- The DSM-5 defines three autism levels based on how much support a person needs in social communication and restricted, repetitive behaviours, not on intelligence or overall ability.
- Approximately 26.7% of autistic individuals meet criteria for Level 3, which requires very substantial support across both diagnostic domains, according to a 2025 ADDM Network study (PubMed ID: 41872583).
- Autism levels are not fixed: a 2023 peer-reviewed study found that roughly 51 to 54% of autistic children show a change in DSM-5 severity level over time, with about 27% showing a decrease.
- In Dubai, a child's DSM-5 severity level directly shapes the type of school support a KHDA-compliant school must provide, from differentiated teaching at Level 1 to one-to-one aide provision or specialist placement at Level 3.
- Level assignments in Dubai are made by DHA-licensed clinicians using structured tools such as the ADOS-2 and ADI-R; the level must be documented in the assessment report for it to be accepted by Dubai schools and the KHDA.
The World Health Organization estimates that 1 in 100 children globally meet criteria for autism spectrum disorder, while the US Centers for Disease Control reports a figure closer to 1 in 31 in its most recent 2022/2023 data. Within Dubai, the DHA's own Clinical Practice Guidelines for Autism Spectrum Disorder acknowledge that local prevalence figures remain unknown and recommend using international estimates in the interim. What we do know is that 69.1% of cases registered with the Dubai Autism Centre involve expatriate children, which underlines just how directly this topic touches the city's international families.
If your child has recently received an autism diagnosis in Dubai, you were almost certainly given a level: Level 1, Level 2, or Level 3. Many parents leave that appointment knowing the number but not what it actually means for how their child learns, plays, communicates, or fits into a Dubai school. This article addresses exactly that. It assumes your child has already been assessed. If you are still at the stage of understanding whether an autism assessment is the right next step, our guide to autism assessment for children in Dubai covers the diagnostic process from start to finish.
Here, we focus entirely on what happens after the diagnosis: what each level describes, what it means in daily life, how it connects to school support under Dubai's KHDA framework, and what to do if your child's needs seem to have changed since the original assessment.
What are autism levels and why did DSM-5 introduce them?
Before 2013, the diagnostic landscape for autism was split into several separate categories: autistic disorder, Asperger's syndrome, pervasive developmental disorder not otherwise specified (PDD-NOS), and childhood disintegrative disorder. Each label carried different social weight, different clinical implications, and, in practice, wildly inconsistent application across clinicians and settings. A child diagnosed with Asperger's in one country might have received a PDD-NOS diagnosis in another, even with identical profiles.
The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, the DSM-5, collapsed all of these into a single diagnosis: autism spectrum disorder. To replace the old categorical distinctions, the DSM-5 introduced a severity rating system based on two core diagnostic domains.
The first domain covers social communication and social interaction: how a person initiates and responds to social overtures, whether they use and understand nonverbal communication, and how they form and maintain relationships. The second domain covers restricted, repetitive behaviours, interests, or activities: the presence of inflexible routines, sensory sensitivities, highly focused or intense interests, and repetitive motor movements.
Each domain is rated separately on a three-point scale. The overall level assigned to a person is determined by the area of greatest support need. So a child who requires moderate support in social communication but very substantial support for managing restrictive and repetitive behaviours would be assigned Level 3 overall. The level reflects need, not ability, and not fixed potential.
One further point worth making at the outset: the DSM-5 level is a clinical snapshot taken at a particular point in time. It describes the amount of support a child needs now, informed by structured assessment. It does not predict the ceiling of what they can achieve, and it does not remain static throughout childhood. More on that in a later section.
What autism levels 1, 2 and 3 actually mean for your child's day-to-day life
Clinical definitions matter, but what most parents need is a concrete picture of what each level looks like at home, at school, and in social situations. The descriptions below draw on DSM-5 criteria and the clinical framing we use at CAYA World during post-assessment feedback sessions.
Level 1: Requiring support
A child at Level 1 can speak in full sentences and engage in conversation, but social interactions often feel effortful or one-sided. They may struggle to initiate interactions with peers, miss unspoken social rules, or have difficulty maintaining friendships beyond shared activities. They may become noticeably distressed when routines are disrupted, even if they can manage the disruption when prepared. In a mainstream classroom, a Level 1 child might follow lessons well academically but find unstructured times such as break or group work genuinely hard to navigate.
