What is the SRS-2?

The Social Responsiveness Scale, Second Edition (SRS-2; Constantino & Gruber, 2012) is a norm-referenced rating scale that measures the severity of social impairment associated with Autism Spectrum Disorder. It is completed by a parent, caregiver, teacher, or the individual themselves — not through direct testing. The SRS-2 quantifies social deficits across five subscales, producing T-scores that reflect the degree to which a person's social behavior deviates from age expectations. It is used as part of a comprehensive AU evaluation battery, not as a standalone diagnostic instrument.

🎯 Role in AU Evaluation

The SRS-2 serves several functions in a Texas AU evaluation:

Quantifying severity — T-scores provide a standardized measure of social impairment severity that supports the "adverse educational effect" criterion

Cross-informant comparison — parent and teacher forms together document whether social impairment is pervasive across settings (required for DSM-5 Criterion A)

Subscale profiling — the five subscales map closely to DSM-5 AU criteria, supporting documentation of specific social communication and RRB patterns

Differential diagnosis — the subscale profile helps distinguish AU from ADHD, ED, SLI, and other presentations

⚠️ What the SRS-2 Is NOT

Not diagnostic: No single rating scale, including the SRS-2, establishes or rules out an AU diagnosis. Elevated T-scores indicate significant social impairment consistent with AU but are not sufficient for eligibility determination on their own.

Not a replacement for ADOS-2 or MIGDAS-2: The SRS-2 is a rating scale based on informant report — it does not involve direct behavioral observation. It complements observational measures, not replaces them.

Not immune to rater bias: Scores reflect the respondent's perception and are influenced by their relationship to, familiarity with, and expectations of the individual.

Always document which form was used and who the respondent was. A parent SRS-2 of 78 and a teacher SRS-2 of 52 tell very different stories — and both matter.

📐 Score Structure

Total Score T-score — overall severity of social impairment (M=50, SD=10)

5 Subscale T-scores:
• Social Awareness (SA)
• Social Cognition (SC)
• Social Communication (SCM)
• Social Motivation (SM)
• Restricted/Repetitive Behavior (RRB)

Rating scale: 65 items, 4-point Likert — Not True (1), Sometimes True (2), Often True (3), Almost Always True (4)

Reference period: Past 6 months

👥 Who Can Administer

The SRS-2 is generally within diagnostician scope — it is a rating scale, not a performance-based or interview-based measure. In most Texas districts, the diagnostician administers the parent and teacher forms as part of the AU evaluation battery.

The Adult Self-Report Form may require clinical judgment about whether self-report data is valid and reliable for a given individual — consider insight, literacy, and cognitive level.

The SRS-2 is most meaningful when cross-informant data is available. Single-rater data should be interpreted cautiously.

Five Subscales — DSM-5 Mapping

The SRS-2 subscales were designed to align with the dimensions of social impairment in Autism Spectrum Disorder. The first four subscales (SA, SC, SCM, SM) correspond broadly to DSM-5 Criterion A (social communication and interaction deficits); the fifth subscale (RRB) corresponds to DSM-5 Criterion B (restricted/repetitive behaviors). This makes the SRS-2 subscale profile directly useful for FIE documentation of the AU criteria pattern.

Social Awareness

SA · DSM-5 Criterion A

Ability to pick up on social cues — noticing what others are doing, following gaze, recognizing nonverbal signals, orienting to social stimuli. Deficits here reflect difficulty perceiving the social environment.

What elevation looks like: Student misses social cues that peers pick up naturally — may not notice when someone is upset, fail to track where others are looking or what they are attending to, or miss nonverbal signals about what a situation expects of them.

Social Cognition

SC · DSM-5 Criterion A

Ability to interpret social cues once perceived — understanding intent, inferring meaning, theory of mind. Deficits here reflect difficulty making sense of what others mean, feel, or intend.

What elevation looks like: Student interprets language very literally, missing sarcasm, humor, or implied meaning; has difficulty understanding why social events unfolded as they did; or focuses on specific details while losing the broader social context or intent.

Social Communication

SCM · DSM-5 Criterion A

Ability to use language in social contexts — pragmatic communication, back-and-forth conversation, appropriate tone and expression, communicating feelings. The largest subscale and often the highest-scoring in AU.

What elevation looks like: Student has difficulty with conversational back-and-forth — may talk at length on preferred topics without reading listener cues, use atypical prosody or tone, struggle to answer questions directly, or show facial expressions that don't match the emotional content of what they are saying.

