Does anyone have any thoughts about why so few deaf (no other SEN) kids do not achieve the same results as their peers?
Have you ever tried to learn a language?
Have you ever tried to learn a language without hearing it?
GCSEs are all English based and that is the problem. Deaf people are not stupid but it is difficult to acquire literacy and without that it is very difficult to get GCSEs.
Some things that are quite normal for hearing children are difficult for deaf children, say a child is copying from the board, that is all they can do at that time, if the teacher says something then the rest of the class hear it but not the deaf child.
Obviously there has been a lot more technology in the last few years along with statements of SEN and people actually wanting deaf children to learn.
The days of deaf people being trained to work in sorting offices are over.
OP
Is your dd oral or are you using BSL? If you are using BSL then you need to ask about the language levels or any assistants/CSWs, they can actually be quite low.
Have you heard of Mary Hare School? It used to be called Mary Hare Grammar school and at secondary level they still select academically.
If you are considering the deaf school route then do have a look at it. It's boarding but fees are paid by LEAs.
