Understanding the RAADS-R Test: A Guide for Parents

Autism spectrum disorder is a condition that affects the way a person communicates and interacts with others. While the symptoms may differ from person to person, some common symptoms affect the majority of autistic individuals. Many individuals with autism have difficulty with social interactions, impairments in communication, intense interests in specific topics, or engage in fixed or repetitive behaviors.

Autism can be detected as early as 18 months or younger, and is often diagnosed in early childhood. One crucial aspect of helping individuals with autism is an appropriate diagnosis. This is the first step in getting them enrolled in high-quality and effective treatment. However, diagnosing autism can be complex, as it requires careful observation and assessment by trained healthcare professionals. In addition, symptoms of autism spectrum disorder are common with other possible diagnoses, so being able to differentiate between different disorders is absolutely necessary.

One tool that can aid in the diagnosis of autism spectrum disorder is the Ritvo Autism and Asperger Diagnostic Scale-Revised (RAADS-R). This assessment is a bit different from others in that most autism assessments are focused on diagnosing autism in early childhood.

There are many types of assessments (such as the M-CHAT, VB-MAPP, or FBA) that are completed by medical providers or by caregivers that are used to screen young kids, but most of these assessments cannot be used by older children, teens, or adults. The RAADS-R is designed to help clinicians and researchers assess the presence and severity of autism symptoms in adults. More specifically, this tool is used to aid in diagnosing autism spectrum disorder in individuals 16 years or older. It consists of eighty questions that ask about social interactions, communication, sensory sensitivities, repetitive behaviors, and other aspects of daily functioning.

The main purpose of this article is to inform parents about the RAADS-R test and its importance in understanding their child’s needs. Learning about the RAADS-R can help parents to gain a bit deeper insight into their child’s behaviors and preferences. Knowing more about their abilities, their levels of function, and their preferences can be a significant step towards understanding their child’s needs.

What is the RAADS-R Test?

As mentioned above, the RAADS-R is a questionnaire designed to assess the presence and severity of autism spectrum disorder symptoms in adults. Autism is often diagnosed in early childhood after a series of assessments and observations. As advanced as mental healthcare has progressed, there are still many instances of children who go through their childhood without receiving an autism diagnosis and grow into adulthood as undiagnosed autistic individuals. This can be due to many things: cultural differences, concerns with insurance coverage, differences in the presentation of symptoms in children (especially gender differences in ASD), and misdiagnoses, just to name a few possibilities.

Autism can be much harder to detect in adulthood due to overlapping symptoms and comorbidities with other disorders. Since it is harder to detect in adulthood, adults can be (and are often) easily misdiagnosed with anxiety, depression, ADHD, or other mental disorders. The RAADS was created to better diagnose autism in adulthood. The test was revised (hence the -R in RAADS-R) to further improve its reliability and validity.

The primary objective of the RAADS-R is to provide a standardized and reliable tool for assessing autism symptoms in adults. This assessment can be crucial in aiding the diagnostic process and guiding intervention planning. Individuals completing the RAADS-R can provide valuable information about their functioning and the symptoms they face as a result of ASD. The results can help to determine their strengths and areas of improvement, which is the first step in finding the appropriate interventions.

The RAADS-R consists of several components designed to evaluate different aspects of the symptoms of autism. One component focuses on diagnostic criteria. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) has a very clear-cut outline of what is required for an official diagnosis of autism spectrum disorder, and so there is a need for the RAADS-R to have a component that is specific to an accurate diagnosis. Another component involves a symptom assessment, asking individuals to rate the frequency and intensity of various ASD-related behaviors they experience.

This can help to determine the level of support that they may need or the degree to which their functioning is impacted by symptoms. Additionally, the questionnaire includes questions about childhood developmental history and current functioning to provide a comprehensive picture of an individual’s autistic traits. Since autism is often diagnosed and present in childhood, it is important to look at their past to get a better idea of their autism overall and how it has affected their lives.