Social Motivation

SM · DSM-5 Criterion A

Desire and drive to engage socially — initiating interactions, joining groups, seeking social connection, emotional closeness. Deficits reflect reduced interest in social engagement, not just difficulty with it.

What elevation looks like: Student shows limited interest in seeking out peers, prefers solitary activities, avoids joining group interactions without adult direction, or appears emotionally withdrawn from the social environment of the classroom.

Restricted/Repetitive Behavior

RRB · DSM-5 Criterion B

Repetitive behaviors, rigid routines, restricted interests, sensory sensitivities, and inflexibility. The only subscale corresponding to DSM-5 Criterion B — its elevation is essential for documenting the full AU picture.

What elevation looks like: Student engages in repetitive motor movements or vocalizations, shows intensely focused interest in a narrow range of topics, demonstrates notable sensory sensitivities to sounds, textures, or smells, and resists changes to routines or expectations with significant inflexibility.

SCI vs. RRB split: The SRS-2 manual also reports a two-factor composite: the Social Communication and Interaction (SCI) index combines SA + SC + SCM + SM, and the RRB index stands alone. This split maps directly to DSM-5's two-domain structure (Criterion A = SCI; Criterion B = RRB) and is useful for FIE documentation. Both composites must show meaningful elevation for a pattern fully consistent with AU.

Subscale profile interpretation: In AU, Social Communication is typically the highest subscale score. High RRB with lower social subscale scores may suggest OCD, anxiety, or ADHD rather than AU. High Social Motivation with intact Social Awareness may suggest social anxiety or ED rather than AU. The pattern of subscale elevations is more informative than the total score alone.

Forms, Age Ranges & Raters

The SRS-2 includes five forms across three age bands. All forms contain 65 items rated on a 4-point scale covering the past 6 months. Cross-informant comparison — collecting both parent and teacher forms — is strongly recommended and often essential for demonstrating pervasiveness of social impairment across settings.

Form	Age Range	Respondent	Items	Spanish?	Notes
Preschool Form	2:6–4:11	Parent, caregiver, or teacher	65	❌	Items adapted for young children; item 32 asks about diaper/underwear awareness rather than personal hygiene
School-Age Form	4:0–18:11	Parent, caregiver, or teacher	65	✅ Yes	Most commonly used form in school-age AU evaluations; Spanish translation by Susana Urbina, PhD; same 65 items, identical scoring
Adult Self-Report Form	19+	Individual being evaluated	65	❌	First-person phrasing ("I..."); consider whether self-insight is sufficient for valid self-report; useful for adult AU evaluations
Adult (Relative/Other) Form	19+	Spouse, family member, significant other	65	❌	Third-person phrasing; rater options include mother, father, other relative, spouse, other; complements self-report for adult evals

Spanish Form — School-Age

The Spanish-language School-Age Form (translated by Susana Urbina, PhD) covers the same 65 items with identical scoring and interpretation. It is appropriate for parents or caregivers who are more proficient in Spanish than English. The same normative tables apply — document in the FIE that the Spanish form was used and who completed it.

For EB/EL students, consider using the Spanish form for the parent rater and the English form for the teacher. This cross-form comparison reflects real-world practice, though rater differences should be attributed to both respondent and language factors when interpreting discrepancies.

Administration Notes

⏱️ Completion Time

Approximately 15–20 minutes for most respondents. Can be completed independently (mailed, emailed, or handed to parent/teacher) or administered as a structured interview. The structured interview approach allows for clarification of ambiguous responses.

📅 Reference Period

"Past 6 months" — items ask about typical, recent behavior, not historical or current-only behavior. Ensure the respondent has had sufficient contact with the individual over the past 6 months. At least one month of regular daily contact is recommended for valid ratings.

🔢 Scoring

Items are scored 1–4 (Not True through Almost Always True). Some items are reverse-scored (positively worded items like "Is self-confident," "Has good humor" score in the reverse direction — higher ratings on these items reduce the total score). Raw scores convert to T-scores via the normative tables.

T-Score Severity Classification

SRS-2 scores are reported as T-scores (mean=50, SD=10). Higher scores indicate greater severity of social impairment. The SRS-2 manual provides four severity classifications based on T-score range, applicable to both the Total Score and the five subscale scores.

