Scoring & interpretation
Using a standardized grid, the clinician rates several behaviors during different situations or interactive games. Scores are coded according to the frequency and quality of the observed behaviors, then entered into module-specific algorithms to provide an overall score that allows ASD risk to be interpreted.
