Autism Level 2 (Substantial Support Needs): Symptoms, Diagnosis, and Treatment Options

At Thriving Wellness Center, we recognize that autism exists on a spectrum — and with that comes a wide variety of support needs. In this post, we focus on Autism Level 2, sometimes described as “requiring substantial support.”

Finding clarity and balance—many adults with Autism Level 2 move through life seeking understanding, emotional stability, and support. At Thriving Wellness Center, we help individuals navigate their neurodivergent strengths and challenges with compassionate, specialized care.

Autism Level 1, sometimes referred to as High-Functioning Autism or historically as Asperger’s Syndrome, describes individuals who are independent in most areas of daily living but still experience meaningful challenges in social communication, emotional regulation, executive functioning, and sensory processing. Many people with Level 1 autism spend years masking or feeling misunderstood before realizing that their experiences fit the autistic profile.

At Thriving Wellness Center, we specialize exclusively in identifying and supporting Autism Level 1 in teens and adults through comprehensive diagnostic evaluations and neurodiversity-affirming therapy. Our practice is specifically designed for individuals with Level 1 profiles — those who are verbal, independent, and seeking deeper self-understanding, improved coping strategies, and meaningful support for daily challenges. We do not provide services for Level 2 or Level 3 autism, allowing us to focus our expertise on the unique needs and experiences of the Level 1 community.

What is Autism Level 2?

The DSM-5 (the standard diagnostic manual) defines Level 2 as:

• Significant challenges in social communication (both verbal and nonverbal), with impairments that remain obvious even with supports in place.

• More pronounced restricted and repetitive behaviors, such as strong resistance to change, inflexible routines, or repetitive movements/interests, which occur frequently and interfere with daily functioning in multiple contexts.

In other words: compared to Level 1, Level 2 reflects a greater degree of support need — but not the “very substantial support” seen in Level 3.

Reclaim Energy and Self-Acceptance

If you’ve been feeling drained from trying to ‘fit in,’ you’re not alone. Our neurodiversity-affirming therapists in New Jersey and New York specialize in helping autistic adults recover from burnout and reconnect with their authentic selves.

Common Characteristics of Autism Level 2

People with Level 2 autism can present in many ways — no two profiles look the same. But there are some patterns that tend to emerge more often for Level 2:

1. Social Communication Differences

Individuals may experience:

• Speech may be limited or tend to come in short, simple sentences rather than long, complex ones.

• Trouble initiating or sustaining conversations, or difficulty responding appropriately to social cues (e.g., limited eye contact, missing nonverbal signals, or walking away during conversations).

• Social interactions might be limited to narrow “special interests” rather than broader peer relationships.

2. Behavioral & Routine-Related Traits

• Strong need for routines and significant distress or disruption when routines are changed or interrupted — more so than what you might see at Level 1.

• Frequent restricted or repetitive behaviors or interests (e.g., repetitive movements, intense focus on specific topics).

• Difficulty coping with change — transitions or unexpected events can lead to significant distress.

3. Impact on Daily Life

• Many people with Level 2 will need consistent support at school, work, or home — more than occasional check-ins or “coaching.”

• Challenges in independent self-care, executive functioning, or regulation may be more noticeable than in Level 1. For more support on these challenges, explore our ADHD Therapy and Executive Function Coaching.

Why the “Level of Support” Matters

Assigning a support level is not about “how smart” someone is, or labeling someone as “high-” or “low-functioning.” Rather, it’s a practical tool to clarify what kind of support, accommodations, or interventions are likely to be helpful — and needed consistently.

Support & Treatment Options for Level 2

At Thriving Wellness Center and beyond, many of the same interventions used for Level 1 can be adapted or expanded to meet the needs of individuals with Level 2 — often with more structure, consistency, and support.

Here are common supports and approaches for Level 2 autism:

• Comprehensive Diagnostic Assessments — to clarify the individual’s strengths, challenges, and support needs (e.g., language, adaptive functioning, sensory processing).

• Structured Therapy

  • Neurodiversity-affirming psychotherapy to support emotional regulation, social skills, and self-advocacy.

  • Occupational therapy / sensory integration for sensory sensitivities, sensory regulation, and daily living skills.

  • Behavioral supports or interventions, especially around rigid routines, emotional regulation, and flexibility.

• Skills Coaching & Supports

  • Social-skills groups or social support groups — in small, structured, predictable settings.

  • Executive functioning supports — routines, external structure, task-management tools, adaptive strategies.

  • Accommodations at school, work, or home — predictable schedules, clear expectations, sensory accommodations, communication supports.

• Family & Caregiver Support — support and guidance for caregivers, family members, or support staff to understand autism, respond appropriately, and help build consistency.

• Community & Peer Support — connection with others on the spectrum (in similar support levels), neurodiversity-affirming spaces, and supportive community resources.

For many, a diagnosis provides a sense of clarity—and a path forward. For more on signs of autism in adults, visit our related post: 10 Key Signs of Autism in Adults

Final Thoughts: Understanding Is the First Step

A Level 2 autism diagnosis doesn’t define how “capable” someone is. Rather, it highlights that the person may benefit from substantial, consistent support in communication, flexibility, sensory regulation, and daily functioning.

With a supportive, neurodiversity-affirming approach, people with Level 2 can build meaningful lives — drawing on strengths, building self-advocacy, and accessing the right supports to flourish.

If you’re curious about whether Level 2 fits your experience, or want to explore diagnosis or support options — we’re here to walk that path with you.
