The National Disability Insurance Scheme (NDIS) Supporting Evidence Form asks clinicians to translate a patient’s history into evidence the National Disability Insurance Agency (NDIA) can use. That involves more than recording a diagnosis. Doctors, specialists and allied health professionals need to describe the resulting impairments, treatment history and everyday function, while staying within their own scope and evidence. A field-by-field approach makes each answer specific, current and clinically supportable.

What is the NDIS Supporting Evidence Form?

The NDIS Supporting Evidence Form is an eight-page document used to support an application to become an NDIS participant. The official form is one accepted way to provide evidence. Recent letters, assessments or reports can be supplied instead if they cover the same information.

The form divides responsibility across three sections:

The current official form is version 1.1, dated 8 April 2020. Applications from 3 October 2024 are decided under the current legislation, and the agency is still updating some online material. Clinicians should therefore use the form to organise evidence, then make sure the whole evidence package addresses the current disability requirements. An attached report may be needed where the form’s small fields cannot capture the necessary detail.

What the evidence needs to establish

The NDIA makes the eligibility decision. A clinician’s role is to provide supported clinical facts and opinions relevant to that decision, rather than declare that a person is eligible.

For the disability requirements, the evidence should address whether:

1. the disability is caused by one or more intellectual, cognitive, neurological, sensory, physical or psychosocial impairments
2. the impairment is, or is likely to be, permanent
3. the permanent impairment substantially reduces functional capacity in at least one of six domains
4. the impairment affects the person’s ability to work, study or take part in social life
5. the person is likely to need NDIS supports for their lifetime.

A diagnosis helps establish the underlying condition. It does not, by itself, show how the resulting impairment meets these requirements. Strong evidence follows a clear chain:

condition and source of diagnosis → impairment → activity limitation → assistance needed → effect on participation

For example, “multiple sclerosis” is a diagnosis. Lower-limb weakness, fatigue and slowed information processing are impairments. The evidence then needs to explain which tasks the person cannot complete reliably or safely, what help they use, how often they need it and how this affects home, work, study or community participation.

Before completing the form

Confirm the request and your role

Read the full form and any request for further information. Confirm whether you are being asked to establish diagnosis and permanency, describe function, address early intervention, or combine these tasks. One professional does not have to provide every part of the evidence.

The treating professional should be appropriate to the person’s primary disability. A doctor or specialist may be best placed to address diagnosis, treatment and permanency, while an occupational therapist, physiotherapist, psychologist or speech pathologist may hold stronger evidence about a particular area of function. Longitudinal knowledge matters: the Access Request Form guidance identifies six months as a helpful treating relationship, rather than a universal threshold.

Assemble the evidence base

Use information you can substantiate, such as:

• specialist letters and diagnostic reports
• hospital and discharge records
• dated treatment history and outcomes
• current examination or observed function
• allied health assessments and progress reports
• standardised assessment results
• information reported by the patient, family or support workers, clearly attributed to its source.

Separate what you observed from what the patient or another person reported. Record the assessment name, date, score and clinical interpretation rather than inserting a score without context. Preferred evidence by disability includes the Expanded Disability Status Scale for multiple sclerosis, the Modified Rankin Scale for stroke and the World Health Organization Disability Assessment Schedule for several cohorts.

Establish authority to disclose

The completed form contains sensitive health information. Confirm the applicant’s authority or other lawful basis for disclosure, explain what information will be sent and record that discussion. Include only information relevant to the NDIS purpose. Our medical support letter guide explains how to distinguish records, reported history, observations and clinical opinion.

How to complete each section

Section 1: applicant details

Compare the person’s full name, date of birth, representative details and NDIS number, if known, with the practice record. Resolve discrepancies before signing. A correct clinical report can still be difficult to match to an application if the identifiers differ.

Section 2: impairment and treatment evidence

Section 2 must be completed by a treating doctor or specialist. Keep the diagnosis and the impairment distinct, then connect them.

Name the primary impairment

The primary impairment is the impairment with the greatest impact on daily life. State the underlying diagnosis and diagnosing source where relevant, followed by the specific loss or change in body function, structure, thinking or learning.

A useful answer identifies:

• the diagnosis and date, or the report that confirms it
• the resulting impairment or impairments
• onset and duration
• why it is the primary impairment
• other significant impairments, without adding unrelated medical history.

Avoid relying on a diagnostic label or writing “see attached” without directing the assessor to the relevant report and finding.

