SRS-3
The Social Responsiveness Scale, Third Edition (SRS®-3), is a norm-referenced autism assessment tool that measures social responsiveness, social communication, and autism-related behaviours across the lifespan. The SRS-3 Social Responsiveness Scale provides structured behavioural data to help practitioners assess social communication challenges and support diagnostic decision-making for autism and related conditions. The SRS-3 supports comprehensive autism assessment, treatment and intervention planning, progress monitoring, school eligibility determinations, and research.Coming SoonPearson Clinical distributes but does not publish this product.

Assess Across the Lifespan
The SRS-3 includes forms for individuals from 2 years, 6 months through adulthood, allowing practitioners to assess social responsiveness and autism-related behaviours across the lifespan. Parent and/or teacher forms are available for preschoolers and school-age individuals, alongside self-report forms for school-age individuals and adults and an Adult Relative/Other Form.
Forms
- Preschool Form (2:6–4:6): Completed by a parent/primary caregiver or teacher/other professional
- School-Age Form (4:0–18:11): Completed by a parent/primary caregiver or teacher/other professional
- School-Age Self-Report Form (11–18:11): Completed by the child or adolescent being assessed
- Adult Self-Report Form (18 and older): Completed by the adult being assessed
- Adult Relative/Other Form (18 and older): Completed by a family member, spouse, partner, friend, or colleague
What the SRS-3 Measures
The SRS-3 provides three types of norm-referenced T-scores: SRS-3 Total Score, two DSM-Compatible Scale scores, and six Treatment Subscale scores.
SRS-3 Total Score
The SRS-3 Total Score is a global index of social responsiveness based on the frequency of observed behaviours. This is the primary score used for measuring the extent of autism-related behaviours assessed by the SRS-3.
DSM-Compatible Scales
The DSM-Compatible Scales assess autism-related behaviours aligned with the two criterion domains for the identification of autism. These scores are intended to provide additional context for the SRS-3 Total Score and inform decisions about diagnosis and eligibility.
- Social Communication and Interaction (SCI)
- Restricted Interests and Repetitive Behaviours (RRB)
Treatment Subscales
The Treatment Subscales measure specific types of behaviour related to reciprocal social interaction and the characterising traits of autism. Together, these scores describe patterns of behaviour that may inform clinical interpretation, treatment plans, and other interventions.
- Social Awareness
- Social Cognition
- Social Communication
- Social Motivation
- Cognitive Flexibility
- Sensory–Motor Behaviour
The Social Responsiveness Scale, Third Edition (SRS®-3) is a norm-referenced rating scale that measures social responsiveness, the ability to engage in reciprocal, socially appropriate interactions, and autism-related behaviours across the lifespan.
As part of a comprehensive evaluation, the SRS-3 enables practitioners to gather structured behavioural data for diagnostic decision-making, school eligibility determinations, treatment/intervention planning, and progress monitoring.
The SRS-3 provides three types of norm-referenced T-scores: the SRS-3 Total Score, two DSM-Compatible Scale scores, and six Treatment Subscale scores.
The SRS-3 Total Score is a global index of social responsiveness based on the frequency of observed behaviours. The DSM-Compatible Scales assess autism-related behaviours aligned with the two criterion domains for the identification of autism: Social Communication and Interaction (SCI) and Restricted Interests and Repetitive Behaviors (RRB).
The six Treatment Subscales measure Social Awareness, Social Cognition, Social Communication, Social Motivation, Cognitive Flexibility, and Sensory–Motor Behavior.
The SRS-3 assesses individuals from 2 years, 6 months through adulthood, with forms available across the lifespan:
- Preschool (2:6–4:6): completed by a parent/primary caregiver or teacher/other professional
- School-Age (4:0–18:11): completed by a parent/primary caregiver or teacher/other professional
- School-Age Self-Report (11–18:11): completed by the child or adolescent being assessed
- Adult Self-Report (18 and older): completed by the adult being assessed
- Adult Relative/Other (18 and older): completed by a family member, spouse, partner, friend, or colleague
The SRS-3 takes approximately 15–20 minutes to complete per form.
The SRS-3 provides norm-referenced T-scores, including an SRS-3 Total Score, two DSM-Compatible Scale scores, six Treatment Subscale scores, and an Inconsistent Responding Index.
For digital administration through WPS Hub™, ratings can be validated and scored automatically, with results available immediately.
Paired with observations, interviews, and other standardised tools, the SRS-3 adds structured behavioural data from those who see the individual in everyday life, strengthening clinical decision-making when evaluating for autism.
The SRS-3 can be used to support differential diagnosis between autism and other conditions, strengthen clinical reports with quantifiable multi-respondent data, compare ratings across respondents, inform intervention planning, track change over time, and communicate findings to families and educational teams.
While the SRS-3 retains the essential characteristics of previous editions, the new revision includes updated standardised T-scores derived from a nationally representative US normative sample, three norm options for all forms, and a new School-Age Self-Report Form.
The SRS-3 also includes new items capturing reciprocal social skills, updated item wording for clarity and inclusivity, new Cognitive Flexibility and Sensory–Motor Behavior Treatment Subscales, a new Inconsistent Responding Index, new clinical validity studies, updated interpretation guidelines, and new online administration and scoring options.