At home, parents often describe a child who is articulate, curious, and clearly capable, yet periodically melts down over what seem like small changes. The support need at Level 1 is real, even if the child can mask it effectively in some settings for stretches of time. Masking, which involves effortfully suppressing autistic traits to appear more neurotypical, is associated with significant anxiety and fatigue, particularly in girls and in academically able children.
Level 2: Requiring substantial support
At Level 2, deficits in social communication are more apparent even with supports in place. Speech may be limited to functional phrases, conversations may be mostly initiated by the child around preferred topics, or nonverbal communication may be noticeably reduced. Responses to social overtures from others can be atypical or reduced in frequency. Repetitive behaviours are obvious enough that they cause difficulty functioning across more than one setting, and the child shows marked distress when routines are altered, often requiring significant co-regulation from an adult.
In a Dubai school context, a Level 2 child is likely to need structured small-group intervention, a Learning Support Teacher, and often a Teaching Assistant to access the curriculum and manage transitions through the school day. Without those supports, the academic and social gap tends to widen.
Level 3: Requiring very substantial support
Level 3 represents the most intensive support needs across both diagnostic domains. Verbal communication may be very limited or absent, or present but not consistently functional for social exchange. Initiating interactions is rare. Repetitive behaviours significantly interfere with functioning across all settings. Extreme distress in response to environmental change, including sound, light, transitions, and unpredictability, is common. A 2025 ADDM Network study found that approximately 26.7% of autistic individuals meet criteria for what the authors termed "profound autism", broadly corresponding to Level 3 on the DSM-5 severity scale. These children typically require highly individualised educational programmes and often one-to-one support for the majority of the school day.
At CAYA World, when we deliver feedback to families of children assessed at Level 3, we spend considerable time mapping the specific support plan alongside the level itself. The number alone tells only part of the story. The accompanying clinical formulation, which describes the child's sensory profile, communication strengths, co-occurring conditions, and family context, is what actually drives the support recommendations.
Why "high-functioning" and "low-functioning" labels are no longer used
You may hear the terms "high-functioning autism" and "low-functioning autism" from other parents, from older clinical reports, or occasionally from professionals who trained before the DSM-5 was published. Understanding why these terms have been largely abandoned helps explain what the level system is trying to do instead.
The core problem with functioning labels is that they conflate very different dimensions of a person's profile into a single adjective. A child described as "high-functioning" because they are verbal and academically able may have profound anxiety, an inability to tolerate sensory environments, and extreme difficulty with peer relationships. Calling them "high-functioning" obscures the genuine support needs they carry, which often means those needs go unaddressed. Conversely, a child described as "low-functioning" because their verbal communication is limited may have strong nonverbal reasoning, clear preferences, and substantial capacity for learning through adapted methods, none of which the label acknowledges.
A 2024 PubMed study examining the use of functioning labels confirmed that high/low functioning designations do not accurately predict capabilities across different domains of a person's life. The autistic community, researchers, and clinical bodies have broadly moved away from these terms because they flatten a complex profile into a single dimension that serves neither the individual nor the people supporting them.
DSM-5 levels attempt something more precise: they describe support needs in specific domains, not global ability. A clinician assigning Level 2 is saying that this child needs substantial support in social communication and substantial support managing repetitive behaviours. They are not making a statement about the child's intellectual potential, emotional depth, or long-term prognosis.
At CAYA World, we avoid functioning labels entirely in our reports and in verbal feedback to families. When parents ask whether their child is "mild" or "severe," we redirect the conversation toward: what does your child need support with, when, and in which environments? That framing produces a more useful picture than any single-word descriptor.
It is also worth noting that the level system itself is not without critics. Some researchers argue that a three-point scale still oversimplifies a genuinely multidimensional profile. Current clinical consensus, including the DHA's own practice guidelines, continues to use DSM-5 levels as the standard for diagnostic reporting in Dubai, but clinicians should and do supplement the level with a detailed profile.
How does a clinician determine an autism level during assessment in Dubai?
The level assigned at the end of an assessment is not a guess or a general impression. It follows from structured observation and validated measurement tools applied across a standardised protocol. For families who went through the assessment process at a DHA-licensed clinic in Dubai, the core tools most likely used were the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) and, where a developmental history was gathered from parents, the Autism Diagnostic Interview, Revised (ADI-R).
