Level 1 Autism: What Requiring Support Means
Level 1 autism means a person needs support in some parts of everyday life. They may be independent in many areas but still find communication, social situations, change, planning or sensory demands difficult.
This page explains what Level 1 autism means, how it can look in children and adults, how it is diagnosed in Australia, and how it relates to the NDIS.
What Does Level 1 Autism Mean?
Level 1 is one of the three support levels used in the DSM-5-TR autism framework. The three levels are:
- Level 1 – Requiring support
- Level 2 – Requiring substantial support
- Level 3 – Requiring very substantial support
For Level 1, the person has autism-related difficulties that affect daily life and require support.
Clinicians look at two main areas:
- Social communication and interaction
- Repeated behaviours, strong interests, routines and difficulty with change
A person can need different levels of support in these two areas.
Level 1 does not tell you someone’s intelligence, whether they can speak, whether they can work or study, or whether they can live independently. It simply describes the level of support needed in the areas affected by autism.
For the full comparison, see Autism Levels Explained.
Common Signs and Support Needs in Level 1 Autism
Level 1 autism does not look the same for everyone. Some people find social situations hardest. Others struggle more with planning, change, or sensory overload. Common difficulties can include:
- Understanding unspoken social rules
- Starting or keeping conversations going
- Knowing how to respond in social situations
- Coping with unexpected changes
- Moving from one task to another
- Planning and organising everyday activities
- Starting tasks without extra prompting
- Strong need for familiar routines
- Sensitivity to noise, light, touch, smell or busy environments
- Feeling exhausted after long periods of social interaction
A person does not need to have every one of these difficulties to have Level 1 autism.
How Level 1 Autism Can Look in Children and Adults
Level 1 Autism in Children
In children, difficulties often become easier to notice when school and friendships become more demanding. A child may feel comfortable at home where routines are familiar but struggle more with group activities, changing classrooms, unstructured play or making and keeping friendships.
They may also need extra help with organising schoolwork, moving between activities or coping with noisy and busy places. Some children hold everything together during school and then become upset or exhausted when they get home. That can happen because they have spent a lot of energy trying to manage the school environment.
At the same time, they may have strong language, learning skills or deep interests in particular subjects.
Level 1 Autism in Adults
For adults, difficulties can become more noticeable when there is less structure and more responsibility. Work, relationships, appointments, household tasks and managing several responsibilities at once can all become harder.
An adult with Level 1 autism may do well at their job but struggle with sudden changes, workplace social rules, or managing everything outside work. Others find planning, household organisation, sensory overload or social interaction more difficult.
Some adults are diagnosed later in life because they spent years finding their own ways to cope without knowing they were autistic.
Masking Can Make Level 1 Autism Harder to Notice
Some autistic people learn to hide or manage their difficulties so other people do not notice them easily. This is often called masking.
Someone may rehearse conversations before meeting people, copy how others behave, force eye contact, hide sensory discomfort, or stop themselves from stimming in public.
They may look comfortable from the outside while using a lot of energy to get through the situation. For example:
- Someone may complete a full workday but feel completely exhausted afterwards.
- A person may attend an appointment alone but spend hours preparing for it.
- Someone may appear confident in conversation because they have practised what to say beforehand.
Masking is not only seen in Level 1 autism, and it is not used on its own to diagnose autism. But it can explain why a person’s support needs are sometimes missed.
Level 1 Autism vs Level 2 Autism
The main difference is how much support the person needs.
| Area | Level 1 Autism | Level 2 Autism |
|---|---|---|
| DSM description | Requiring support | Requiring substantial support |
| Social communication | Difficulties are noticeable without support | Difficulties remain clear even when support is available |
| Change and routines | Difficulty with change affects some parts of daily life | Difficulty with change has a stronger effect across more situations |
| Overall support | Support is needed | Substantial support is needed |
This does not mean every person with Level 2 autism needs support in exactly the same areas as another Level 2 person. The same applies to Level 1.

How Level 1 Autism Is Diagnosed in Australia
Australia uses recognised autism assessment guidelines to make sure diagnosis looks at the whole person, not just one test or one appointment.bThe Level 1, 2 and 3 terms come from the DSM-5-TR framework.bAn assessment usually looks at:
- Development and history: How the person has communicated, interacted, and managed everyday situations over time.
