What is classed as an SEN and how do schools identify if a child has one? I believe there is an onus on schools to identify issues and support children, but if a child has no formal diagnosis how does this work? Is it a case of they think a child may have SEN due to x behaviour/issues? Are certain difficulties automatically classed as an SEN? Is any child who requires additional support classed as having SEN? I'm thoroughly confused by it all.
