NDIS Supplementary Modules Explained: High Intensity Supports

If you deliver specialised disability supports, NDIS supplementary modules are likely part of your compliance obligations — yet many providers remain unsure which modules apply to them and what each one actually requires. Beyond the Core Module that every registered provider must meet, the NDIS Quality and Safeguards Commission has created six supplementary modules that address higher-risk and more specialised support types. Understanding these modules in full is essential for successful registration, audit readiness, and — most importantly — keeping participants safe. This guide covers every NDIS supplementary module in depth, with particular focus on Module 1: High Intensity Daily Personal Activities, which carries the most stringent worker competency and clinical governance requirements under the entire NDIS Practice Standards framework.

What Are NDIS Supplementary Modules?

NDIS supplementary modules are additional layers of the NDIS Practice Standards that apply to registered providers based on the specific types of supports they deliver. They extend beyond the Core Module to address the distinct risks associated with particular support categories.

The Core Module covers rights and responsibilities, governance, provision of supports, and the support environment — requirements that apply to all registered providers. Supplementary modules build on this foundation for providers delivering services that carry heightened participant risk or require specialist clinical or professional skills. Which modules apply to your organisation depends on your registration groups and the actual supports you deliver, not your organisation’s size or structure.

The Six NDIS Supplementary Modules: An Overview

The NDIS supplementary practice standards currently consist of six distinct modules. Each targets a specific category of support with tailored quality and safety requirements.

1. Module 1 – High Intensity Daily Personal Activities
2. Module 2 – Specialist Behaviour Support
3. Module 2a – Implementing Behaviour Support Plans
4. Module 3 – Early Childhood Supports
5. Module 4 – Specialist Support Coordination
6. Module 5 – Specialist Disability Accommodation

Providers may be subject to one or several of these modules depending on the breadth of their service offerings. It is also possible to be subject to both Module 2 and Module 2a simultaneously — for example, if your organisation both develops and implements behaviour support plans. For a broader look at how these modules fit within the overall registration framework, see our NDIS Practice Standards guide.

Module 1: High Intensity Daily Personal Activities

What Are High Intensity Daily Activities?

High intensity daily activities (HIDA) are supports that carry some of the highest personal risk to participants in the entire NDIS framework. These supports involve complex clinical care tasks that, if performed incorrectly, can cause serious harm or death. Because of this elevated risk, Module 1 — the High Intensity Daily Personal Activities module — imposes some of the strictest requirements of any NDIS supplementary module.

The NDIS Commission defines the following as high intensity daily activities requiring Module 1 compliance:

• Complex bowel care
• Enteral (naso-gastric tube, jejunum or duodenum) feeding and management
• Severe dysphagia management
• Tracheostomy management
• Urinary catheter management (in-dwelling, in-out, and suprapubic)
• Ventilator management
• Subcutaneous injections (including diabetes management)
• Complex wound management
• Epilepsy and seizure management
• Stoma care (integrated into bowel, enteral, tracheostomy, ventilator, and urinary catheter support)

In January 2022, the NDIS Commission released revised High Intensity Support Skills Descriptors (HISSD) that came into effect on 1 February 2022. These updated descriptors brought stronger alignment with the practice standards, elevated wound care to a standalone descriptor, and added dysphagia and diabetes management components. Providers registered for Module 1 must ensure their practices reflect these current descriptors.

Key Requirements Under Module 1

Meeting Module 1 requires your organisation to demonstrate several interconnected systems. Auditors will examine evidence across each of the following areas.

Worker Competency Verification

Workers must demonstrate specific competencies for each high intensity support type they will deliver. Competency verification involves theoretical learning, practical skills demonstration, and formal assessment by a qualified assessor. Workers should only deliver supports for which they hold current, verified competency. Your organisation must maintain tracking systems that flag upcoming competency expiries and ensure workers complete refresher training before delivering supports independently.

Clinical Governance Framework

A clinical governance framework provides the organisational structure ensuring safe, high-quality clinical support delivery. For Module 1 providers, this framework must include clear lines of clinical accountability, defined roles for clinical oversight, supervision arrangements for workers, and mechanisms for escalating clinical concerns. Clinical governance documentation is a primary audit focus for Module 1 assessments.

