As more information related to autism spectrum disorder (ASD) is released, more adults may recognize autistic traits in themselves. Recognizing these traits may prompt a person to seek an autism test online or search for free autism screening resources. While these tools may be quick and free to use, a formal assessment can only be administered by a qualified healthcare provider.
While a professional evaluation is required for a formal diagnosis of autism spectrum disorder, free autism tests can be used as a screening tool for individuals who believe they may be living with autism. There may be several considerations to think about before choosing a free diagnostic tool or online test. In this article, we will explore online autism testing options and examine their effectiveness.

What are free autism tests for adults?
Free autismtests for adults are self-assessment tools designed to help individuals explore whether they might have traits commonly associated with autism spectrum disorder. These tests are often available online and take the form of multiple-choice questionnaires that ask about social interaction, sensory sensitivities, routines, and communication patterns. Common assessments include the Autism Spectrum Quotient (AQ), Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R), and the Camouflaging Autistic Traits Questionnaire (CAT-Q).
Autism Spectrum Quotient
The Autism Spectrum Quotient, or AQ, is a commonly used and recognized self-assessment tool for identifying autistic traits in adults. The AQ consists of 50 questions, each targeting a specific cognitive, behavioral, or social function. Research shows that the AQ test may be an effective way to preliminarily identify the potential of ASD. However, a professional evaluation is required for an official diagnosis.
Ritvo Autism Asperger Diagnostic Scale - Revised
The Ritvo Autism Asperger Diagnostic Scale - Revised (RAADS-R) is a more in-depth autism screening tool originally developed to help clinicians identify autism spectrum disorder in adults. It may be particularly useful for those whose symptoms went unnoticed during childhood. The RAADS-R is retrospective, which means that it asks about both current behavior and childhood history, which can provide a broader picture of lifelong patterns.
Camouflaging Autistic Traits Questionnaire
The Camouflaging Autistic Traits Questionnaire (CAT-Q) is a newer self-assessment tool that sheds light on something many late-diagnosed or self-identifying autistic adults experience: masking. Masking generally refers to the efforts an individual makes to hide or camouflage symptoms of autism. The CAT-Q consists of 25 statements and is divided into three key dimensions, which include compensation, masking, and assimilation.
What autism tests can and cannot tell you
Free autism tests can be a resource for individuals who may notice patterns of behavior in themselves that seem to align with autism spectrum disorder symptoms. These tests can be a starting point in determining whether further investigation may be needed. A high score or strong identification with certain traits may suggest it's worth pursuing a professional assessment, especially if those traits impact a person’s daily life.
These tests are only designed to screen for potential autism symptoms and not other developmental disorders that may have similar symptoms or impacts. This could lead a person to pursue treatment for ASD when there is a different underlying disorder present.
Is the Autism Spectrum Quotient accurate in screening for autistic traits?
One of the most popular free online tests is the Autism Spectrum Quotient, which may be relatively accurate at screening for autistic traits. It may be useful mostly in a preliminary capacity, with around 47% of individuals who test positive using the AQ test meeting the criteria for an ASD diagnosis. While this may not be extremely accurate, the AQ can be used to prompt an individual to seek professional evaluation.
The accuracy of the AQ test may improve when taken alongside other ASD tests, such as the RAADS-R and CAT-Q. With each of these tests, there may be limitations due to self-reporting bias, in which a person intentionally answers a certain way to get a desired result. Although no self-evaluation is perfect, the AQ has been studied in clinical and academic contexts and is considered one of the more valid tools available for adult self-screening.

Common red flags for autism tests
While some online autism tests are grounded in research and clinical practice, not all are reliable or ethical. Some may be misleading or rely on oversimplified questions, while others may have very strong interests in upselling treatments or further evaluations. Understanding the red flags of free online testing may help a person choose reputable platforms that can provide more reliable results.
Promising an autism diagnosis after screening tests
One major red flag when considering a free online autism test is if the test promises to make a diagnosis after screening. An ASD diagnosis cannot be provided after a single online test and requires connecting with a professional who has the expertise to evaluate potential autism symptoms. A doctor or mental health professional usually considers a person’s complete developmental history, along with current signs and symptoms, to make a diagnosis.
Tests that upsell treatment for autistic traits
Another red flag may be if an online testing company attempts to upsell users for the treatment of autism or autistic traits. This may create a conflict of interest as there could be an incentive to show people that traits exist, even if they do not. Additionally, it may be best to avoid online tests if results can only be accessed after paying a fee. Ethical autism assessments do not gatekeep a person’s results.
Signs and symptoms of autism
It may be possible to identify signs and symptoms of autism in adults without taking a free online screening. Common signs and symptoms can include various social signs, repetitive behaviors, and cognitive impacts. These signs can vary from person to person in both type and severity. Understanding what to look for can help a person get the support they deserve.
Social signs
In adults, social signs may include difficulty reading social situations or discerning cues in a social setting. A person with ASD may find it challenging to communicate, especially when making small talk or expressing emotions. There may also be a preference for deep and structured conversations rather than superficial chats.
Repetitive behaviors and routines
Individuals living with autism may prefer structured daily routines rather than spontaneity. Changes in routine can lead to general unease, anxiety, and distress for people living with ASD. Additionally, a person living with autism may engage in repetitive behaviors, including fidgeting or tapping, to regulate sensory input.
Cognitive and emotional signs
In addition to social signs and repetitive behaviors, a person living with ASD may experience cognitive and emotional symptoms. Individuals may engage in deep focus on a particular topic of interest and find it challenging to multitask. They may also experience a high sensitivity to rejection or criticism, which can create challenges at school or work.
Getting an autism diagnosis
Many adults may not discover that they have been living with autism until later in life, often after years of struggling with challenges like social burnout and sensory overload. Whether a person has taken an online test or not, seeking a formal assessment can be a good first step for individuals experiencing traits of autism.
The diagnostic process usually involves several steps that can help a mental health professional determine whether a person meets the criteria for ASD as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). The professional may incorporate tests, including the AQ, RAADS-R, and CAT-Q, to preliminarily identify traits. Additionally, they may incorporate psychological or cognitive testing and clinical observations to make a diagnosis.