Understanding the RAADS-R Criteria

RAADS-R criteria

The RAADS-R includes questions that can be broken down into 4 different categories that are directly related to the DSM-5 criteria for autism. The total scores for each category are added together to determine whether a person might have autism.

A score of 65 or more means that an autism diagnosis may be accurate, with 240 being the highest possible score.

With that being said, it is important to recognize that scoring above 64 does not necessarily mean that the individual has autism spectrum disorder. Further testing and assessments with healthcare professionals is often necessary to ensure that another diagnosis doesn’t better explain the symptoms. The four categories of the RAADS-R assessment are:

  • Social Relatedness.

    Questions regarding social relatedness assess things such as difficulties in understanding social cues, struggles with forming and maintaining relationships, and problems with engaging in reciprocal communication. In childhood, individuals may have learned to mask their symptoms related to social relatedness or may have been just labeled as ‘shy.’ This is typically the biggest area of concern for autistic individuals, and this is reflected in the RAADS-R. Most of the questions on the assessment fall into this category.

  • Language.

    This domain focuses on difficulties in verbal and nonverbal communication. This includes challenges in understanding and using language, atypical speech patterns, or difficulties with pragmatic language skills. This is different from social relatedness in that it is more tied to language and its usage directly, while social relatedness has more of a focus on connecting to others. Undiagnosed children who struggle with language may have been diagnosed with other speech-related disorders or labeled as shy. This domain takes up the smallest amount of questions on the RAADS-R assessment.

  • Sensory-motor.

    This domain addresses sensory sensitivities and motor coordination difficulties, which are commonly noted symptoms of autism. Autistic individuals can have a hypersensitivity or hypo-sensitivity to sensory stimuli (e.g., sounds, lights, textures, tastes). It’s important to note that neurotypical people can have similar types of sensitivities, however with autistic people, these sensitivities are more intense and impact functioning. This domain also includes the assessment of motor coordination challenges. This is the second-largest domain assessed by the RAADS-R.

  • Circumscribed interests.

    This domain of the RAADS-R evaluates the presence of intense, narrow interests or repetitive behaviors. People with autism may have an interest in a particular subject that would be described as intense or deep. They may have seemingly expert-level knowledge about a niche subject or want to talk about one particular subject far more than they want to talk about other subjects. Individuals may also report engaging in repetitive behaviors, routines, or rituals. These behaviors might include spinning, hand flapping, hair twirling, or otherwise repetitive behaviors that are self-stimulatory in nature. The routines or rituals are usually deeply engrained in the person’s daily life and can cause tremendous stress if the routine has to change for whatever reason.

The different domains addressed by the RAADS-R capture the core symptoms and behaviors that define autism spectrum disorder. By assessing them, clinicians can identify patterns of behavior consistent with autism and differentiate them from other conditions, which is especially crucial considering the high rates of misdiagnosis in adults. Accurate diagnosis is crucial for providing appropriate support.

The RAADS-R Test Process


Taking the RAADS-R test usually starts with a healthcare professional providing the questionnaire to the individual being assessed. The individual is then asked to read and respond to a series of questions that touch on any of the four domains mentioned earlier. The assessment will ask direct and indirect questions related to social interactions, communication abilities, sensory sensitivities, repetitive behaviors, and more.

Professional Guidance

During the assessment, healthcare professionals are responsible for guiding the person taking the test and ensuring that it is completed as accurately as possible. Accuracy in taking the assessment is essential for the test to be as reliable and accurate as possible for identifying autism. The professionals can also provide instructions on how to fill out the questionnaire and offer clarification as needed. This can be especially helpful if the questions are confusing or if the person’s first language isn’t English and they are unsure about what the question may be asking. Additionally, healthcare professionals review responses and interpret the results for the person, helping to inform diagnosis decisions and possible treatment planning.