≤59 Within Normal Limits

60–65 Mild

66–75 Moderate

≥76 Severe

← Less impairment More impairment →

T-Score Range	SRS-2 Classification	Educational Interpretation	AU Implications
≤59	Within Normal Limits	Social responsiveness within expected range for age	Does not support AU social impairment profile; consider other explanations for referral concerns
60–65	Mild	Mild deficits in social responsiveness; may reflect subclinical traits, situational factors, or co-occurring concerns	Mild elevation — may reflect AU traits in a high-functioning individual, anxiety, ADHD, or social immaturity; interpret with full evaluation data
66–75	Moderate	Moderate social impairment significantly affecting daily social functioning across settings	Consistent with AU social profile when pervasive across raters and settings; supports adverse educational effect documentation
≥76	Severe	Marked social impairment with substantial interference in daily social functioning	Strongly consistent with AU social profile; document alongside other AU evaluation data; note severity in FIE impact statement

Gender considerations: SRS-2 T-scores are gender-normed — separate norms exist for males and females. Girls with AU frequently score lower on the SRS-2 than boys with equivalent functional impairment, reflecting the "female AU phenotype" — better social masking, more internalized presentation, stronger motivation to socially camouflage. A T-score in the Mild range for a girl with other AU indicators warrants the same clinical attention as a Moderate score in a boy. Document this interpretive nuance in the FIE.

Subscale vs. Total Score

All five subscales and the Total Score are reported as T-scores using the same severity classification table above. When interpreting the profile:

Total Score — best indicator of overall social impairment severity; use for eligibility documentation and cross-informant comparison

Subscale scores — identify specific areas of impairment; map to DSM-5 criteria; useful for FIE narrative and ARD recommendations

SCI composite (SA + SC + SCM + SM) — reflects DSM-5 Criterion A severity
RRB subscale — reflects DSM-5 Criterion B severity

Both SCI and RRB should show meaningful elevation for a pattern fully consistent with AU. Isolated RRB elevation without social communication impairment is not consistent with AU.

Cross-Informant Analysis

The most clinically valuable use of the SRS-2 is comparing scores across raters — typically parent and teacher. DSM-5 requires that AU symptoms be present across multiple settings, making cross-informant consistency an important piece of the eligibility documentation puzzle. Discrepancies are equally informative and require explanation.

Common Cross-Informant Patterns

Pattern 1 — Concordant Elevation (Both Raters Elevated)

Parent T=74 Teacher T=70

Both raters report significant social impairment — this is the strongest pattern for documenting pervasiveness across settings required by DSM-5. The consistency of concerns across home and school strengthens the AU evaluation. Document that both raters independently identified meaningful social impairment.

Pattern 2 — Parent Elevated, Teacher Within Normal Limits

Parent T=72 Teacher T=54

Common in students who mask effectively at school but decompensate at home. May also reflect greater home demands, less structure, or the parent's deeper knowledge of subtle behaviors not visible in the classroom. Consider: Does the student show fatigue or emotional dysregulation after school? Does the classroom environment provide scaffolding that compensates for social deficits? This pattern does not rule out AU — document contextual factors that explain the discrepancy.

Pattern 3 — Teacher Elevated, Parent Within Normal Limits

Parent T=55 Teacher T=71

Less common in AU than Pattern 2, but possible. May reflect the highly structured social demands of the classroom exposing deficits not as apparent in the home environment. Consider whether the home environment has fewer peer interaction demands, more parental accommodation, or whether the parent's familiarity normalizes behaviors that the teacher perceives as unusual. Document contextual differences between settings.

Pattern 4 — Both Within Normal Limits

Parent T=52 Teacher T=48

Both raters report social responsiveness within normal limits. This pattern does not support an AU social profile on the SRS-2. While it does not rule out AU entirely (especially in high-masking individuals), it significantly weakens the case and requires strong evidence from other sources (direct observation, ADOS-2/MIGDAS-2, history) to proceed toward AU eligibility. Document clearly in the FIE.

Masking and late identification: Girls, high-functioning individuals, and older students often show lower SRS-2 scores than their functional impairment warrants due to social masking — learned compensatory behaviors that suppress observable symptoms at the cost of significant internal effort and post-school decompensation. A Within Normal Limits or Mild SRS-2 score in a student with a detailed history of social difficulties, a parent reporting exhaustion after social interactions, and classroom observation showing scripted rather than spontaneous social behavior warrants clinical caution about dismissing AU on the basis of the SRS-2 alone.

Interpreting Score Differences

The SRS-2 manual provides guidance on statistically significant differences between raters, but in practice, a T-score difference of 10+ points between raters should always be explained in the FIE — regardless of statistical significance — because it represents one full standard deviation in perception of social impairment.

