Autism is the single largest diagnostic group in the NDIS. More than 270,000 autistic participants — approximately 35 per cent of the entire scheme — rely on NDIS supports to live, learn, work, and participate in their communities.

The I-CAN v6 assessment is designed to measure functional support needs, not diagnoses. This is a meaningful shift for autistic participants — because the functional impact of autism on daily life is often invisible, frequently misunderstood, and highly variable in ways that a single 90-minute assessment session can easily miss.

This guide explains what matters, what is different about autism in the I-CAN v6 context, and how to prepare a preparation document that accurately reflects genuine needs.

Why Autism Requires Specific Preparation

The I-CAN v6 assessment measures what a participant can and cannot do across 12 life domains. For many disability types, the functional impact is relatively consistent and visible — someone who uses a wheelchair, for example, presents a similar functional picture on most days and in most environments.

Autism does not work this way.

Autistic people often present differently in different environments. They may perform well in a structured, calm, one-on-one setting (like an assessment room) while struggling significantly in the demands of daily life — sensory environments, unexpected changes, social navigation, executive function demands, and the accumulating fatigue of functioning in a predominantly neurotypical world.

The result is a risk that an I-CAN v6 assessment, without careful preparation, captures an autistic person's best-case performance rather than their typical daily functioning.

Good preparation closes that gap.

Masking: The Most Under-Documented Autistic Experience

Masking — also called camouflaging — is the effortful process of suppressing autistic behaviours and mimicking neurotypical social norms in order to avoid negative consequences.

Most autistic people mask to some degree. Many mask extensively, particularly those diagnosed later in life, those with ASD Level 1 diagnoses, and autistic women and girls who have learned through years of social feedback that their authentic presentation is unwelcome.

Masking matters enormously for an I-CAN v6 assessment because:

• An autistic person who is masking in an assessment room will appear significantly less impaired than they actually are in daily life
• The assessor is observing a performance, not genuine functioning
• The cost of masking — exhaustion, sensory overwhelm, emotional dysregulation, and post-assessment shutdown — is completely invisible during the session itself

If you or your family member masks, this must be described explicitly in your preparation documentation.

What to document:

• That masking occurs, and in what situations
• What masking costs — typical recovery time, post-masking exhaustion, shutdown or meltdown patterns
• What functioning looks like when masking is not possible or breaks down
• How frequently masking is unsustainable

Domain-by-Domain: How Autism Presents in I-CAN v6

Self Care

Executive function difficulties — starting tasks, sequencing steps, transitioning between activities — frequently affect personal hygiene and daily self-care routines for autistic people in ways that are not related to physical capacity.

What to document: How long self-care tasks take, what prompting is required to initiate them, whether sensory sensitivities affect hygiene (certain textures, temperatures, or products), and what happens when routines are disrupted.

Example: "Showering requires verbal prompting on most days. Without prompting, it may not happen. Sensory sensitivities to water temperature and certain soap products mean we have worked through multiple products to find one that is tolerable. Getting dressed can take 45 minutes if the 'preferred' clothes are unavailable."

General Tasks and Demands

Autism significantly affects the ability to manage daily routines, medication, and personal safety — particularly due to executive function difficulties, demand avoidance, and rigidity around routine.

What to document: Whether the person can follow a consistent daily routine independently or requires prompting and external structure; what happens when routines are disrupted (distress, shutdown, or complete breakdown of functioning); ability to manage medications reliably; any safety concerns or vulnerability to exploitation.

Example: "Requires a detailed visual schedule to navigate the day. Any unplanned change to routine — even minor ones like a different support worker arriving — can trigger hours of distress and make the rest of the day unmanageable. Cannot be relied upon to take medication without daily reminders due to time-blindness and working memory difficulties."

Domestic Life

Executive function difficulties — initiating tasks, sequencing steps, tolerating sensory aspects of domestic environments — frequently create significant barriers to managing a household for autistic people.

What to document: Whether the person can shop for groceries independently (supermarkets are often highly challenging sensory environments); ability to plan and safely prepare meals (sequencing, fire safety, decision fatigue); ability to manage cleaning and laundry (initiation difficulties, sensory aversions to cleaning products); whether domestic tasks require prompting, support, or cannot be done independently.

Example: "Cannot manage supermarket shopping independently due to sensory overwhelm in busy environments. Cooking requires step-by-step verbal prompting for each stage to avoid skipping steps or leaving the stove unattended. Cleaning typically does not happen without external prompting due to executive function difficulties in initiating non-preferred tasks."

Communication

Communication differences are central to autism for many people — though they present very differently across the autistic spectrum.

What to document:

• Verbal vs non-verbal communication preferences
• Difficulties with expressive communication under stress or fatigue
• Literal interpretation of language causing misunderstandings in important situations
• Use of AAC (Augmentative and Alternative Communication) devices or strategies
• The difference between communication in a familiar, calm setting and communication under demands

Important: Many autistic people who communicate fluently in everyday conversation struggle significantly in high-stakes, novel, or complex communication situations — medical appointments, NDIA interactions, conflict situations. Document this gap if it exists.

Mobility

Physical mobility is usually intact in autism. However, document any relevant motor coordination difficulties, proprioception challenges, or sensory sensitivities affecting travel and community access.

