Diagnostic Evaluations


At CAC, a licensed psychologist provides comprehensive developmental evaluations of children 0 to 6 years old (through 6 years 11 months). In such an evaluation, a concern for autism spectrum disorder, global developmental delay or intellectual disability can be investigated and diagnosed, if appropriate. Standardized diagnostic tools, approved by insurance companies, are used.

Diagnosing for autism spectrum disorder (ASD) involves two initial steps: a developmental screening and a comprehensive diagnostic evaluation.
