Why the two-stage audit process exists

The NDIS Quality and Safeguards Commission requires registered providers delivering higher-risk supports — including Supported Independent Living (SIL) — to undergo a two-stage certification audit conducted by an approved quality auditor. The two-stage model exists because documents alone cannot confirm safe practice. Stage 1 establishes whether your organisation has built the right foundations on paper; Stage 2 tests whether those foundations are real in the day-to-day experience of participants and workers.

Under the NDIS Practice Standards (and the strengthened framework progressively taking effect from 2026), SIL providers must demonstrate conformance across the Core Module and the SIL-specific supplementary module. Non-conformances identified at either stage can delay or prevent registration renewal, require corrective action plans, and — in serious cases — trigger Commission compliance action.

Stage 1: the off-site document audit

Stage 1 is conducted remotely. Your approved quality auditor requests a document pack covering the NDIS Practice Standards that apply to your registration groups. They review that pack without visiting your premises, then prepare a preliminary report before Stage 2 begins.

Stage 2: the on-site audit

Stage 2 takes place at your operational sites — including SIL homes where participants live. Auditors are checking that Stage 1 documents translate into real practice. They do this through three primary methods: interviews with participants, interviews with staff and management, and direct observation of the environment and records.

Worked example: SIL provider preparing for a combined audit

The following is a realistic illustration of how a small SIL provider might move through both stages. Names and details are fictional for illustrative purposes.

Audit stage Activity Provider preparation Auditor finding
Stage 1 — document review Incident management policy submitted Policy lists reportable categories and a 24-hour internal escalation timeframe Partial conformance — policy does not specify the NDIS Commission notification window for Priority 1 incidents. Corrective action required before Stage 2.
Stage 1 — document review Worker screening register submitted Register lists all workers with clearance numbers and expiry dates Conformance — register demonstrates current clearances and is actively maintained.
Stage 1 — document review Support plan template submitted Template includes goals section, daily routines, health considerations, and a review date field Conformance — template is sufficiently individualised; auditor will sample completed plans at Stage 2.
Stage 2 — on-site audit Participant interview (three participants across two SIL houses) Provider had conducted pre-audit rights information sessions with participants Conformance — participants could articulate their right to raise concerns and identified the key worker as their first contact.
Stage 2 — on-site audit Staff interview (four support workers) Workers had completed incident reporting refresher training two weeks prior Partial non-conformance — two of four workers could not correctly identify what constitutes a Priority 1 reportable incident. Corrective action plan required.
Stage 2 — on-site audit Record sampling (five support plans reviewed) Plans were updated in the three months before audit Conformance — plans were individualised and referenced each participant's NDIS goals. One plan lacked a documented review date; minor non-conformance noted.

In this example, the provider achieved conditional certification. They were required to submit a corrective action plan addressing the incident reporting knowledge gap and the missing review date within a specified timeframe set by the auditor. The Commission was notified of the outcome through the auditor's certification report.

How to prepare: a practical step list

  1. Map your registration groups to the applicable Practice Standards modules — identify every standard that applies to your services, not just the core module.
  2. Conduct a pre-audit gap analysis — compare each policy against the standard it is meant to meet. Check for missing notification timelines, absent authorisation pathways, and unsigned agreements.
  3. Build a document register — create a master list of every policy, procedure, form, and record the auditor will request, with the version date and owner noted.
  4. Run practice staff interviews — ask your workers the questions auditors ask. Gaps in knowledge become training priorities, not audit findings.
  5. Prepare participants — ensure every participant understands their rights and the complaints process in a way that is accessible to them, and that this is an ongoing conversation, not a one-off form.
  6. Check restrictive practice records — if any regulated restrictive practices are in use, verify each one has current authorisation documentation and has been reported to the Commission.
  7. Address Stage 1 findings before Stage 2 — if your auditor identifies non-conformances at Stage 1, resolve and re-submit before the on-site visit wherever the audit timeline permits.

Providers seeking a head start on document preparation can access the 74-document audit-ready SIL compliance kit at ndiscompliant.com.au, which is structured to the NDIS Practice Standards and designed to address the most common Stage 1 and Stage 2 non-conformances.
