ADOS-2

Autism Evaluations

This evaluation will often begin with a diagnostic instrument such as the Autism Diagnostic Observation Schedule, or the ADOS-2. The ADOS is a test with different modules to accommodate a range of children. There is a version for toddlers that is play-based. For kids older than thirty months, there are modules that include more conversation, according to the child’s language level.

This is not the kind of test where there are right answers. The purpose of the ADOS is to evaluate the social skills and repetitive behaviors the child displays during the test. This means the evaluator is paying attention to things like if the child asks for help when he needs it, gives other people a chance to speak, and follows along with changes of subject.


A Developmental Delay is suspected when a child does not reach developmental milestones within the expected time-frame. It is an ongoing, major delay in the process of development, rather than a slight or temporary lag behind in expected milestones. A developmental evaluation involves an assessment of your child’s intelligence (or current developmental functioning), language, and visual-motor skills. If concerns about autism or a pervasive developmental disorder are present, your child may be given the ADOS (Autism Diagnostic Observation Schedule) along with other assessment measures as part of the developmental evaluation. Further, parent and teacher/caregiver interviews and rating forms are an important part of the evaluation. The evaluation typically takes two to three sessions to complete, each lasting 1-2 hours.  These services are provided by psychologists in both our Lancaster, PA and Reading, PA offices.
