You do not have to buy an FCA to apply for the NDIS. The NDIA states that an FCA can help describe the effect of an impairment, but other relevant evidence may be sufficient.
Before booking a private assessment, find out what information is missing and whether the documents you already have can answer the question.
Eligibility involves more than one report
An applicant needs to meet the age and residence requirements and the relevant disability or early-intervention requirements. New applicants must be younger than 65 when they apply in the required way.
For the disability requirements, evidence about an impairment, whether it is likely to be permanent and its effects on activities and participation is important. A diagnosis alone does not establish every requirement, and a description of difficult activities alone may not establish permanence or treatment history.
The NDIA's eligibility guidance explains the full requirements and the available pathways. An assessor should not imply that a particular questionnaire score or preferred wording guarantees access.
What evidence might already help?
Relevant information can come from treating professionals and other appropriate contributors. It may include letters, reports, existing assessments and descriptions of activities and assistance.
A professional report does not have to be an FCA to contain useful functional evidence. Equally, a diagnosis letter may leave some practical questions unanswered. Look at the information itself rather than the document title.
An NDIS partner or contact can help explain the application process and what supporting evidence is needed.
When an FCA may add useful information
An FCA may help when the effect on daily activities has not been adequately described, when several sources need to be considered together or when a specific functional question remains.
The report should identify its methods and evidence sources, explain activities and support, and state any limitations. It should draw appropriately on treating evidence rather than make unsupported conclusions about diagnosis or permanence.
Tell the provider what other evidence exists and what the NDIA has asked for before agreeing to the scope.
Check costs and alternatives
A privately purchased assessment before access is not automatically reimbursed if the application succeeds. Ask what existing evidence can be used and whether a public, community or government access-assistance service is available for your circumstances.
Availability varies. Some targeted services help eligible people obtain assessments, so it is inaccurate to say that everybody must always pay privately. It is equally inaccurate to promise that free assessment is available to everyone.
Keep current requirements separate from future changes
NDIS access reforms have been announced for January 2028. They should not be described as the process already applying to every applicant in September 2026.
Check current official advice when preparing an application, particularly if it is close to an age limit or another deadline. Commissioning an FCA does not itself lodge an application or preserve a deadline.
