Do you need an NDIS Worker Screening Check?

Whether you need an NDIS Worker Screening Check depends on the role you do and the kind of provider you work for. The check is not a blanket requirement for everyone in the disability sector. For some roles it is legally mandatory, for others it is a choice the provider or participant makes. This guide explains the distinction, the narrow exception for students, and how mandatory registration for SIL and platform providers, in force since 1 July 2026, has pulled more roles into the mandatory category.

If you only want the application steps and per-jurisdiction detail, see the state-by-state breakdown.

What the check actually is

An NDIS Worker Screening Check is a national assessment of whether a person poses a risk to people with disability. It is conducted by your state or territory worker screening unit and recorded against the national NDIS Worker Screening Database. The outcome is either a clearance or an exclusion.

The check considers national police history alongside other sources, including findings of workplace misconduct and relevant disciplinary or tribunal records. Because police history is bundled into the check, a separate National Police Check (Nationally Coordinated Criminal History Check) is not required for the same risk-assessed role.

A clearance is valid for five years and is portable: it stays with the worker across different roles and providers while it remains current. When it nears the five-year mark, see how to renew an NDIS Worker Screening Check.

When the check is mandatory

The check is mandatory when a worker holds a risk-assessed role with a registered NDIS provider.

A risk-assessed role is broadly any position that involves more than incidental contact with people with disability, or direct delivery of specified supports and services. This captures most frontline support work, and the requirement applies regardless of employment type:

• Employees
• Contractors and subcontractors
• Volunteers
• Students on placement (subject to the exception below)

If a person performs a risk-assessed role for a registered provider, they must hold a current clearance. There is no informal substitute. AHPRA registration, a qualification, or a previous police check does not replace an NDIS Worker Screening Clearance for these roles.

When the check is a choice

The picture is different outside registered providers.

• Unregistered providers are not legally required to make their workers hold a clearance. They may choose to, and the NDIS Commission recommends that they do.
• Self-managed and plan-managed participants can decide whether the workers who support them must hold a clearance. They can ask an unregistered provider or an individual worker to obtain one as a condition of engagement.

So a worker supporting a self-managed participant through an unregistered provider may not be legally required to hold a clearance today. That does not mean it is wise to go without one. A clearance is portable and signals to future engagers that the worker has been screened, which makes it a practical asset even where it is optional.

The work-experience exception

There is one narrow exception worth knowing. Secondary school students completing formal work experience in a risk-assessed role may do so without their own clearance, provided they are directly supervised at all times by a worker who holds a current NDIS Worker Screening Clearance.

This is a limited carve-out for structured school placements. It is not a general pathway for new workers to start before screening, and the supervision requirement is strict. Anyone relying on it should confirm the current conditions with their state worker screening unit and the provider.

What changed on 1 July 2026

The line between mandatory and optional moved on 1 July 2026. From that date, providers of Supported Independent Living (SIL) and NDIS digital platform providers must be registered with the NDIS Commission, and registration is what triggers mandatory worker screening. Providers already operating had until 1 October 2026 to apply; a provider that missed that deadline has to stop delivering those supports. Two classes of support were added to the Provider Registration Rules to make this work: 0137 (providing an NDIS digital platform service) and 0138 (assistance with supported independent living). The detail is on the NDIS Commission's mandatory registration page.

The practical effect is that many workers who previously operated under unregistered arrangements, where screening was optional, now work for a registered provider and need a clearance in a risk-assessed role. Registered SIL and platform providers carry the same obligations as every registered provider: audits, incident management and worker screening across the risk-assessed workforce.

The Commission has signalled that more higher-risk supports could follow as the reform program continues. Treat anything beyond SIL and platforms as direction rather than law until the Commission confirms it. SIL providers should also read the SIL compliance overview.

The provider risk of "recommended but not required"

For providers, the most common trap is treating screening as optional simply because the law currently allows it for a given arrangement. Two risks follow.

• The arrangement can change. A provider moving from unregistered to registered, or a support type moving into mandatory registration, can flip an optional check into a legal requirement overnight. Workforces built without screening then need urgent remediation.
• Optional is not the same as safe. The NDIS Commission recommends screening even where it is not mandated. Engaging unscreened workers in roles with vulnerable people carries real safety and reputational exposure regardless of the registration status.

A defensible position is to screen every risk-assessed role to the mandatory standard, then keep evidence that each clearance is current. That way a change in registration status does not create a compliance scramble.

How Koora fits

Koora checks the credentials that sit behind a risk-assessed role, including the NDIS Worker Screening Clearance, so a worker arrives with a Career Passport rather than a folder of loose documents. The Passport travels with the worker across roles and providers, which suits the portable nature of the clearance.

Koora tracks the clearance to its expiry date and flags it before it becomes a gap, so a five-year clearance does not quietly lapse. Monitoring of the clearance itself runs upstream: the worker screening unit keeps checking and notifies you as a linked provider if a decision changes. This reduces the manual chasing. The provider keeps the legal responsibility for who they engage, and for confirming a worker holds the clearances their role requires. Koora shows the position as at the moment a report runs, not a reconstructed history. Where you already use other systems, Koora integrates via API and webhooks today, and can build a direct integration on request.

Frequently asked questions

Does an NDIS Worker Screening Check include a police check?

Yes. The NDIS Worker Screening Check assesses national police history as part of the clearance, so you do not need a separate National Police Check for the same role. The check also draws on other records such as workplace misconduct and relevant tribunal findings, then issues a single clearance or exclusion outcome.

How long is an NDIS Worker Screening Clearance valid?

A clearance lasts five years from the date it is issued, then must be renewed. There is no grace period if it lapses. If your clearance expires while you are still in a risk-assessed role, you must stop performing that role until a new clearance is granted. Apply well before the expiry date.

Can a worker start before their clearance is granted?

Only in limited cases set by the NDIS Commission, and the provider keeps the legal duty to decide. A common pathway is supervised work while an application is pending, with the provider managing risk. Always confirm the current rules with the NDIS Commission before letting anyone begin a risk-assessed role.