Interpersonal Interactions & Relationships

This domain is often significantly affected for autistic participants.

What to document: Difficulties understanding unspoken social rules; the effort required to maintain social relationships; patterns of social fatigue or withdrawal; challenges with authority relationships; any history of exploitation or being taken advantage of due to social naivety.

Example: "Social interaction is effortful and exhausting. After social situations — including professional appointments — recovery typically takes several hours. Friendships require significant deliberate effort to maintain. There have been several situations where social naivety led to being taken advantage of financially."

Learning & Applying Knowledge

What to document: For children, the adjustments and supports required at school. For adults, any education history affected by undiagnosed or unaccommodated autism, and current learning barriers.

Life Long Learning

Many autistic people have genuine vocational goals or skills they want to develop — but significant barriers prevent them from pursuing or sustaining these.

What to document: Employment or vocational goals and what barriers autism creates to pursuing them; whether workplace sensory environments, social complexity, or the cost of masking make sustained employment difficult or impossible; history of job loss related to autistic traits; what support would enable the person to pursue career or skills development goals.

Example: "Has a strong interest in IT and has completed two short courses, but has been unable to maintain any employed role beyond 3–4 months. The social demands of workplace communication and the sensory environment of open-plan offices have ended each employment attempt. Would benefit from supported employment with a job coach and a sensory-appropriate work environment."

Mental & Emotional Health

Autistic people have significantly higher rates of co-occurring mental health conditions — anxiety, depression, PTSD — than the general population. These are often direct consequences of living in a world not designed for autistic people.

What to document: Co-occurring mental health conditions and how they interact with autism in daily life; the impact of chronic masking on emotional wellbeing; autistic burnout (distinct from depression — a period of significantly reduced functional capacity following prolonged masking); whether mental health support is currently in place and whether it is accessible for autistic people.

Example: "Experiences severe anxiety that is autism-specific in nature — triggered by unpredictability, sensory overload, and social demands rather than generalised worry. Sees a psychologist fortnightly but finding an autism-informed provider took over a year. During burnout periods — which occur approximately twice yearly and last 4–6 weeks — is unable to maintain any of the daily functioning that is otherwise managed with support."

Community, Social & Civic Life

What to document: Actual community participation levels (not aspirational); sensory barriers to community access; the post-participation cost that prevents sustained participation.

Domestic Life

Executive function difficulties — initiating tasks, sequencing steps, tolerating sensory aspects of domestic environments — frequently create significant barriers to managing a household for autistic people. See the General Tasks and Demands section above for how routine management affects the broader domestic environment.

What to document: Ability to shop for groceries (sensory challenges in supermarkets, executive function for shopping lists, financial management while shopping); ability to plan and safely prepare meals; ability to manage cleaning and laundry reliably; whether domestic tasks require prompting or cannot be done independently.

Behaviours of Concern

What to document: Any behaviours of concern — including self-injurious behaviour, aggression, property destruction, or elopement — in the context of their triggers and frequency. If a Behaviour Support Plan is in place, describe it.

Important note: "Challenging behaviour" in autism is almost always a communication of unmet need or overwhelm. Document the behaviour, the context, and the function — this framing helps the assessor understand what support is needed.

Physical Health

Autistic people have higher rates of co-occurring physical health conditions than the general population. Physical health conditions are often overlooked in autism assessments because the focus tends to be on cognitive and social-communication needs.

What to document: Any physical health conditions that affect daily functioning — epilepsy (more common in autism), gastrointestinal conditions (constipation, IBS, reflux are significantly more prevalent), sleep disorders (difficulty falling and staying asleep, irregular sleep-wake patterns), chronic pain, or other physical conditions requiring ongoing management. Describe how each condition affects daily life and what health management support is needed.

Preparing for the Assessment Itself

Request accommodations in advance

Before the assessment, contact the NDIA or your Support Coordinator to request:

• An assessor with autism experience
• Extended assessment time, or assessment across multiple shorter sessions
• A familiar environment (your home, if preferred)
• Use of AAC or written communication if verbal communication is difficult under pressure
• Permission to bring a support person

These accommodations are appropriate and should be requested proactively.

Bring a preparation document

A written preparation document covering all 12 domains gives the assessor information that a conversation alone cannot reliably capture — particularly for masking participants, those with alexithymia (difficulty identifying one's own emotional states), or anyone who finds it difficult to self-advocate under the pressure of an assessment setting.

Prepare the participant for what to expect

For many autistic people, unfamiliar situations are themselves a significant source of distress. Describe the assessment in advance — who will be there, what questions will be asked, how long it will take, and what happens next. A social story or visual schedule may help, particularly for children and young people.

Describe good days AND difficult days

If functioning is variable — good periods and difficult periods — document both. How many days per week is a "good day"? What triggers difficult periods? How long do they last?

A Note on Late-Diagnosed Adults

Many autistic adults — particularly women, non-binary people, and those with ASD Level 1 — were not diagnosed until adulthood. They may have spent decades masking extensively, and may have developed significant co-occurring mental health conditions as a result.

For late-diagnosed adults, the preparation challenge is often twofold: describing the current functional impact of autism, and explaining the cumulative cost of years of unaccommodated autistic experience.

Both are legitimate and important. Both belong in a preparation document.
