What tests are done to diagnose autism?

Based on the cutoff scores that yield the highest accuracy, or ability to identify autism, the SRS diagnosed children with autism with an accuracy of 94 percent, and the SCQ with an accuracy of 80 percent when compared with the clinical diagnoses.
How long does it take to diagnose autism?
Although our results showed that some parents waited around three and a half years to get their child’s ASD diagnosis confirmed, this varied widely – some parents were able to get their child diagnosed almost straight away, whereas others had to wait several years.
