Severe Learning Difficulty (SLD)

Written by Helen Marsh, Senior SENCO (NASENCo, MA SEN), 14 years mainstream and specialist

Definition

Severe Learning Difficulty is the SEND Code of Practice category for children with significant intellectual or cognitive impairment, typically with a standard score below 55, who require a highly adapted curriculum delivered in a specialist or specialist-resourced setting. Most children with SLD have an EHCP from the early years onwards.

In context for parents

Key checkpoints

  • SLD is the SEND Code of Practice category for children with significant intellectual impairment, typically with a standard score below 55.
  • Most children with SLD have an EHCP from the early years.
  • Curriculum in SLD provision is built around the Engagement Model (DfE 2020) and the pre-Key Stage standards.
  • Section I almost always names a specialist SLD provision.
  • Section F quantifies SaLT, OT, sometimes physio, adult support ratios, and named curriculum programmes.

SLD describes a global learning profile two or more standard deviations below age expectation, usually identified well before school entry through the integrated 0–25 health and education pathway. Many children with SLD have a named underlying condition: Down's Syndrome, Fragile X, undiagnosed chromosomal variation, perinatal brain injury, complex epilepsy. Some do not, and the picture is described instead by adaptive function: the day-to-day skills needed to dress, eat, communicate, learn, and stay safe.

In a Year 3 SLD class in a special school, the curriculum is built around the Engagement Model (DfE statutory, 2020) for pupils not yet engaged in subject-specific learning, and the pre-Key Stage standards for those who are. Communication may be sign, symbol, AAC, or developing speech. Toileting, eating, and dressing are taught explicitly as part of the day. The picture is not "behind"; it is a different curriculum.

What works: a structured visual environment (TEACCH or similar), AAC modelled by every adult, SaLT and OT integrated into daily routines rather than withdrawn as a weekly session, and physical activity built into the day. The same routine repeated rather than reasoned through, with novelty introduced gradually. Family-school communication is daily.

Section I almost always names a specialist SLD provision. Section F quantifies SaLT, OT, sometimes physio, plus adult support ratios and named curriculum programmes. The annual review is where the working document is built collaboratively, with parents bringing their long-view of the child to a meeting that otherwise risks defaulting to "she's doing well in school".

Where parents ask about this

Parents usually find this page when an early years EHCP is being drafted, before a secondary or post-16 transfer where the next provision is being chosen, or where mainstream inclusion has been pushed beyond the point at which the child can flourish. Searches include "SLD special school placement", "Engagement Model EHCP outcomes", and "post-16 SLD provision". A Beaakon EP or specialist teacher can carry out a profile that supports the right specialist placement and write Section F provision matched to the curriculum the child actually needs.
