For many NDIS participants, the occupational therapy assessment is the most important step on the road to Specialist Disability Accommodation. It’s the point where your daily life, your abilities, and your housing needs are put into a report that carries real weight. If you’re planning to look at SDA Vacancies in Perth, understanding how that assessment works, and how to prepare for it, can make a big difference to the outcome.
One clarification first: the title says the assessment “decides” your design category, and that’s a useful shorthand, but it’s not quite precise. The occupational therapist (OT) gathers evidence and makes recommendations. The NDIA makes the final decision about whether SDA funding is approved and which design category and building type apply. A strong OT report is the main thing that shapes that decision, which is why preparation matters so much.
What Is an SDA-Related OT Assessment?
Specialist Disability Accommodation is NDIS funding for specially designed housing for participants with extreme functional impairment or very high support needs. SDA funds the home and its design features, not the support workers inside it. Those supports are funded separately, often through Supported Independent Living (SIL) or other parts of your plan.
To access SDA, the NDIA needs evidence that you meet the eligibility criteria and that specialised housing is reasonable and necessary for you. An OT assessment provides much of that evidence. The OT looks at how your disability affects your everyday life and what features your home would need to support you safely and independently.
The assessment is typically funded from your plan, often under capacity building support, so check with your support coordinator about how it’s arranged.
What the OT Is Looking At
A thorough assessment covers more than a diagnosis. Two people with the same condition can have very different needs, so the OT focuses on function, how you actually manage day to day. Areas commonly explored include:
Mobility and transfers. How do you move around your home? Do you use a wheelchair, walking aid, or other equipment? How do you get in and out of bed, the shower, or a chair, and do you need hoists or other assistance?
Personal care. What help do you need with showering, toileting, dressing, and eating? How much support is required, and how many people are involved?
Cognition and communication. How do you process information, make decisions, and communicate? Do you need prompting, structure, or visual cues to move through your home?
Sensory needs. Are there sensory sensitivities, such as noise, light, or crowded spaces, that affect your wellbeing?
Behaviour and safety. Are there behaviours of concern that put you or others at risk, or that have caused damage to a home? How have past living arrangements worked out?
Assistive technology and equipment. What equipment do you use now, and what might you need in the future? Does your home need to accommodate particular devices?
Current housing. How well does your present home meet your needs? What barriers or risks does it present?
Your goals and preferences. What do you want from your living situation? Where do you want to live, with whom, and what matters most to you?
How the Findings Connect to Design Categories
The OT’s observations help point towards the design category that best matches your needs. In broad terms:
Improved Liveability relates to needs where sensory, intellectual, or cognitive impairments call for a home designed to support understanding, orientation, and independence.
Fully Accessible relates to significant physical impairment requiring a high level of physical access, such as step-free entry and accessible bathrooms and kitchens.
Robust relates to complex needs, including behaviours of concern, where a physically resilient home reduces risk of injury and damage and supports a stable tenancy.
High Physical Support relates to significant physical impairment with very high support needs, often involving assistive technology, reinforced structures for equipment such as hoists, and backup power.
The OT explains how your functional needs line up with these descriptions, and what evidence supports that conclusion. The NDIA weighs the report alongside other information when making its decision.
How to Prepare for Your Assessment
Preparation helps the OT see an accurate picture of your life. Here’s how to get ready.
1. Gather your existing documents
Collect reports and records that show your needs. These may include:
- Your current NDIS plan
- Medical and specialist reports
- Previous OT, physiotherapy, or allied health assessments
- Hospital or discharge summaries where relevant
- Records of equipment you use
- Information about past housing arrangements, including any that didn’t work out
The more complete the picture, the stronger the evidence.
2. Think through a typical day, and a hard day
Write down your routine from waking to sleeping. Note where you need help, what is difficult, and what takes extra time or effort. Then think about your worst days, not just your best. Assessments sometimes happen on a good day, and it’s easy to underplay difficulties without meaning to. Be honest and specific.
3. Involve the people who know you
Family members, carers, and support workers often see things you might not think to mention. If possible, invite them to be part of the assessment, or ask them to write down what they observe. Their input can add important details about safety, behaviour, and support needs.
4. Make a list of problems with your current home
Note the barriers you face now: a bathroom you can’t use safely, doors too narrow for your equipment, stairs, noise, or anything else that affects your daily life. Specific examples are far more useful than general statements.
5. Be clear about your housing goals
Tell the OT what matters to you. Do you want to live alone or with others? Which areas do you prefer, and why? What would make a home feel like yours? The assessment should reflect your voice, not just your clinical needs.
6. Write down your questions
Ask the OT how the report will be used, what it will include, and what happens next. You’re entitled to understand the process.
What Happens on the Day
Assessments vary, but you can generally expect:
- A conversation about your history, routines, and goals
- Observation of how you move, transfer, and manage tasks
- A look at your current home, either in person or through detailed discussion
- Questions about your supports and how they work in practice
- Possibly some standardised assessment tools
Don’t try to perform or minimise. The aim is for the OT to see how you truly function. If you tire easily, need breaks, or rely on someone for help, show and say so.
After the Assessment
The OT will prepare a report, which supports your SDA application and, if approved, helps guide the search for a suitable home. It’s reasonable to ask for a copy, read it carefully, and raise anything that doesn’t seem accurate or complete. Your support coordinator can help you understand how the report fits into the wider application.
Once the NDIA has made its decision, your plan will show whether SDA is approved, along with your design category and building type. If the outcome isn’t what you expected, ask about your options, including review rights. Your support coordinator or an advocate can guide you through that process.
Common Mistakes to Avoid
Treating the assessment like a test. There’s nothing to pass. The goal is accuracy.
Downplaying difficulties. Many people are used to coping and don’t realise how much they manage. Be honest about what’s hard.
Going in without documents. Previous reports and records strengthen the evidence.
Leaving out carers and supports. They hold valuable information.
Forgetting future needs. If your condition is likely to change, tell the OT. Housing needs to work over the long term.
Not asking questions. Understanding the process helps you take part in it confidently.
Searching While You Wait
While your assessment and application are in progress, you can still get ready. Learn about the design categories, speak to providers, and join waitlists. Knowing what’s out there helps you act quickly once your plan is approved. Remember that you can contact several providers and compare them, which gives you real choice when the time comes.

Final Thoughts
The OT assessment is the foundation of your SDA journey. It captures how your disability affects daily life and translates that into a clear case for the housing you need. The OT recommends and the NDIA decides, but a thorough, honest, well-supported assessment gives you the best chance of an outcome that fits.
Gather your documents, think through your days, involve the people who know you, and speak up about what matters.
