3 Levels of Autism

3 levels of autism

Navigating the diverse spectrum of Autism Spectrum Disorder (ASD), individuals are categorized into three levels of autism based on the severity of their symptoms and required support. Level 1 reflects mild difficulties, level 2 indicates marked impairments, and level 3 signifies severe challenges. 

Importantly, the spectrum is dynamic, and individuals may fluctuate between levels based on various factors. Some may even exhibit characteristics from more than one level, emphasizing the need for flexible and personalized approaches to support individuals with autism effectively.


Importance of understanding the levels of autism


Understanding the levels of Autism is like having a roadmap to tailor support and interventions uniquely. It’s not just about knowing; it’s about making a real impact in daily lives. It guides educators, caregivers, and professionals in developing effective strategies.

Dive into this guide to discover practical strategies, build connections, and create environments that truly support individuals on the Autism Spectrum.


Decoding Autism: Social Interaction and Repetitive Behaviors


In the past, Autism levels were determined by assessing an individual’s symptoms and challenges across two main domains. In the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the two primary domains are social communication and social interaction and restricted, repetitive behaviors.

  • social communication and interaction

This domain assesses an individual’s ability to engage in social interactions, communicate effectively, and maintain relationships. Difficulties in understanding non-verbal cues, initiating or reciprocating social interactions, sharing emotions, and maintaining friendships are evaluated within this domain.

  •  restricted, repetitive behaviors

This domain assesses the presence of restricted or repetitive behaviors, interests, or activities. It also considers sensory sensitivities or atypical responses to sensory stimuli. These can include repetitive movements (like hand flapping or rocking), Strict adherence to routines, highly focused interests, and unusual responses to sensory input (such as being overly sensitive to certain sounds or textures).

To better understand the two domains, take a look at the symptoms of Autism.


3 Levels of Autism Spectrum Disorder by DSM


In the context of the impact on an individual’s ability to function and communicate, autism spectrum disorder was previously categorized into three levels in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), highlighting the support required.

  • Level 1 –  Requiring Support

Individuals with Level 1 ASD experience difficulties in social communication and interaction, impacting their ability to function and communicate effectively.

Social Communication: They might have challenges in initiating social interactions, maintaining eye contact, and preferring solitary activities. While they can function independently to some extent, they often require support for certain areas. They might have trouble understanding sarcasm or jokes, leading to occasional social misunderstandings.

Restricted or repetitive behaviors: Mild presence of repetitive behaviors, routines or highly focused interests. 

For example, they might have specific routines before bedtime and a strong interest in a particular topic. He might organize objects in a specific way but can adapt if the routine is disrupted.

Sensory Issues: Might have minor sensitivities to certain sensory stimuli or atypical responses.

For example, they may have a minor aversion or preference to certain textures, sounds, or lights. They might exhibit subtle reactions like covering ears in loud environments or avoiding scratchy clothing.

  • Level 2 – Requiring Substantial Support 

Those with level 2 Autism face marked impairments in verbal and non-verbal social communication skills, which significantly impact their ability to function and communicate. 

Social Communication: They might have limited speech or difficulties in understanding or using language.  They have marked impairments in verbal and non-verbal social communication skills.

For example, they might have difficulty understanding personal space and may invade others personal boundaries unintentionally.

Restricted or repetitive behavior: presence of significant repetitive behaviors like hand flapping or pacing, strict adherence to routines, and more pronounced focused interests.

For example, they have intense, focused interests, often talking only about a particular topic without considering others interests.

Sensory Issues: More significant sensitivities to sensory stimuli or pronounce atypical responses.

For example, they become visibly distressed in crowded places due to the noise, cover her ears tightly, and might even cry or have difficulty concentrating. THe sensory overload affects her ability to participate in group activities

  • Level 3 –  Requiring Very Substantial Support

Level 3 Autism indicates severe impairments in social communication, impacting an individual’s ability to function and communicate significantly. They usually need very substantial support in their daily living activities.

Social Communication: People at this level often have minimal speech or communication skills. 

For example, they might struggle to understand emotions or engage in social interactions.

Restricted, Repetitive Behaviors: Severe and pervasive presence of repetitive behaviors like rocking or echolalia, highly strict adherence to routines, and intense focused interests.

For example, their routines are rigid and highly resistant to change, causing significant distress if disrupted.

Sensory Issues: Profound sensitivities to sensory stimuli or extreme atypical responses.

For example, in a supermarket with bright lighting and background noise, someone might have a severe meltdown, dropping to the floor, covering their ears, and becoming overwhelmed, making it challenging to navigate the environment. 

The inclusion of sensory issues is aimed to provide a broader understanding of the challenges individuals with autism might experience. Sensory sensitivities, while not a primary domain for determining the levels of autism, are commonly associated with ASD and can significantly impact an individual’s experiences and behaviors.


Final Words

In conclusion, “Understanding the Levels of Autism” sheds light on the diverse spectrum of this condition and emphasizes its profound impact on individuals. By recognizing and appreciating the varying levels of autism, we pave the way for a more compassionate and inclusive society. 

Individual’s at different levels of the autism spectrum often require different treatments and interventions. Treatment plans are typically tailored to address the specific challenges and strengths associated with each level.
