A BLOWOUT in the number of autistic students at NSW public schools may have been triggered by doctors misdiagnosing children to secure extra funding.
Department of Education figures obtained by The Sunday Telegraph show one in 74 students at state schools is autistic despite the accepted Australian prevalence being one in 160.
The state government spends more than $1.1 billion each year on students with disabilities.
Doctors say the only way to secure extra funding for children who are borderline cases or who have learning difficulties is to stretch the diagnosis.