The ADOS-2 involves a trained examiner conducting a series of structured and semi-structured activities with the child, designed to elicit social communication behaviours in a controlled way. The child's responses are coded, and the codes map onto comparison scores calibrated for age and language level. The ADI-R captures the developmental history through a detailed parent interview covering language development, social development, and the onset of repetitive behaviours from early childhood.
Together, these tools produce scores across both DSM-5 diagnostic domains. The clinician integrates those scores with their direct observation, any cognitive or adaptive behaviour testing, school reports, and developmental history to reach a diagnostic formulation. The severity level is then assigned based on where the child's profile sits across those two domains at the time of assessment.
In Dubai specifically, the assessment report must document the DSM-5 severity level and must include the assessing clinician's DHA licence number for it to be accepted by KHDA-compliant schools and for referral pathways within the DHA system. A report that assigns a diagnosis without specifying the level, or that has been produced outside a DHA-licensed context, may not be accepted for school accommodation purposes. Families new to Dubai who arrive with an existing diagnosis from another country sometimes need a supplementary report or at minimum a local clinician's review to meet these documentation requirements.
At CAYA World, our autism assessment in Dubai uses the ADOS-2 alongside cognitive and adaptive behaviour measures where clinically indicated, and our reports are formatted to meet DHA and KHDA documentation requirements. Dr. Nour Al Ghriwati oversees the assessment process, and parents receive a detailed written report plus a dedicated feedback session.

Does an autism level stay the same, or can it change over time?
This is one of the questions parents ask most often after receiving a diagnosis, and the honest clinical answer is: it can change, and for a meaningful proportion of children, it does.
A 2023 peer-reviewed study found that approximately 51 to 54% of autistic children showed a change in DSM-5 severity level over time. Around 27% of children showed a decrease in severity level, 24% showed an increase, and 49% remained stable. Change in either direction is therefore genuinely common, not exceptional.
Earlier data from UC Davis MIND Institute research published in 2020 found that nearly 30% of young children showed less severe autism symptoms at age 6 compared to age 3, with higher IQ identified as a significant predictor of symptom reduction. Early, intensive intervention is consistently associated with improved outcomes across social communication and adaptive behaviour, even when the underlying diagnosis and core neurological profile remain unchanged.
Several factors influence whether a child's level changes over time. Access to targeted intervention, the presence of co-occurring conditions such as anxiety, ADHD, or language delay, the child's cognitive profile, and environmental factors including school quality and family support all play a role. A child who receives structured speech and language therapy, social communication intervention, and appropriate school support from an early age is more likely to show a reduction in support needs over time than a child who does not receive these services.
It is important to understand what "change in level" does and does not mean. A decrease in DSM-5 severity level does not mean the autism has resolved or that the child is neurotypical. It means that the amount of support they require in the two diagnostic domains has reduced. The child is still autistic. Their sensory sensitivities, social processing style, and tendency toward focused interests remain part of their profile. What changes is the level of scaffolding they need to function well in their daily environment.
A Level 2 child who receives excellent early intervention and moves to Level 1 at a re-assessment two years later has made genuine, meaningful progress. That progress should be celebrated. It should also prompt a reassessment of the support plan: Level 1 needs differ from Level 2 needs, and the school support package should reflect the updated picture.
At CAYA World, we recommend review assessments when there has been a meaningful shift in presentation, when the child is transitioning to a new school phase, or when the current support package no longer seems to match the child's day-to-day functioning. Dr. Nour Al Ghriwati and our team can advise on the appropriate timing and format for a re-assessment based on the child's history and current profile.
What do autism levels mean for school placement and support in Dubai?
Dubai's KHDA Inclusive Education Policy classifies all autistic students as Students of Determination and legally prohibits schools from refusing admission solely on the basis of an ASD diagnosis, regardless of the child's severity level. This is one of the more progressive elements of the UAE's regulatory framework for inclusion, and it matters practically: a school cannot turn away a Level 3 child simply because they are Level 3.
What the level does shape, very directly, is the type and intensity of support the school is expected to provide. In practice, the relationship between level and school support works roughly as follows.
Level 1 and school support
A child at Level 1 typically qualifies for differentiated teaching within a mainstream classroom. This might include modified instructions, additional processing time, flexible seating arrangements, and social skills support provided in small groups. The child is expected to access the general curriculum alongside typically developing peers, with adjustments made at the classroom level by the class teacher and the school's Learning Support department.
