I'm not sure if my child needs an EHC plan
Most children with special educational needs will have their needs met through extra support provided by the education setting. This is known as SEN Support and can include a wide range of provision and interventions.
However, if an educational setting has exhausted all the possible support options and a child/young person is still not progressing as expected it might be appropriate to request an Education, Health and Care (EHC) needs assessment (the first stage)
The local authority will expect to see evidence of what, if any, progress has been made and that school that have done everything they can to help your child make progress.
