What is a Screening Test?

Curious clients often start by taking one or more of the on-line screening tests listed below (not definitive tests).

Screening tests are initial assessments designed to identify individuals who might be autistic or an ADHD'er. These tests are typically brief and aim to quickly determine whether a more comprehensive evaluation is necessary. Screening tests are not diagnostic tools but rather serve to flag potential developmental issues or ASD characteristics.

Screener says "low" or "no"

If the results of the screening tests below indicate no or a very low indication of autism or ADHD as compared to the average for the population, you may decide that an in-depth evaluation is not warranted.

Screener says "possible"

However, if the screening tests indicate that ASD and/or ADHD is possible, you should strongly consider an in-depth evaluation.  The first step is to fill out our contact form so you can book a free consult with us.



Please be aware that these screening tests:

  • are limited in depth and scope,

  • may limit the amount that you learn about yourself,

  • are insufficient for a in-depth assessment, and

  • are not a replacement for an assessment by a caring and well-trained clinician.


  • 1. Autism Spectrum Quotient (AQ) Test
    • Click HERE to take test
    • The most common screener for Autism. Score is based on the number of Autistic traits.  

      • Created for autistic adults without co-occurring intellectual disabilities. 

      • Less effective at screening those with highly developed masking skills and autistic individuals who are extroverted and/or imaginative.

      • 50 Questions

      • Scoring:

        • a result of 26 or higher (50 points total) indicates the possibility of Autism

        • 80% of autistic people score 32 or higher

        • Most non-autistic males score 17 on average

        • Most non-autistic females score 15 on average

  • 2. Ritvo Autism & Asperger Diagnostic Scale (RAADS-14)
    • Click HERE to take test

    • Higher emphasis on internal experiences than outward behaviors. Effective for distinguishing Autism from other conditions which may be confused for autism (Bipolar, PTSD, Social Anxiety).

      • 14 Questions

      • Scoring:

        • 14 and above out of possible 42 are indicative of possible Autism

  • 3. Modified Girls Questionnaire for Autism Spectrum Condition (GQ-ASC) - Scale for Adult Women
    • Click HERE to take test

    • This screening questionnaire is designed to identify behaviors and abilities in women that are associated with autism.

    • 21 Questions

    • A total score of greater than 56 indicates a high level of autistic traits; sensitive to 80% of cases.

  • 4. Camouflaging Autistic Traits Questionnaire (CAT-Q)
    • Click HERE to take test

    • The CAT-Q measures the level of Autistic camouflaging (masking, social compensation, and assimilation).

    • 25 Questions

    • Identifies Autistic individuals who do not meet diagnostic criteria for autism on other tests due to masking autistic traits. 

    • The total score ranges from 25–175 with scores 100 or above indicating camouflage of autistic traits. 

    • Subscale scores include:

      • Compensation — Strategies used to actively compensate for difficulties in social situations. Examples: copying body language and facialexpressions, learning social cues from movies and books.

      • Masking — Strategies used to hide autistic characteristics or portray a nonautistic persona. Examples: adjusting face and body to appear confident and/or relaxed, forcing eye contact.

      • Assimilation — Strategies used to try to fit in with others in social situations. Examples: Putting on an act, avoiding or forcing interactions with others. 

    • Risk: Factors other than Autism may cause a person to have a high masking score; therefore, CAT-Q may have a higher rate of false positives. 



  • Autism Spectrum Screening Questionnaire (ASSQ) 

    • The original ASSQ consists of 27 items for a maximum score of 54 points. 

    • The higher the point total, the greater the likelihood that you show signs of autism spectrum disorder.

    • Score of 51 or higher on the ASSQ indicates possibility of ASD and further assessment is recommended.
