This article is general information only and does not constitute legal, compliance, or regulatory advice. NDIS High Intensity Support Skills Descriptors requirements should be verified against the current published guidance from the NDIS Quality and Safeguards Commission, and providers should seek their own compliance advice before making decisions based on this content.
The High Intensity Support Skills Descriptors set out the skills and knowledge a worker needs to safely deliver high-risk personal care — things like complex bowel care, enteral feeding, tracheostomy support and wound management. They’re published by the NDIS Quality and Safeguards Commission, and they apply to providers registered to deliver High Intensity Daily Personal Activities under Module 1 of the NDIS Practice Standards.
Here’s the gap most providers don’t see until an audit finds it. You can usually produce a certificate showing a worker attended training on bowel care or wound care. What you often can’t produce is evidence that the worker is currently competent to perform it, on this participant, under this support plan.
That’s not a paperwork problem. It’s a structural one. Training completion and competency are different things, and the descriptors are built entirely around the second one. If your training program only tracks the first, you’re carrying risk you can’t see.
This guide breaks down what the descriptors actually require, who they apply to, and what a defensible evidence trail looks like — without assuming you’ve spent years inside NDIS quality frameworks.
TL;DR – NDIS High Intensity Support Skills Descriptors Explained
The High Intensity Support Skills Descriptors (HISSD) are published by the NDIS Quality and Safeguards Commission and set out the skills and knowledge a worker needs to safely deliver high-risk personal supports under Module 1 of the NDIS Practice Standards — including complex bowel care, enteral feeding, tracheostomy support, ventilator support, urinary catheter care, subcutaneous injections, and complex wound care. The current version took effect 1 February 2023. The descriptors are structured around demonstrated competency rather than training attendance: each covers preparing to deliver a support, delivering it per the participant’s plan, and reviewing it, with an expectation that assessment stays current rather than being certified once and left unreviewed.
For providers, the practical gap is that a completed training record isn’t the same as competency evidence — auditors assessing Module 1 registration look for a documented trail per worker and per task: who assessed competency, when, what triggers reassessment, and what happens if a worker doesn’t pass. Tribal Habits, an Australian LMS, addresses this through platform features including Observation (checklist-based, assessor-graded task verification) and Requirements (credential and licence tracking with expiry-based recertification triggers), both available on all plans. Organisations needing workforce-wide reporting on competency gaps by role can also use the Roles, Competencies and Skills framework, available on Business 50+ plans.
What are the High Intensity Support Skills Descriptors?
The skills descriptors are supplementary guidance from the NDIS Commission. They describe the skills and knowledge a support worker needs to safely prepare for, deliver, and review a high intensity support — and auditors use them to assess whether a provider is meeting Module 1 of the NDIS Practice Standards.
They apply to providers registered for registration group 104 — High Intensity Daily Personal Activities. If your organisation isn’t registered to deliver these supports, the descriptors don’t apply to you directly. If you are, they’re the document an auditor will hold your training and assessment records against.
The current version came into effect on 1 February 2023, replacing an earlier set of descriptors. The Commission has revised the applicable dates and scope before, so if you’re building a compliance case around a specific requirement, check the current published document rather than relying on a summary — including this one.
Eight support categories are formally linked to Module 1:
| High intensity support | What it typically covers |
|---|---|
| Complex bowel care | Non-routine bowel management, including PRN laxatives, enemas or suppositories |
| Enteral feeding and management | Nasogastric, gastrostomy (PEG) or jejunostomy feeding, and medication delivered via feeding tube |
| Dysphagia support | Supporting participants with swallowing difficulties, including modified diets and mealtime risk |
| Tracheostomy support | Care and management of a tracheostomy, including airway clearance |
| Ventilator support | Supporting a participant who relies on mechanical ventilation |
| Urinary catheter care | Management of indwelling or intermittent catheters |
| Subcutaneous injections | Administering medication via subcutaneous injection |
| Complex wound care | Managing wounds that require more than routine first aid |
A ninth area — epilepsy and seizure support — has its own skills descriptor but sits separately as an additional support that may co-occur with the core eight, rather than a formally linked Module 1 category. Worth knowing, because it’s often listed alongside the other eight in informal summaries.
What’s at stake if the evidence trail doesn’t hold up
Module 1 registration isn’t a formality — it’s generally understood to be what allows a provider to deliver these supports to NDIA-managed participants. An audit finding that your competency evidence doesn’t match what the descriptors expect isn’t just a corrective action item. Depending on the severity and pattern of the gap, it’s the kind of finding that can put a provider’s registration status for that support category at risk — though the specific consequences of any audit finding depend on your circumstances and are a matter for the Commission and your own compliance advice, not something this article can determine for you.
The risk isn’t limited to the audit outcome, either. These are the highest-risk supports in the NDIS Practice Standards for a reason — a worker who was signed off as “trained” but wasn’t actually competent to deliver a specific task is a safety incident waiting to happen, not just a compliance gap.
What the descriptors actually require — beyond “completing training”
Competency versus completion — the distinction auditors check for
A completion record tells you someone finished a course. It doesn’t tell you they can perform the task correctly, under supervision, on a real participant, today. The descriptors are written around the second standard.
This shows up directly in how the document is structured. Each descriptor is broken into three stages: preparing to deliver the support, delivering it in line with the participant’s plan, and reviewing how it went. That’s a competency framework, not a course outline — and it’s generally expected to be assessed as one, with a worker observed and signed off, not simply tested on knowledge.
