SEN Support Leaflet – available here: sen-support-in-mainstream-schools
The changes to SEN (Special Educational Needs) that happened as part of the Children and Families Act 2014 took away the School Action and School Action plus categories for SEN and replaced them with one category SEN Support – sometimes called the Graduated Approach. This applies to any child or young person who has been identified as having special educational needs.
Parent representatives from HPCI have worked with Herts County Council to produce this leaflet that explains to parents what is meant by SEN and what should happen in schools and other education settings. If you want more detail then you can look at this in the SEND Code of Practice – Chapter 5 covers the Early Years, Chapter 6 Schools and Chapter 7 16 plus. The link to the SEN Code of Practice is here
