The ADOS includes four modules: 1. Module 1: For children with little or no phrase speech. 2. Module 2: For children with phrase speech but not fluent language. 3. Module 3: For children and adolescents with fluent language. 4. Module 4: For older adolescents and adults with fluent language.
Each module is designed to assess specific developmental and linguistic capabilities, ensuring that the assessment is appropriate for the child's level of functioning.
