The NDIS Practice Standards Core Module defines 412 individual Quality Indicators across 32 Outcomes across 4 divisions. In theory, an Approved Quality Auditor checks all 412. In practice, audit time is finite (1-3 days on site), and auditors triage. The Quality Indicators they consume the most audit-time on — and that SIL providers fail most often — are roughly the same twelve every time. Triaging your prep around these gives the highest return on hours invested.
What Quality Indicators actually are
Each NDIS Practice Standards Outcome is broken into Quality Indicators — specific statements describing what an auditor expects to see in operation. For example, Outcome 2.4 (Incident Management) has Quality Indicators including: "The provider has a documented incident management system," "Incidents are recorded and analysed to identify trends," "Reportable incidents are notified to the NDIS Commission within required timeframes." Each Indicator is what an auditor checks evidence against. NDIS audit evidence is structured around the QI list, not the Outcome list.
Why these twelve carry the most weight
Three reasons certain Quality Indicators get more audit-time:
- SIL-specific scrutiny. SIL providers face additional scrutiny on Outcome 4 (Provision of Supports Environment) and Outcome 3.2 (Support Delivery) because they operate group residences with overnight support. The on-site walk-through tests physical-environment Indicators specifically.
- Historical failure rate. The NDIS Commission's published audit data and ANAO reports indicate certain Outcomes have higher non-conformance rates than others. Auditors front-load time on these because they expect to find findings.
- Cross-system Indicators. Indicators that test multiple parts of your system (e.g. risk management → incident management → continuous improvement) get more attention because they reveal whether your operation is integrated or siloed.
The 12 highest-leverage Quality Indicators
| QI Area (Outcome) | What auditors check | Kit document |
|---|---|---|
| Incident Management — system completeness (2.4) | Policy + report form + register + reportable-incident process. Auditor expects all four — missing register is most common failure. | Doc 01 + Doc 26 + Doc 41 + Doc 62 |
| Reportable Incidents — Commission notification (2.4) | Evidence that 24-hour and 5-day notification timeframes are understood by staff and met when applicable. Staff interview-tested. | Doc 62 (Reportable Incident Quick Reference) |
| Risk Management — live register (2.2) | Risk register with SIL-specific risks (not just generic), reviewed in last quarter, with ratings, treatments, and review dates. | Doc 03 + Doc 47 |
| Internal Audit — program AND execution (2.3) | Internal audit schedule + at least one completed internal audit report + remediation evidence for any findings. | Doc 09 + Doc 51 + Doc 52 + Doc 43 |
| Worker Screening — currency & supervision (2.6) | Every staff member's NDIS Worker Screening Check is current. Where any clearance was pending, supervision plan covered the gap period. | Doc 04 + Doc 44 |
| Code of Conduct — training evidence (2.6) | Signed acknowledgement on file for every staff member. Training register shows when each was trained on the Code. | Doc 31 + Doc 46 |
| Support Delivery — daily evidence (3.2) | Progress notes for every participant showing goal-linked support delivery. Notes interview-tested with staff. Notes Rewriter is the staff-training tool here. | Doc 15 + Doc 35 + Doc 36 |
| Safe Environment — physical inspection (4.1) | SIL House Safety Inspection completed regularly (monthly). Fire safety plan displayed. PPE/first-aid accessible. Walked through by auditor on site. | Doc 18 + Doc 38 + Doc 53 |
| Medication Management — MAR completeness (4.3) | Medication Administration Record (MAR) for every participant who receives medication support. Storage secure. Errors tracked. | Doc 19 + Doc 39 |
| Restrictive Practices — register + authorisation (4.3) | Every restrictive practice documented with authorisation, reporting evidence, and review dates. Empty register is acceptable if no restrictive practices apply. | Doc 50 |
| Complaints & Feedback — closure trail (1.5) | Complaints register with complaints logged, investigated, resolved, and linked to improvement actions. Empty register is a yellow flag for under-reporting. | Doc 02 + Doc 60 + Doc 42 |
| Continuous Improvement — live register (2.3) | Continuous Improvement Register with ongoing entries driven by feedback, incidents, complaints, internal audits. Demonstrates the operation learns from its operations. | Doc 09 + Doc 43 |
If you can confidently demonstrate each of these twelve with all three legs of the evidence tripod (see below), you've covered roughly 60% of audit-day time. The remaining 40% goes to the other 400 Indicators, where auditors sample rather than exhaustively check.
The evidence tripod: policy + record + practice
For every Quality Indicator, an auditor checks three legs:
- Policy — does a document describe how this Indicator is met?
- Implementation record — is there a register, log, or file showing the policy in action over time?
- Observable practice — does the manager describe operation consistent with the policy? Do staff describe operation consistent with the policy and manager? Does the physical environment match the documented setup?
If only one leg is there, the tripod falls. This is why the policy-practice gap is the highest-failure pattern across every Outcome — providers have leg 1 (policies) but legs 2 and 3 are missing or inconsistent.
Every Quality Indicator covered, mapped, documented
The 74-document Complete SIL Kit was built around the QI list. Each document references its Practice Standards QIs. $297 early bird (GST-inclusive AUD).

Three test methods, applied in combination:
- Document review. Open the policy, the register, the form. Check the document control box, the version, the Practice Standard reference. Look for currency (recent review date).
- Sampling. Pick 2-3 participant files, 2-3 staff files, 2-3 register entries, 1-2 SIL houses. Check that documents promised by the policy actually exist for those samples. Sample isn't predictable — you can't choose; you can only make sure every file would survive sampling.
- Interview & observation. Talk to the manager, talk to 2-3 staff (one-on-one, not together). Walk the SIL house. Ask "what would you do if [scenario]?" Compare the answers against what the policy says. This is where the policy-practice gap is found.

Mapping every QI to a kit document
The master mapping document — the one we use ourselves — is Doc 63 (Audit Evidence Checklist) in the kit. Every one of the 412 Quality Indicators is listed with the evidence types an auditor expects to see, mapped to which of the 65 kit documents satisfies that Indicator. You walk into audit with this checklist printed and annotated; the auditor walks in with their own list. Matching them in advance is half the audit.
For the higher-level mapping of every kit document to its Practice Standards Outcome, our SIL Audit Survival Guide is the cornerstone article that walks through the four Core Module divisions and the 32 Outcomes. For the broader audit-prep timeline, see the NDIS quality audit preparation 6-month roadmap.
If you're starting prep from scratch with the 1 July 2026 deadline in sight, the Complete SIL Kit ($297 early bird, GST-inclusive AUD) is the documentation foundation this article's prioritisation is built around. Every Quality Indicator covered, every document Practice-Standards-mapped, every register pre-structured. The 30-day guarantee means there's no risk in checking the QI mapping against your situation.
