'My daughter's autism diagnosis took six years'
The amount of time it takes for autism to be diagnosed should be monitored by NHS England, the National Autistic Society (NAS) says.
The charity says delays between being referred to an autism specialist and diagnosis are "unacceptably long" and putting "families into crisis".
A report by Public Health England has shown there is a huge disparity in waiting times across England - but NHS England says it is committed to reducing waiting times.
The BBC's Jean Mackenzie has been speaking to Vanessa and her daughter Becky, 10, who has autism. It took them six years to get Becky's diagnosis.
