The British Dyslexia Association is calling on schools to provide lessons which will help dyslexic children to overcome their difficulties with skills such as reading and writing.

It argues that implementing such a strategy will benefit all pupils, because dyslexic children require highly structured teaching and an emphasis on the sounds of letters within words.

The association says research shows that classes where such teaching takes place provide a good foundation for all children's reading and spelling skills.

Other "dyslexia friendly" strategies which can improve the achievements of non-dyslexic children include helping children to organise their work and employing strategies to build up their confidence.

Around one in 10 UK residents are said to show some dyslexia symptoms.

'Barrier to raising standards'

The Chief Executive of the British Dyslexia Association, Joanne Rule, said: "The government is keen to raise standards in our schools.

"Dyslexia, which is potentially a barrier to raising standards, is more of an issue than ever."

The association's campaign will also call for all infant teachers to be trained to spot signs of dyslexia and for every school to have at least one teacher with a specialist dyslexia qualification.

It will be launched at Penyrheol Comprehensive School in Swansea, South Wales.

Swansea education authority is launching a new initiative on dyslexia, including a charter setting out what dyslexic children can expect from its schools.

"We are delighted that a local education authority is taking action to prevent the misery of underachievement," said Ms Rule.

"We hear so many stories about unhappy children and frustrated parents."