Document: Which rater scored higher, what contextual factors might explain the discrepancy (setting demands, masking, accommodation level, relationship familiarity), and how the discrepancy is interpreted in the context of the full evaluation profile.

FIE Language Models

Edit all models to reflect actual scores, rater, and context. Always name which form was used and who completed it. Use the SRS-2's own classification language (Within Normal Limits, Mild, Moderate, Severe) rather than inventing descriptors. Never use "clinically" — use "educationally significant" or describe the functional impact directly.

Instrument Introduction

Standard Introduction — School-Age, Parent Rater

Social responsiveness was assessed using the Social Responsiveness Scale, Second Edition (SRS-2; Constantino & Gruber, 2012), School-Age Form, completed by [Student]'s [mother/father/caregiver]. The SRS-2 is a norm-referenced rating scale that measures the severity of social impairment associated with Autism Spectrum Disorder across five subscales: Social Awareness, Social Cognition, Social Communication, Social Motivation, and Restricted/Repetitive Behavior. Scores are reported as T-scores (mean = 50, SD = 10); higher scores indicate greater severity of social impairment.

Spanish Form Notation

The SRS-2 School-Age Form was completed in Spanish by [Student]'s [mother/father/caregiver], as [he/she/they] is more proficient in Spanish than English. The Spanish translation was developed by Susana Urbina, PhD, and uses the same normative tables as the English form. Administration, scoring, and interpretation are identical.

Score Reporting

Single Rater — Score Summary

[Student]'s [parent/teacher] rated [him/her/them] as obtaining a Total Score T-score of [score], which falls in the [Mild/Moderate/Severe/Within Normal Limits] range. Subscale T-scores were as follows: Social Awareness ([score]); Social Cognition ([score]); Social Communication ([score]); Social Motivation ([score]); Restricted/Repetitive Behavior ([score]). The highest subscale scores were in the areas of [subscales], reflecting [rater]'s report of [brief description of most prominent concerns].

Cross-Informant — Concordant Elevation

SRS-2 data was collected from both [Student]'s [parent] (Total T = [score], [classification]) and [his/her/their] teacher (Total T = [score], [classification]). Both raters independently identified significant social impairment across home and school settings. The consistency of SRS-2 findings across informants is consistent with the pervasive pattern of social communication difficulties required for Autism Spectrum Disorder documentation under DSM-5 Criterion A. Elevated scores were particularly notable in the areas of [subscales], reflecting [brief description].

Cross-Informant — Discrepancy

[Student]'s [parent] rated [him/her/them] in the [classification] range (Total T = [score]), while [his/her/their] teacher's ratings fell in the [classification] range (Total T = [score]). This [X]-point discrepancy between home and school ratings may reflect [brief contextual explanation — e.g., the highly structured and scaffolded school environment reducing the visibility of social impairment, greater peer comparison demands at school, or the student's use of learned compensatory strategies that are more effortful and less sustainable in less predictable home and community settings]. Both perspectives are considered in the overall interpretation of [Student]'s social profile.

AU Context Language

Connecting SRS-2 to DSM-5 Criteria

SRS-2 subscale results reflect a profile consistent with Autism Spectrum Disorder. [Student]'s elevated Social Communication (T = [score]) and Social Motivation (T = [score]) scores reflect documented difficulties with pragmatic language, reciprocal social interaction, and initiating and sustaining peer relationships — corresponding to DSM-5 Criterion A deficits in social communication and interaction. [His/Her/Their] elevated Restricted/Repetitive Behavior score (T = [score]) reflects [rater]'s observations of [specific behaviors noted] — corresponding to DSM-5 Criterion B patterns. This subscale profile, considered alongside [other evaluation data], supports the documentation of an autism-consistent social and behavioral profile with adverse educational impact.

Masking — Within Normal Limits Despite AU Concerns

[Student]'s SRS-2 Total Score of [score] falls within the [Mild/Within Normal Limits] range. While this score does not reflect marked social impairment on this measure, it is interpreted in the context of [Student]'s history of significant effortful social compensation. [He/She/They] has demonstrated a pattern of masking — using learned social scripts and imitation to approximate neurotypical social behavior — which may suppress observable symptoms on rating scales relative to [his/her/their] actual functional impairment. Parent report, direct observation, and [other data sources] reflect social difficulties not fully captured by the SRS-2 Total Score alone, and the subscale profile — particularly [specific subscales] — remains consistent with autism-related social impairment.