- Current difficulties and strengths: This includes communication, social interaction, routines, sensory needs and daily functioning.
- Information from different settings: For children, this may include home and school. For adults, it may include work, relationships and everyday life.
Assessment tools may also be used, but no single test decides the diagnosis on its own. The exact professionals involved depend on the person’s age and situation.
Can Someone With Level 1 Autism Access the NDIS?
Yes. Level 1 autism does not mean someone cannot access the NDIS. However, a Level 1 diagnosis by itself does not automatically prove NDIS eligibility.
For Level 1 autism, the NDIS needs evidence showing how autism affects the person’s ability to manage everyday life. The NDIS looks at six main areas:
- Communication
- Social interaction
- Learning
- Mobility
- Self-care
- Self-management
The person needs to show that their permanent disability has a substantial effect in at least one relevant area and that they meet the other NDIS access requirements.
For example, someone may speak clearly but have major difficulty with social interaction or self-management. Another person may manage personal care but need a lot of help organising daily life. That is why NDIS access is based on real everyday impact, not the Level 1 label alone.
What Evidence Helps With a Level 1 NDIS Application?
Good evidence should explain what the person finds difficult in real life. It is more useful to describe actual situations than to only say, “This person has Level 1 autism.”
Strong evidence can show:
- Which activities are difficult to complete alone
- How much prompting or support is needed
- How autism affects work, study or social participation
- Problems with planning and managing daily responsibilities
- How often family or other people need to provide support
- What happens when normal routines change
- How the person functions in different environments
A functional capacity assessment can be useful because it looks closely at daily activities, but it is not required for every NDIS application.
Reports from psychologists, occupational therapists, medical specialists and other relevant professionals can also provide useful evidence.
If masking is part of the person’s experience, the report should explain the practical effect.
For example, saying someone needs hours to prepare for a social activity and then needs a long recovery afterwards is more useful than simply saying they “mask.”
Can Level 1 Autism Change to Level 2?
Autism is lifelong, but the level of support a person needs can change. A child may need different support as school becomes more demanding. An adult may need more help after moving out of home, starting work, or taking on more responsibilities.
Support needs can also reduce in some areas as a person builds new skills or finds an environment that suits them better. If an old autism level no longer reflects the person’s current needs, a qualified clinician can advise whether another assessment is useful.
A change from Level 1 to Level 2 does not change NDIS funding. NDIS plans are based on the person’s individual support needs.
Frequently Asked Questions About Level 1 Autism
Is Level 1 autism mild autism?
Not exactly. The DSM-5-TR calls Level 1 “requiring support.” The term “mild autism” can make the person’s difficulties sound smaller than they really are.
Is Level 1 autism the same as Asperger's syndrome?
No. Asperger’s syndrome used to be a separate diagnosis. DSM-5 brought it and other autism diagnoses under autism spectrum disorder. Some people previously diagnosed with Asperger’s may now fit Level 1, but the terms are not exactly the same.
Can someone with Level 1 autism work or study?
Yes. Many people with Level 1 autism work or study. They may still need support with social interaction, organisation, sensory demands or other parts of daily life.
Can someone have Level 1 in one area and Level 2 in another?
Yes. Autism severity is looked at separately across social communication and repeated behaviours or difficulty with change.
Does Level 1 autism automatically qualify for the NDIS?
No. Level 1 does not give automatic access. The NDIS also looks at how autism affects the person’s daily functioning.
Do I need a functional capacity assessment?
Not always. It can be useful, but the NDIS does not require every applicant to have one.
Does Level 1 autism determine how much NDIS funding someone gets?
No. There is no set NDIS funding amount for Level 1 autism. Funding depends on the person’s individual disability-related needs.
NDIS Autism Support for Individual Needs
A Level 1 diagnosis does not tell a support provider exactly what a person needs. Hilda Care provides NDIS autism support in Melbourne across personal care, life skills, community participation, Supported Independent Living, household tasks, respite and transport. Support is based on the participant’s individual needs and funded services, not only their autism level.
