and subsequent Bercow: Ten Years On review (2018) highlighted the critical importance of early identification and support for children with SLCN, emphasising that communication is the foundation for learning, wellbeing, and life outcomes.

The Three Components of Communication

SpeechLanguageCommunication
  • Producing sounds accurately and in the correct places within words
  • The sounds people make to communicate words
  • Speaking fluently without hesitating, prolonging or repeating words or sounds (fluency)
  • Using appropriate pitch, volume, intonation and rhythm to support meaning (prosody)
  • Receptive language: understanding what others say, following instructions, comprehending vocabulary and sentence structure
  • Expressive language: using words to build sentences, using grammar correctly, and formulating ideas into spoken language
  • Pragmatic language: using language appropriately in social contexts, understanding turn-taking, and recognising conversational cues
  • Using language to represent concepts, express thoughts, and convey meaning
  • Using language functionally to question, clarify, describe, request and comment
  • Non-verbal communication including listening skills, facial expressions, eye contact, gesture and body language
  • Understanding social context and adjusting communication accordingly

Key Terms

SLCN (Speech, Language and Communication Needs): The broad umbrella term used in UK education for all children who have difficulties with speech, language or communication.

DLD (Developmental Language Disorder): A specific diagnosis for children who have persistent difficulties with understanding or using language, where these difficulties are not associated with a known biomedical condition such as hearing loss, neurological damage, or autism. DLD is defined by the CATALISE consortium (2017) and is increasingly recognised in UK schools.

ASC (Autism Spectrum Condition): A lifelong developmental difference that affects how a person communicates, interacts socially, and experiences the world. Communication differences in autism have distinct characteristics and are addressed on the autism-specific page.

Key point: A child may have difficulty with speech, language, communication, or any combination of the three. Their difficulties may be mild or severe and may change over time. Each child's profile of strengths and needs is unique.
