If your child has been diagnosed with autism spectrum disorder (ASD), you’ve likely heard terms like “Level 1,” “Level 2,” or even “high-” or “moderate-support” autism. These levels come from the DSM-5 and describe how much support a person needs in daily life — not their intelligence, worth, or potential.
Understanding these levels helps families identify which therapies, school supports, and strategies may help most. But remember: autism is a spectrum, not a ladder. Many children move between levels as they grow, depending on environment and support.
What the Levels of Autism Mean
The DSM-5 classifies autism into three levels based on the amount of daily support needed:
| Autism Level | Description | Support Needed |
|---|---|---|
| Level 1 | “Requiring support” | Mild social and behavioral challenges |
| Level 2 | “Requiring substantial support” | More noticeable communication and flexibility difficulties |
| Level 3 | “Requiring very substantial support” | Significant communication and adaptive challenges |

Level 2 Autism: “Requiring Substantial Support”

- Emotional dysregulation or meltdowns when routines are disrupted.
Example in Daily Life

- Communicates best through visual aids (PECS, speech device, gestures).
- Needs consistent adult support during transitions.
Strengths and Supports
- Structured teaching approaches (ABA, TEACCH) to simplify tasks.
- Speech and occupational therapy for communication and sensory needs.
- Predictable visual schedules for routine consistency.
- Positive reinforcement systems to motivate engagement.

- Build Communication Alternatives: Encourage gestures, pictures, or devices to support speech.
- Celebrate Small Wins: Each step forward—tying shoes, trying a new food—matters.
- Collaborate with Teachers: Share progress and strategies between home and school.

Jayden, Age 6 (Level 2): Jayden uses a speech device and loves building with blocks. His parents created a color-coded picture routine for mornings. Over time, Jayden learned to press “All done” on his device to transition smoothly—and meltdowns nearly disappeared.
