Special educational needs (SEN)
Special educational needs (SEN)
The School offers a wide range of support for students for whom English is an additional language. The SEN definitions recognise learning difficulties and other disabilities, including conditions that may affect the ability to access the curriculum. For students with identified needs, an Individual Education Plan (IEP) is prepared in consultation with parents and the student, and an Action Plan or Collaborative Action Plan may be used to address educational, behavioural or pastoral concerns. A provision map documents the supports available and informs teachers of the student's plan. If a student has an Educational Health and Care Plan (EHC plan), the School will collaborate with the local authority to deliver the provision, and additional services may be funded by the local authority where applicable. The Learning Resource Centre (LRC) staff liaise with teachers to differentiate instruction and monitor progress as part of the wider welfare and pastoral process.