Connecting with a mental health professional
Connecting with a mental health professional may be an important step for individuals living with autistic traits. A therapist may evaluate, diagnose, and treat ASD using various tools and techniques. They may also be able to identify any co-occurring mental health conditions.
It can be uncomfortable for people experiencing autistic traits, such as challenges with social situations, to attend therapy sessions at a brick-and-mortar office. Online therapy can take place from any location with an internet connection and a personal device, which allows people to attend therapy from a setting where they feel comfortable and at ease. Online therapy platforms can also make it easier for individuals to connect with professionals who have experience working with people with autism spectrum disorder.
Online therapy can be an effective way to manage the impacts of autism, according to a 2021 study. An online therapist may incorporate coaching and skills to improve communication and help a person manage their symptoms.
Takeaway
How do I get tested for autism as an adult?
There are a few avenues you can take if you’d like to pursue an autism diagnosis. You can start by speaking to your primary care provider, who can refer you to a specialist, or you can seek out a psychologist, psychiatrist, or social worker who has experience working with Autistic people. You may be able to find phone numbers and other contact information for professionals in your area online.
What is the most accurate autism test for adults?
An autism diagnosis usually requires multiple tests. However, one of the most common is the Autism Diagnostic Interview - Revised (ADI-R). This is frequently used in conjunction with other tests to collect evidence for an autism diagnosis.
What can be mistaken for adult autism?
A few conditions that can be mistaken for adult autism include various developmental disorders, sensory processing issues, obsessive-compulsive disorder, social anxiety disorder, and schizophrenia. Many of these disorders have similar or overlapping symptoms, so it can be crucial to seek a professional diagnosis rather than attempting to self-diagnose.
How much does an adult autism assessment cost?
The cost of an adult autism assessment can vary greatly but may range from $1000 to $2000. Depending on your insurance coverage, the out-of-pocket cost may be much lower.
Is it worth getting an autism diagnosis as an adult?
Whether or not it is worth getting an autism diagnosis as an adult is subjective and varies from person to person. Some people may find it helpful to have a verified explanation of the symptoms they’ve experienced throughout their lives, for example. Meanwhile, others may have reached a point where they have already determined strategies to cope with their symptoms and don’t feel the need to seek a diagnosis. Still, a diagnosis can be helpful for young women and men who want to seek further treatment and intervention.
What does undiagnosed high-functioning autism look like in adults?
As a person’s appearance cannot determine whether they have autism, undiagnosed autism doesn’t necessarily have a particular “look.” However, level one autism spectrum disorder, which has the lowest support needs, can present with symptoms like the following:
- Difficulty interpreting social cues, body language, facial expressions, and other people’s intentions
- A strong adherence to specific routines and a need to carefully plan activities
- Stimming behavior or similar common compulsions
- Becoming strongly absorbed in specific topics or having intense interests
- Struggling to maintain friendships and/or employment
In most cases, these symptoms go back to when the individuals were young children. It can be important to note that autism is a spectrum, and every Autistic person is an individual with their own unique strengths and challenges.
What is the biggest predictor of autism?
The most significant predictor of autism may be having a close relative with autism spectrum disorder. Autism is hereditary, with approximately 80% of cases being linked to inherited genetic mutations.
Does Blue Cross Blue Shield cover autism testing for adults?
Blue Cross Blue Shield insurance plans may cover autism testing for adults in some cases. In general, the testing must be ordered by a mental health professional and deemed medically necessary.
What is borderline autism in adults?
“Borderline autism” is not a clinical term or an official diagnosis. Instead, it usually refers to people who display mild (sub-diagnostic threshold) symptoms of autism spectrum disorder.
What is the mirror test for autism?
While the mirror test is not used to diagnose autism, it generally involves putting a mark on a person’s face without their knowledge and then observing their reaction when they see their face in the mirror. If the individual’s response is to touch the mark on their face, that typically shows a certain level of self-recognition and self-awareness. It’s thought that some Autistic individuals experience delayed self-recognition.