Participant-Specific Support Plans with Clinical Components

Every participant receiving high intensity supports must have an individual support plan that includes the clinical components relevant to their care. These plans must be current, reviewed regularly, and accessible to all relevant workers. Plans should document the specific support approach, risk management strategies, emergency response procedures, and the qualifications required of workers delivering care.

Emergency Response Procedures

Given the life-threatening potential of errors in high intensity support delivery, providers must have documented emergency response procedures for each support type. Workers must be trained in these procedures and competency-assessed before delivering supports independently. Evidence of emergency procedure training is a key item auditors examine under Module 1.

For further guidance on managing incidents in high-risk support contexts, refer to our NDIS incident management guide and our overview of NDIS reportable incidents.

High Intensity Support Skills Descriptors: What They Cover

The HISSD provide specific guidance for each of the eight primary high intensity support areas. Each descriptor covers three phases of a participant’s care journey:

1. Preparing to deliver supports — skills and knowledge needed before commencing care
2. Implementing the support plan — safe execution of the specific support
3. Reviewing the support — monitoring, documentation, and escalation requirements

These descriptors are supplementary guidance tools rather than mandatory training curricula, but they define the baseline competency expectations that auditors reference when assessing your workforce. Providers who have not reviewed the updated February 2022 descriptors should do so promptly, as the revisions introduced meaningful changes to expected worker competencies across multiple support types.

Module 2: Specialist Behaviour Support

When Module 2 Applies

Module 2 applies to providers whose registered practitioners develop behaviour support plans, particularly those containing restrictive practices. This module focuses specifically on the assessment, planning, and strategy development aspects of specialist behaviour support.

Specialist behaviour support is one of the most tightly regulated support types under the NDIS. The involvement of restrictive practices — physical restraint, chemical restraint, mechanical restraint, seclusion, and environmental restraint — creates significant participant rights and safety considerations that demand robust professional oversight.

Key Requirements Under Module 2

Practitioners delivering specialist behaviour support must meet qualification requirements recognised by the NDIS Commission. The Commission has detailed requirements for both fully qualified practitioners and those working towards qualification under supervision arrangements. Providers must verify practitioner credentials before engagement and establish appropriate supervision for practitioners still developing their qualifications.

Core compliance requirements include:

• Functional behavioural assessments informing all behaviour support plans
• Plans focused on improving participant quality of life, not merely managing behaviour
• Strategies that aim to reduce and ultimately eliminate restrictive practices
• NDIS Commission lodgement compliance for all behaviour support plans containing restrictive practices
• Ongoing plan reviews with documented review evidence
• Communication records with implementing providers and families

Module 2a: Implementing Behaviour Support Plans

Module 2a is a distinct module from Module 2 and applies to providers who implement behaviour support plans developed by others. This commonly applies to support providers whose workers follow plans containing restrictive practices. Module 2a focuses on the fidelity of implementation rather than plan development.

Providers subject to Module 2a must demonstrate:

• Workers have been trained on the specific plans they implement
• Training addresses the functional basis of the participant’s behaviours, proactive and reactive strategies, and authorised restrictive practices
• Monitoring systems track implementation fidelity and behavioural outcomes
• Communication channels with behaviour support practitioners are documented and operational
• Incident documentation demonstrates appropriate responses to behaviours of concern

Providers can be subject to both Module 2 and Module 2a if they both develop and implement behaviour support plans. For information on your broader worker obligations, review our NDIS worker screening guide.

Module 3: Early Childhood Supports

Module 3 applies to providers delivering early childhood early intervention (ECEI) supports to children under 7 years of age and their families. Early childhood supports require a distinct approach that differs fundamentally from supports delivered to adults.

The module reflects the evidence base for early childhood intervention, which emphasises family-centred, inclusive, collaborative, and capacity-building approaches. Providers must demonstrate:

• Family-centred practice approaches that place the family at the centre of all decisions
• Evidence-based intervention methodologies aligned with contemporary early childhood research
• Appropriate qualifications for practitioners delivering early childhood supports
• Collaboration with families, other services, and mainstream early childhood settings
• Culturally responsive practices that recognise family diversity
• Outcome-based approaches that track child and family progress

Module 4: Specialist Support Coordination

Module 4 applies to providers delivering specialist support coordination — an intensive coordination service for participants with complex, multiple, or challenging circumstances. Specialist support coordination differs from standard support coordination in both complexity and the skills required of coordinators.

