It’s important to understand that there isn’t a single medical test, such as a blood test or brain scan, that can definitively diagnose autism spectrum disorder (ASD). Instead, diagnosing autism spectrum disorder (ASD) is a comprehensive process. Experienced healthcare professionals reach an autism spectrum diagnosis through careful evaluation. This involves a detailed review of an individual’s developmental history and behavior. Professionals conduct interviews, observe the person directly, and gather insights from family members and caregivers. To aid in this complex process, they utilize standardized Autism Spectrum Diagnosis Tests and screening tools.
While only qualified health professionals can provide a formal autism spectrum diagnosis, various screening tools are available to help identify individuals who may exhibit autism symptoms. These tools are invaluable for parents, caregivers, and individuals themselves who are concerned about potential ASD. Early autism spectrum diagnosis tests and screening are crucial as they can significantly improve access to necessary services and support systems. This early access, in turn, can positively influence the long-term outcomes and quality of life for individuals on the autism spectrum.
The following sections outline several widely-used autism screening tools designed to identify potential ASD in both children and adults. It is important to remember that this is not an exhaustive list, and other assessment tools are available. Crucially, a positive result on any screening tool is not a diagnosis of autism. If a screening indicates a potential concern, it is essential to pursue a comprehensive diagnostic evaluation by a qualified healthcare professional specializing in autism spectrum diagnosis tests.
Available Autism Screening Tools
Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R)
Recommended for children aged 16 to 30 months

This tool serves as an initial autism spectrum diagnosis test, helping to flag potential developmental differences early on. Access the 2-minute screening questionnaire.
Social Attention and Communication Surveillance, Revised (SACS-R) and SACS-Preschool (SACS-PR) Tools
Designed for children aged 12 to 60 months
The Social Attention and Communication Surveillance, Revised (SACS-R) and its preschool version, SACS-PR, are robust autism screening tools. Developed by experts at La Trobe University, these tools are specifically designed to identify behavioral patterns characteristic of autism spectrum disorder in very young children, starting as early as 12 months and extending through preschool age. These autism spectrum diagnosis tests are intended for administration by trained professionals. This includes psychologists, early childhood educators, allied health professionals, and other qualified individuals who can accurately observe and interpret the child’s social communication behaviors. Further information about these tools can be found at the SACS-R and SACS-PR website.
Social Challenges Screening Questionnaire (SCSQ)
Intended for school-aged children
The Social Challenges Screening Questionnaire (SCSQ), developed by the Southwest Autism Research & Resource Center (SARRC), is a valuable 15-question tool. It is designed to be completed by parents, educators, and medical professionals who work with school-aged children. This questionnaire helps identify children who may exhibit symptoms consistent with what was previously known as Asperger syndrome, now categorized as level 1 ASD within the autism spectrum. The SCSQ serves as an autism spectrum diagnosis test for identifying social communication differences in older children. Take the Social Challenges Screening Questionnaire online.
Autism Spectrum Quotient (AQ) Test
Appropriate for individuals aged 16 years and older
The Autism Spectrum Quotient (AQ) Test is a self-administered questionnaire comprising 50 questions. This autism spectrum diagnosis test is designed to measure the degree of autistic traits in adolescents and adults aged 16 and above. It is suitable for individuals with an IQ over 80 and provides a quantitative measure of traits associated with autism. The AQ test is a useful self-assessment tool for adults who suspect they might be on the autism spectrum. Take the Autism Spectrum Quotient Test here.
