A child has special educational needs (SEN) if he or she has learning difficulties or disabilities that make it harder for him or her to learn than most other children of about the same age.
Many children will have special educational needs of some kind during their education. Schools and other organisations can help most children overcome the barriers their difficulties present quickly and easily. A few children will need extra help for some or all of their time in school.
So special educational needs could mean that a child has:
Children make progress at different rates and have different ways in which they learn best. Teachers take account of this in the way they organise their lessons and teach. Children making slower progress or having particular difficulties in one area may be given extra help or different lessons to help them succeed.
You should not assume, just because your child is making slower progress than you expected or the teachers are providing different support, help or activities in class, that your child has special educational needs.
