When I started in my current school I wanted to check all parents actually knew their children were on the SEN register, I did this gradually at first as I spoke to them and then confirmed it in a letter. The letter has a slip at the bottom which I ask parents to sign and return so I have confirmation that they know their child is on the SEN register. I have very occasionally had parents say they do not want their child on the SEN register and I have accepted this although I think technically children can be put on without parent consent. I now send out children’s individual provision plans to parents every term as a kind of ongoing confirmation that the child is on the SEN register. And for any child that I now think should be added to the SEN register I discuss this with parents first. So it should be no surprise to any parent that their child is on the register. On the letter I also specify the area of need / needs that the child is on the register for.