Parents can expect the RAADS-R test to take around 20 minutes to an hour for their child to complete, although this is just a rough estimate. It’s ultimately up to their level of comprehension and pace while completing the test. Parents need to encourage their child to answer the questions to the best of their ability. Sometimes, with self-assessments, people feel more inclined to answer questions to better align with the expectations of others. This can skew results and make the results less reflective of actual functioning. Parents should be sure to stress the importance of honesty when taking the assessment.

Provide Additional Information

Additionally, parents may be asked to provide relevant information about their child’s developmental history and current functioning. Minimal preparation may be required before taking the exam, and parents should discuss this with healthcare providers before the assessment. A quiet and comfortable environment may be ideal to complete the RAADS-R.

What do The RAADS-R Results Mean?


As I mentioned before, a higher score on the RAADS-R indicates a higher likelihood for autism spectrum disorder, with a score higher than 64 indicating a high likelihood. The maximum score is 240. Higher scores indicate greater presence and severity of autistic traits and lower scores suggest fewer or milder symptoms. Healthcare professionals use these scores to help determine whether or not an individual meets the diagnostic criteria for autism spectrum disorder.

It’s important to note that RAADS-R results can vary widely across individuals and that the scores across the different domains may be different. Some individuals may score high across all domains and others may score higher in only certain domains. This is why the RAADS-R must be interpreted by a healthcare expert before assuming any type of diagnosis. The variations also do a wonderful job in getting a better image of the individual’s unique strengths, challenges, and support needs.

After receiving RAADS-R results, the next step is to discuss the findings with a healthcare professional. This is necessary to determine an official diagnosis, which is necessary before being able to develop interventions and supports. Possible services may include behavioral therapy, occupational therapy, or speech therapy.

The services recommended by healthcare providers will likely be related directly to the deficits that are highlighted by the results of the RAADS-R. For example, those with sensitivity concerns will more likely be recommended for occupational therapy, while those who struggle with language and communication may be referred to a speech-language pathologist.

The Significance of RAADS-R in Autism Diagnosis

While there are various assessment instruments used to help professionals diagnose autism spectrum disorder, the RAADS-R stands out for its focus on symptoms in adults. Nearly all other tools are designed for children or adolescents. Using these types of tests on adults is rarely accurate or reliable. Having a test that is specific to adults is important, especially since not all cases are diagnosed in childhood. Not all parents have their children tested for one reason or another, and the RAADS-R helps those children once they get older and can get tested. The RAADS-R was specifically created to capture the unique challenges faced by autistic adults.

The RAADS-R also offers several advantages. For instance, its emphasis on self-reporting makes it particularly suitable for individuals who may require lesser support and who may have greater insight into their own experiences. This is one of the very few autism assessments that is based on self-reporting. For other assessments, there is a heavier focus on outside observation and input from others (e.g., caregivers, teachers, etc.).

There are children whose autism wasn’t diagnosed earlier in life because their symptoms were more covert or they were able to better hide their symptoms from others. Reliance on outsider input and observation can easily miss symptoms that a child may be experiencing in cases like this. Being able to self-report symptoms makes these individuals less likely to fall through the cracks.

In addition, the RAADS-R is a relatively quick assessment. For some autism assessments, long periods of observation are required. Not only that, but all symptoms may not be observed during an observation. For example, if a child were sensitive to loud noises, an observation that didn’t include a loud noise can easily miss out on observing that symptom. The RAADS-R is quick to complete and asks enough questions to avoid missing out on possible symptoms of autism.

The RAADS-R certainly has its benefits, but it also comes with a list of limitations that should be seriously considered before deciding to get an assessment. First and foremost, its reliance on self-reporting can be challenging for individuals with limited communication abilities or cognitive impairments. Self-reporting can also be a double-edged sword in that it allows individuals to provide information about their personal experiences and challenges, which can be especially helpful for those with more covert symptoms.

