She made the call last week launching the document Educational Services for Children and Young People with Visual Impairment, which is out for consultation until 30 September.
The disparity in service provision has arisen because all 22 local education authorities in Wales determine their own policies for identification and intervention, staffing levels of specialist teachers are inconsistent, and the availability of mobility officers is variable.
Ms Davidson said, 'We need to ensure there are sufficient numbers of specialists who can provide support through the medium of Welsh across all areas. The consultation document includes standards of excellence which will give LEAs guidance as to what is expected within their service delivery. By having uniform national standards, support services can ensure that they are achieving best practice.'
She said the problem of recruiting and retaining qualified teachers was being tackled through a re-examination of the regulations relating to teachers' work and qualifications and the development of a mandatory qualification for those teaching visually impaired pupils. There would also be funding for a bilingual e-learning course in special education for teacher education students, newly qualified teachers and learning support assistants.
The consultation document, which is based on the findings of an audit of educational support services by the Welsh Assembly last year, revealed that 1,278 children and young people were identified as visually impaired - 10 per cent of them in mainstream schools - and there were 49 specialist qualified teachers and eight mobility officers working in the 22 LEAs.
The document has called for an equitable referral system so that all children and young people who may have visual difficulties affecting their education can have access to an assessment by a qualified teacher of the visually impaired. They should then be provided with mobility training as well as road safety instruction.
* A social club for children and young people with disabilities in West Glamorgan is among seven Welsh winners of the Queen's Golden Jubilee award for 2004. The club has a ballpool, soft play area, trampolining, pottery class and multi-sensory room, while outside there are go-karts and a new wheelchair swing.
Dawn Sawyers, chairwoman of the Special Needs Activity Club at Margam near Port Talbot said, 'We are delighted to win this award and feel proud of the work we do here with disabled children and young people.'