Ongoing currency — why a one-off certificate isn’t enough
High intensity supports change. A participant’s care plan is reviewed. A wound heals differently than expected. A feeding regimen is adjusted by a clinician. The descriptors reflect this by expecting training and practice to stay current — not a single certification that sits unchanged for years.
In practice, that generally means:
- Reassessment when a participant’s support needs change materially
- Periodic competency review, not just initial sign-off
- A documented trigger for retraining if a worker hasn’t performed the task recently
Who can deliver the training
The descriptors don’t prescribe a single approved trainer. Guidance suggests training and oversight should come from “an appropriately qualified health practitioner” where relevant, and should reflect the nature of the support and the worker’s experience — but it stops short of requiring a nurse or allied health professional for every scenario. What matters more, per the Commission’s own framing, is that the training is documented and the competency review is real.
What good competency evidence generally looks like
A training calendar on its own doesn’t demonstrate competency. What auditors generally expect to see is an evidence trail showing a specific worker was assessed as competent to perform a specific high intensity task, and that the assessment has stayed current.
In practice, many providers find it useful to keep the following on hand, per worker and per task:
- A record of the initial competency assessment — not just attendance
- The name or role of the person who carried out the assessment
- The assessment date, and any expiry or review trigger
- What happens if competency lapses or a retake is needed
Providers should confirm current audit expectations directly with their NDIS auditor or the Commission’s published guidance, as this list reflects common practice rather than a fixed checklist.
How Tribal Habits helps you evidence high intensity competency
Most training platforms are built to record that someone finished something. Evidencing competency against a framework like this needs more than a quiz score and a completion date — it needs a structured way to observe a task, grade it against your own criteria, and keep that record current.
Here’s what that looks like in a platform, and how Tribal Habits approaches each piece:
Checklist-based competency assessment. The Observation element lets you build an item-by-item checklist for a specific high intensity task — a subcutaneous injection procedure, a wound dressing change, a tracheostomy care routine — with pass/fail or scored grading and formal assessor sign-off per item. That’s a structurally different record from a quiz result: it shows what was actually observed, by whom, and against what standard.
Ongoing currency, not one-off attainment. The Requirements element captures licences, certifications or credential evidence with expiry dates, and can trigger automated recertification reminders as those dates approach. That directly supports the “ongoing currency” expectation in the descriptors — competency that’s tracked against a renewal cycle, not treated as permanent from day one.
Workforce-wide visibility, not just individual records. On Business 50+ plans, the Roles, Competencies and Skills framework lets you map exactly which staff are required to hold which high intensity skills, and report on attainment gaps across your whole team — so you can see who’s covered, who’s expiring soon, and who has a gap, before an auditor finds it for you.
This is a platform capability, not a ready-made high intensity training course — you bring the clinical content and assessment criteria; Tribal Habits gives you the structure to build, assign, assess and track it.

Frequently Asked Questions
Do the High Intensity Support Skills Descriptors apply to unregistered NDIS providers?
Generally, registration for Module 1 (registration group 104) is understood to relate to accessing NDIA-managed participants rather than being a blanket requirement to deliver these supports at all — an unregistered provider may be able to deliver them to self-managed or plan-managed participants. Registration is what brings an independent audit against the Practice Standards, which is where the skills descriptors are directly applied. Registration requirements can be specific to your circumstances, so confirm your obligations directly with the NDIS Commission or your own compliance advisor rather than relying on this summary.
How often does high intensity competency need to be reassessed?
The descriptors don’t set a fixed interval — guidance suggests reassessment should reflect the worker’s experience, the nature of the support, and any change to the participant’s plan. Many providers build a defined review cycle (commonly annual, or triggered by a plan change) to keep this defensible and consistent.
What’s the difference between the skills descriptors and general compliance training?
General compliance training typically confirms someone completed a course. The skills descriptors are built around demonstrated, assessed competency — observed performance of a specific task, signed off by an assessor, and kept current. One is a record of attendance; the other is a record of capability.
Do I need a nurse to deliver high intensity training?
Not necessarily. Guidance points to training being delivered or overseen by “an appropriately qualified health practitioner” where relevant, but the descriptors stop short of mandating a nurse or allied health professional in every case. This is a judgement call specific to your service — worth confirming with your own clinical governance advisor rather than treating as settled.
Where can I find the official descriptors document?
The NDIS Quality and Safeguards Commission publishes the current skills descriptors directly on its website (view them here). Because dates and scope have been revised before, it’s worth checking the live document rather than a third-party summary when you need a specific compliance date.
Disclaimer: The regulatory details referenced in this article — including registration group numbers, effective dates, category scope, and audit expectations — are provided for general guidance only. Always confirm current requirements directly with the NDIS Quality and Safeguards Commission’s published descriptors, and obtain advice from a qualified NDIS compliance professional before relying on this information for audit or registration purposes.
The record you can defend is the one that matters
Most providers aren’t short on training. They’re short on proof that training turned into competency, and that competency has stayed current. The High Intensity Support Skills Descriptors make that distinction explicit — and audits are starting to test for it directly.
Building that evidence trail doesn’t need a bigger training team. It needs a structure that separates “attended” from “assessed,” and “assessed once” from “currently competent.” Get that structure right, and the audit conversation changes from defending gaps to showing your workings.
