Frequently asked questions
What is the difference between the NDIS Practice Standards and the NDIS Code of Conduct?
The Code of Conduct sets minimum behaviour expectations for every provider and worker, registered or not — things like acting with integrity, respecting rights, and preventing harm. The NDIS Practice Standards are organisational quality requirements that only registered providers are audited against, covering governance, risk, service delivery and safe environments. You need both: the Code governs conduct, the Standards govern how your organisation is run.
Do I have to meet the NDIS Practice Standards if I'm not registered?
Not currently — unregistered providers follow the Code of Conduct but aren't audited against the Practice Standards. That is changing. Mandatory registration began for SIL and digital-platform providers on 1 July 2026, and from 1 July 2027 it starts extending to personal-care and other high-risk supports, with most providers expected to be registered by around 2030. Confirm the current staging at health.gov.au and ndiscommission.gov.au, as the reforms are Bill-dependent.
Which Practice Standards modules apply to my organisation?
It depends on your registration groups, not your size. Every provider delivering supports meets the Core Module. On top of that you meet any supplementary module matching your supports — for example high-intensity personal activities, specialist behaviour support, early childhood, specialist support coordination, SDA, or the new SIL Supplementary Module from 1 July 2026. Check the Commission's registration groups documents to confirm your exact modules and audit pathway.
How are the NDIS Practice Standards assessed at audit?
An approved quality auditor assesses you against the quality indicators for each applicable Standard, using your documents, your records, and interviews with participants, workers and management. Lower-risk supports go through a lighter verification audit; higher-risk supports (SIL, personal care, SDA, behaviour support) go through a two-stage certification audit including an on-site visit. Evidence must line up across documents, records and interviews — a policy alone is not enough.
How often do I have to be audited against the Practice Standards?
Registration runs in cycles, typically up to three years, with a mid-term audit and a full renewal audit. High-intensity and higher-risk providers may face tighter cycles, and the Commission is tightening audit frequency for some provider types as part of the current reforms. Your certificate states your specific audit dates — treat the next scheduled audit as your working deadline for meeting any new module, such as the SIL Supplementary Module.