Level 2 and school support
At Level 2, small-group intervention becomes the expected standard. This typically involves withdrawal sessions with a Learning Support Teacher for targeted academic or communication work, Teaching Assistant support during parts of the school day, a formal Individual Education Plan (IEP), and structured transition support between activities and settings. The school's Special Educational Needs Coordinator, known in Dubai's private school system as the SENCO or Inclusion Lead, should be actively involved in reviewing the IEP termly.
Level 3 and school support
Level 3 typically triggers a significantly more individualised provision. This can include one-to-one Teaching Assistant support for the majority of the school day, a heavily adapted curriculum, access to a specialist resource base or inclusion unit within a mainstream school, or in some cases, referral to a specialist educational setting. The Dubai Autism Centre and other specialist providers in the emirate serve children whose needs cannot be met within a mainstream school environment, even with substantial support.
The quality of inclusion provision varies meaningfully between Dubai's private schools. In the 2023/24 academic year, 76% of Dubai private schools were rated Good or higher for inclusion, with 27 schools achieving an Outstanding rating from the KHDA. That leaves a substantial minority where Level 2 and Level 3 provision may not meet the policy standard on paper. Families navigating school choice for a child with a Level 2 or Level 3 diagnosis benefit from reviewing individual school inspection reports and from requesting a meeting with the SENCO before placement, not after.
The KHDA also requires that assessment reports submitted to schools specify the DSM-5 severity level and include the assessing clinician's DHA licence number. A report without these elements may be queried by the school's administration and may delay the IEP process. Families who received their child's diagnosis overseas should confirm whether their report meets Dubai's documentation requirements before enrolling.
If your child has a diagnosis and you are working through what it means for their school in Dubai, our article on communicating your child's autism diagnosis to Dubai schools covers practical strategies for navigating the KHDA inclusion system, IEP meetings, and how to advocate effectively with your child's school.
Frequently Asked Questions About Autism Levels in Dubai
Level 1 means your child requires support, not that their autism is trivial or that their challenges are minor. Many children at Level 1 experience significant anxiety, exhaustion from masking in social situations, and real difficulty with peer relationships, even if these struggles are less visible than those of children at higher levels. The level reflects support need in the two DSM-5 diagnostic domains; it does not capture the full weight of what your child carries. A Level 1 child who is struggling deserves the same clinical attention and structured support as any other level.
Yes, this is clinically well-documented. A 2023 peer-reviewed study found that around 27% of autistic children showed a decrease in severity level over time. Early intervention targeting social communication, language development, and adaptive behaviour is consistently associated with reduced support needs across development. Reduction in level does not mean the autism has resolved. It means the amount of scaffolding your child needs has decreased, which is a meaningful and genuinely positive outcome. Re-assessment by a DHA-licensed clinician is required to formally update the level on your child's diagnostic report.
Under Dubai's KHDA Inclusive Education Policy, schools regulated by the KHDA cannot refuse admission to a child solely because they have an autism diagnosis, regardless of level. However, the level does shape the type of support the school is expected to provide, from differentiated teaching at Level 1 to one-to-one aide provision at Level 3. In practice, not every mainstream school has the capacity to meet Level 3 needs, and some children are better served by specialist settings. The level on your report also affects which schools can realistically accommodate your child's needs well, and reviewing KHDA inspection reports for inclusion ratings before choosing a school is strongly advisable.
The DSM-5 was published in 2013, but clinical language shifts more slowly than diagnostic manuals. Some clinicians trained before 2013 use the old terminology out of habit, and some families find it more intuitive. The term persists in everyday conversation partly because it feels descriptive. The reason it has been formally retired is that it conflates very different dimensions of a person's profile into a single adjective that is neither accurate nor useful for planning support. A child described as "high-functioning" may have profound anxiety and sensory challenges that go unaddressed because the label implies they are managing fine. DSM-5 levels are more precise because they describe support needs in specific domains.
Not every change in needs requires a formal re-assessment, but a full re-assessment is advisable when there has been a meaningful and sustained shift in your child's presentation, when they are transitioning to a new school phase such as moving from primary to secondary, or when the current support plan no longer matches their functioning. In Dubai, if you need an updated report for KHDA school support documentation or for DHA referral pathways, the report must reflect a current, formally documented assessment by a DHA-licensed clinician. A brief clinical review can sometimes clarify whether a full re-assessment is warranted or whether a letter from the current treating clinician is sufficient.
