Autism Spectrum Rating Scales

Sam Goldstein, Ph.D. , Jack A. Naglieri, Ph.D.


Effectively identifies symptoms, behaviors, and features of ASD in ages 2-18


A multi-informant measure designed to identify symptoms, behaviors, and associated features of Autism Spectrum Disorder (ASD) in children and adolescents aged 2 to 18 years.

This innovative instrument, authored by the highly respected Sam Goldstein, Ph.D., and Jack A. Naglieri, Ph.D., is a norm-referenced assessment based on a nationally representative sample, designed to identify symptoms, behaviors, and associated features of the full range of Autism Spectrum Disorders. The ASRS assists in the diagnostic process, guides the development of intervention and treatment strategies, and monitors the response to intervention and treatment effectiveness.

Key Features:

  • First nationally-standardized, norm-referenced ASD Rating Scale
  • Easy administration, scoring, and results interpretation
  • Excellent reliability and validity
  • Short version can be used for screening or treatment monitoring
  • Spanish version available
  • Items assess DSM-5 symptom criteria for ASD - DSM-IV-TR scoring still available for online and software options
  • Option to score children with limited verbal abilities

Inform diagnosis, treatment planning, and educational placement with an observational assessment of Autism Spectrum Disorder


The Autism Diagnostic Observation Schedule, Second Editionis an observational assessment of Autism Spectrum Disorders (ASDs). It is a semi-structured, standardized assessment of communication, social interaction, play, and restricted and repetitive behaviours. It presents various activities that elicit behaviours directly related to a diagnosis of ASD. By observing and coding these behaviours, you can obtain information that informs diagnosis, treatment planning, and educational placement.

Key Features:

  • Clear and explicit administration and coding instructions with updated Protocol Booklets
  • Revised algorithms for Modules 1 through 3 to provide a more uniform basis for comparing results across the three modules used with children and young adolescents
  • The ability to assess toddlers who do not consistently use speech with a Toddler Module for children aged 12 to 30 months

Key Areas Measured

  • Communication
  • Social Interaction
  • Play
  • Restricted and Repetitive Behaviors

Assess individuals suspected of having an Autism Spectrum Disorder in ages 2 and older


The ADI-R helps to assess individuals suspected of having Autism or an Autism Spectrum Disorder.

  • Can support diagnostic decisions
  • Assists in differentiating autism from other disorders
  • Provides an empirically validated basis for education and treatment planning
  • Particularly effective in assessing syndrome boundaries, identifying new subgroups, quantifying Autistic symptomatology, and determining the clinical needs of groups in which a high rate of Autism Spectrum Disorders might be expected, such as people with severe language impairments

Key Areas Measured

  • Language and Communications
  • Reciprocal Social Interactions
  • Restrictive, Repetitive, and Stereotyped Behaviors and Interests
