Autism diagnosis delays in Wales are impacting education

There are fears some children with suspected autism are missing out on a specialist education because waiting times for diagnosis are increasing.
In the Hywel Dda local health board area, 311 children have been diagnosed but a further 340 are still waiting to be assessed.
Appropriate education provision is difficult without a correct diagnosis.
In 2012, BBC Wales found some children were waiting longer than seven years for a diagnosis.
