DEAF pupils face a postcode lottery when it comes to standards of education, says a survey.
But youngsters in Huddersfield fare much better.
Research by the Royal National Institute for the Deaf revealed that in many areas deaf pupils were not getting a fair deal.
A spokeswoman said: "The limited provision of specialist support in mainstream schools could be damaging their education."
About 44% of schools with specialist deaf resource centres do not have fully-qualified staff.
About 25% of staff are not even in training.
But deaf pupils in Kirklees are being well served.
In Kirklees, there are 352 deaf children and 305 of them are educated in mainstream schools.
Teachers are given deaf awareness training and have advice and support peripatetic staff from the council's service for children with sensory impairment.
Jan Parkin, the head of the service, said: "Deaf awareness training is in the package of support we offer to all schools where there are deaf children."
As well as training, the service offers classroom support from fully-qualified peripatetic teachers for the deaf.
Some children also qualify for cash to pay for special classroom equipment.
The 43 children in Kirklees with more severe hearing problems are educated in one of three special deaf resource centres - at Newsome High School and Sports College, Lowerhouses Junior, Infant and Early Years School and Park Road Junior, Infant and Nursery School at Batley.
At schools with resource centres, there are fully-qualified teachers of the deaf and communicators who teach sign language. They offer sign language in each class where there is a deaf child.
Another major issue raised in the RNID report was the shortage of teachers for the deaf.
These teachers must gain a specialist qualification, as well as the standard teaching qualifications.
This takes two years - costing £1,800 a year - and in many areas the trainee foots the bill.
This has led to a lack of teachers. There are only 2,400 in Britain.
But in Kirklees the council has been securing cash to pay for teachers' training for 10 years.
The council is supporting three first-year trainee teachers for the deaf, one second year on the same course and one second-year trainee teacher for multi-sensory impairment.
One unqualified teacher of the deaf is being given in-house training.
But Mrs Parkin said: "There is a shortage of teachers of the deaf locally."