However, relying solely on self-reporting isn’t always reliable. Answers can very easily be influenced by mood, cognitive biases, level of self-awareness regarding certain behaviors, perceived expectations from loved ones, warmth of the testing room, nervousness from the presence of healthcare experts during the assessment, level of hunger, and almost anything else.

Additionally, while the RAADS-R provides valuable insights, it does not replace a comprehensive evaluation conducted by qualified healthcare professionals. The results of a RAADS-R test aren’t enough. Parents should view the RAADS-R results as one part of the overall package and seek further evaluation from healthcare providers as needed.

Supporting Your Child Post-Diagnosis


Since the RAADS-R gathers a lot of information regarding the different domains, the findings can be incredibly helpful to parents wanting to be more supportive of their child’s needs. The scores give a more direct look at the things that their child may struggle with. Using this information, parents can better support them in their home environments, learn more about the possible interventions that may be beneficial for them, and understand how exactly their symptoms impact their daily lives.

Another way for parents to support their child beyond the specific findings of the RAADS-R is to learn more about autism and how it affects them. Understanding their strengths, struggles, and what bothers them can help make things easier for them at home and at school. Parents can benefit from learning common tips for communicating with autistic individuals, such as creating a regular routine and being clear when giving instructions.

Parental support may not always be enough support, so getting help from lots of different experts can make a big difference. Talking to therapists, teachers, and doctors can help get a better picture of what the child needs to best support them in their daily life. There are an infinite amount of resources and support systems available to parents, so long as they know where to look. Talking to healthcare professionals is an incredible start. They will be able to point parents in the right direction in finding the types of support and resources they may benefit from.


What is a normal RAADS-R score?

Scores can vary widely for both autistic individuals and neurotypical individuals, so it could be argued that there is no “normal” RAADS-R score. The scores range from 0 to 240, with a higher score meaning that autism is more likely. With that being said, it is possible that autistic individuals have lower scores, and it is possible for non-autistic individuals to score higher. This is why talking to a healthcare provider is important. With that being said, neurotypical individuals typically have a score that falls below 65, and higher than that indicates that further evaluation may be necessary.

Can you score high on the RAADS test and not be autistic?

Yes! It is very possible to score high on the RAADS-R test and not have autism. The RAADS-R assesses a range of traits associated with ASD, but high scores can also be influenced by other factors. Individuals with other disorders, such as anxiety or depression, who take the assessment may end up with a higher score. People without such disorders may also score higher, depending on their mood or personality. Additionally, individuals with certain developmental or psychiatric conditions may exhibit symptoms similar to autism, leading to higher scores. Therefore, while a high score on the RAADS-R may suggest the presence of autism, a comprehensive evaluation by qualified medical professionals is necessary.

Is RAADS-r an official test?

The RAADS-R is not an official diagnostic test in itself. Instead, it serves as one part of a comprehensive diagnostic evaluation. An autism diagnosis typically requires a thorough assessment by qualified medical professionals who consider multiple sources of information (like RAADS-R results, clinical observations, developmental history, and other diagnostic criteria outlined in the DSM-5). Simply taking the assessment isn’t enough for a diagnosis.

What is the lowest score on the RAADS test?

Technically, the lowest score someone can receive on the RAADS-R assessment is a 0, although the odds of scoring a 0 are pretty slim. Neurotypical people who have taken the exam have typically have scores of 64 or less, but it’s more than likely that they will have at least some points. Some of the questions on the assessment are incredibly specific to autism, while others may also touch on personal preferences or personalities.


The RAADS-R is a great start for parents who want to test their older child for autism spectrum disorder. It offers insight into various aspects of autism and makes the next steps after diagnosis much clearer. Completing the RAADS-R lets individuals and their families gain a better understanding of strengths and challenges, which paves the way for individualized interventions that will best work for the autistic individual. If parents believe that their child is showing signs of autism spectrum disorder, they should most definitely seek out professional advice and work with their medical providers to determine the next steps.