Address whether the impairment is likely to be lifelong

Give a reasoned opinion supported by the condition’s course, treatment response and prognosis. The NDIA considers the permanency of the impairment, which is distinct from whether the diagnosis is permanent. Available and appropriate treatment options are usually considered when deciding whether an impairment is likely to be permanent.

Cover:

• treatments tried, with dates or approximate periods
• adherence or genuine access barriers where relevant
• response, adverse effects and reason for stopping
• current treatment and its purpose
• any remaining known, available, appropriate and evidence-based treatment likely to remedy the impairment
• expected course, including episodic, progressive or fluctuating patterns.

Treatment that manages symptoms or slows progression does not automatically mean an impairment is temporary. Explain the distinction. Do not state that “all treatments are exhausted” unless the evidence supports it, and do not speculate outside your scope.

Complete early intervention questions only with a clinical link

Early intervention is a separate access pathway. If it is relevant, identify the proposed support and explain how it is likely to reduce future support needs, reduce the effect on function, prevent deterioration, improve function or strengthen sustainable informal supports. “The patient would benefit from therapy” is too broad. State the expected functional outcome and the evidence supporting that expectation.

Record assessments precisely

For each assessment, record:

• full assessment name
• completion date
• score, classification or rating
• what the result means for this person’s function
• whether the full report is attached.

Use a measure appropriate to the condition, age and clinical question. A formal score supports the narrative but does not replace it.

Section 3: functional impact across six domains

Section 3 asks whether the impairment creates a need for equipment, assistive technology, home modifications or help from another person. Help can include physical assistance, guidance, supervision or prompting.

For every affected domain, describe:

1. The impairment link: which permanent impairment causes the limitation.
2. The task: what the person cannot start, complete, sustain or repeat.
3. The circumstances: where and when the limitation occurs, including variability.
4. The assistance: who or what helps, how much and how often.
5. The evidence source: observation, assessment, clinical record or attributed report.

These examples show the level of detail, not wording to copy. Use the person’s actual function and evidence. If a domain is unaffected, mark it accurately rather than stretching the evidence across all six.

Describe fluctuating function over time

A single good day can understate an episodic or fluctuating impairment. Describe the pattern over a representative period:

• baseline function
• frequency, duration and triggers of exacerbations where known
• function during an exacerbation
• recovery time
• support needed across the full cycle
• records or observations that establish the pattern.

Use frequencies such as “five mornings each week” or “during two to three episodes a month” where the record supports them. Avoid “often”, “regularly” and “significant” without explaining what they mean.

What to attach

Attach the smallest coherent evidence package that supports the statements in the form. Depending on the person, this may include:

• the diagnostic evaluation or current specialist letter
• a functional capacity or discipline-specific assessment
• standardised test reports with dates and results
• relevant hospital or rehabilitation reports
• treatment summaries that show response and prognosis
• a carer statement, school report or support-worker information that adds day-to-day context.

Confirm that attachments identify the person, author and date. Explain any apparent conflicts, such as an older report describing independent mobility when the current assessment records a decline. Duplicate pages and unrelated records make the key evidence harder to locate.

For psychosocial disability, the Evidence of Psychosocial Disability form collects a treating professional’s evidence about the condition, impairments, treatment and permanency. The evidence package also needs a functional capacity assessment.

Final clinical review before signing

Read the form and attachments as one evidence package. Confirm that:

• the patient identifiers are consistent
• your qualifications, contact details, signature and date are complete
• diagnoses are attributed to their source
• impairments are stated separately from diagnoses
• treatment history includes outcomes and remaining options
• the permanency opinion has a clinical basis
• each functional limitation is linked to an impairment
• assistance type and frequency are specific
• observed, assessed and reported information are distinguished
• fluctuation is described over a representative period
• assessment dates, scores and attached reports agree
• statements stay within your scope and do not decide NDIS eligibility.

Keep the final signed form, its attachments and the disclosure record in the patient record. The applicant or representative can submit evidence through the current NDIS application pathway. The Access Request Form guidance lists the service hub, post and delivery to an NDIS partner or local office for a completed application.

Draft NDIS documents without losing clinical control

Our Documents & Letters workflow can use information from the consult and reviewed clinical note to pre-fill an uploaded PDF or draft a report in a practice template. The output remains a draft: the clinician must review every impairment, treatment, functional statement and evidence source before editing and signing it.
