As this appears to be your first post, welcome to the forum.
I'm a bit confused by your post as there is no middle rate for mobility, so I assume you mean the lower rate, which would be consistent with some one who is deaf.
I can understand why you are concerned about your daughters renewal, but her success at school does not mean that she is any less eligible for DLA.
Just as you did on her previous application, I assume the issues are supervision while out of doors, and amongst others, communicating with others. Unless there has been a significant change in her abilities in these areas, there is no reason to assume that she won't be granted DLA again.
Have a look at our Claiming DLA on Physical Grounds guide in the Members Only area, I would also recommend you have a look at the web sites for some of the UK deaf organisations, as they may be able to offer more specialist help.
If you have more questions, please come back to the forum.
