Every child is wonderfully unique. For some children, that uniqueness includes a diagnosis of autism spectrum disorder (ASD). In this guide, we will explore what autism level 1 in children looks like and how families can find the right support, celebrate strengths, and create a roadmap for joyful growth.
Let’s start off by explaining what level 1 autism looks like in children.
Autism Level 1 Defined: What Is Level 1 Autism?
Under the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders), autism level 1 is considered the least support-intensive classification of autism. It falls under the umbrella of ASD, or autism spectrum disorders, which encompasses the wide range of symptoms that can be seen in those diagnosed with autism.. Autism level 1 is often denoted as “requiring support” in professional settings, and is the first of three levels of autism.
Children with level 1 autism typically have strong potential for independence but benefit from structured support in areas like social communication and flexible thinking.
So, what do common symptoms look like in children?
What Does Autism Level 1 Look Like?
Each child is uniquely their own person and may show certain behaviors differently. Each level of autism is broad and diagnosis is ultimately left to the professional’s interpretation. However, as a generalization, children with level 1 autism may:
- Prefer routines and find change overwhelming
- Have some noticeable deficits communicating or expressing interest
- Exhibit highly-focused interests or repetitive behaviors
- Show interferences with back-and-forth conversation
- Express sensitivity to sensory input (like sounds, textures, or lights)

Furthermore, it is important to note that a child with Level 1 autism may not have significant language delays but you could see irregularities in language use.
For example, they may speak in very formal tones or focus intensely on specific topics. It is their way of connecting with the world around them, and through hands-on, compassionate support, communication and social skills can be expanded to help them make more meaningful connections with others around them.
How Is Autism Level 1 Diagnosed?
Diagnosis follows the same process for all levels of autism and is an important step in driving positive outcomes for children and families. Level 1 autism is typically diagnosed by a developmental pediatrician, psychologist, or licensed professional through a combination of:
- Behavioral observations
- Parent interviews and developmental history
- Standardized tools such as the ADOS-2 (Autism Diagnostic Observation Schedule) or the ADI-R (Autism Diagnostic Interview-Revised)
Furthermore, the process of diagnosing level 1 autism involves:
- A thorough evaluation by healthcare professionals using standardized criteria from the DSM-5
- The child exhibiting persistent interfering behaviors with social communication
- The presence of at least two interfering behaviors
Diagnosis typically involves a combination of parental input and direct observation by medical professionals. Parents provide valuable insights into their child’s developmental history and behavior patterns, while professionals conduct assessments to observe the child’s interactions and responses. This comprehensive approach ensures that the diagnosis is accurate and tailored to the child’s specific needs.
Since autism level 1 symptoms can be subtle, particularly in early childhood, some children may not be diagnosed until they begin school, when social interactions and adaptability are more strongly emphasized.
According to the CDC’s ADDM Network, 1 in 31 (3.2%) children aged 8 years have been identified with ASD, and early diagnosis can significantly improve developmental outcomes through timely support.
How Does Autism Level 1 Impact Everyday Life
Since every kid is unique and flourishes in their own way, it is important to know that daily life can look very different from child to child. In general, those with level 1 autism may excel in structured settings but feel overwhelmed in unpredictable environments like school cafeterias or birthday parties. This can create strong feelings within the child if they feel confined or overfaced in a specific setting.
Sometimes, they might deeply enjoy solo activities, such as reading or collecting. Meanwhile, transitions to new activities can be tough, and sudden changes may lead to emotional responses.
However, with the right support and strategies, children with level 1 autism can build meaningful relationships and enjoy group activities.

By observing activities your child likes to engage in, and where and how they participate, a parent and their support network (like ASD specialists and ABA therapists) can promote positive interactions and utilize specialized techniques for interfering behaviors.
Support doesn’t mean limitations; it means helping your child unlock their potential in a way that honors who they are from the inside out.
Best Support Options for Autism Level 1
One of the most effective, research-backed treatments for children with level 1 autism is Applied Behavior Analysis (ABA) therapy. This child-led, naturalistic approach makes learning fun through 1:1 sessions that are designed to maximize positive learning outcomes.
Through designated centers that specialize in ABA therapy, such as Bierman Autism Centers, the therapy is delivered in a play-based, engaging environment that’s built around each child’s interests and strengths.
ABA therapy can help children with level 1 autism learn:
- Communication and language skills
- Social skills like sharing, turn-taking, and empathy
- Emotional regulation and executive functioning skills
- Daily living skills like dressing or brushing teeth
Other supportive therapies for level 1 autism may include:
- Speech therapy (for social communication)
- Occupational therapy (for sensory processing or motor coordination)
For those who want to encourage their children to learn and grow in a safe, compassionate, and supportive environment, it is important to note that these therapies are not about changing who a child is. Rather, they are about empowering them to express themselves, make connections, and explore the world with confidence.
How Parents Can Support a Child with Autism Level 1
As a parent, you play an essential role in your child’s journey through life. In fact, you are your child’s #1 champion, co-adventurer, and cheerleader.
Here’s how you can support your child’s growth:
- Create consistent routines to provide predictability
- Use visual supports like schedules or picture cards
- Encourage play that aligns with your child’s interests
- Celebrate small victories, whether it’s trying a new food or initiating a hello
Play is powerful. Whether it’s building a LEGO spaceship or hosting a teddy bear tea party, playful moments can build skills, confidence, and connection.
And remember, you are not alone. You have an entire network of groups, centers, and other parents of children with level 1 autism that are just around the corner to help you along your way.