Key requirements include demonstrated capacity to navigate complex service systems, crisis response and resolution capabilities, capacity building approaches that increase participant independence over time, and active collaboration with mainstream and specialist services. Providers must also demonstrate appropriate conflict of interest management, particularly given the financial relationships involved in support coordination.

For more on support coordination best practices, see our NDIS support coordination best practices resource.

Module 5: Specialist Disability Accommodation

Module 5 applies to providers enrolled to deliver Specialist Disability Accommodation (SDA) under the NDIS. SDA involves the provision of specialist housing designed for participants with extreme functional impairment or very high support needs.

SDA providers must demonstrate that their dwellings meet the enrolled design category requirements, that maintenance and repairs are managed to the required standards, and that tenancy management arrangements respect participant rights and comply with relevant tenancy laws. The intersection of housing and disability support creates complex obligations spanning multiple regulatory frameworks.

For further guidance on SDA, review our dedicated NDIS SDA provider guide.

How Do NDIS Supplementary Practice Standards Relate to Audits?

Supplementary modules are assessed as part of your overall audit against all applicable modules. You do not face separate audits for each supplementary module. Instead, the scope of your certification audit includes every module that applies to your registration groups and service types.

Auditors assess compliance using the NDIS Practice Standards quality indicators, which describe the systems, processes, structures, skills, and behaviours required to achieve each quality outcome. Compliance is evaluated on a four-point scale:

Rating	Level	Meaning
3	Best Practice Conformity	Innovative, responsive service delivery demonstrating continuous improvement
2	Conformity	Clear demonstration that outcomes and indicators are met, proportionate to provider size and scale
1	Minor Non-Conformity	Process evident but lacking supporting documentation or evidence of review; corrective action plan required
0	Major Non-Conformity	Unable to demonstrate appropriate processes or structures; registration precluded until resolved

Three minor non-conformities within the same module may constitute a major non-conformity. Major non-conformities preclude certification, making thorough preparation essential. Consult our NDIS provider registration checklist for a comprehensive overview of registration requirements.

Determining Which Supplementary Modules Apply to Your Organisation

Many providers are uncertain about which supplementary modules apply to them, particularly as they expand their service offerings. Follow this process to determine your applicable modules:

1. Review your current NDIS registration groups and the specific supports you deliver within each group
2. Map each support type against the supplementary module categories listed above
3. Check whether any supports you deliver fall within high intensity daily personal activities, behaviour support, early childhood, specialist support coordination, or SDA categories
4. Review the NDIS Commission’s registration group guidelines for any groups where module application is unclear
5. Contact the NDIS Commission directly if uncertainty remains after your internal review

When you add new registration groups or expand your service offering, repeat this process. Providers who add support types triggering supplementary module obligations must demonstrate compliance with the additional requirements before delivering those supports.

Building an Integrated Compliance System for Multiple Supplementary Modules

Providers subject to multiple supplementary modules face the challenge of building compliance systems that address all requirements efficiently. An integrated approach reduces duplication while maintaining the distinct features of each module.

Begin by mapping shared requirements across your applicable modules. Many supplementary modules share common elements — worker competency frameworks, supervision arrangements, documentation standards, and incident reporting processes. Developing centralised systems that address multiple modules simultaneously reduces administrative burden and improves consistency.

For example, if your organisation delivers both high intensity daily personal activities and implements behaviour support plans, you will need robust clinical governance frameworks for both modules. Rather than maintaining entirely separate systems, build an integrated clinical governance structure with module-specific components nested within a common framework. This approach makes audits more straightforward because evidence of shared systems applies across multiple modules.

Technology solutions can significantly support supplementary module compliance. Learning management systems that track worker competencies and alert you to upcoming expiries are particularly valuable for Module 1 providers. Document management systems with version control support policy currency across all applicable modules. Our overview of NDIS software for providers covers tools that help manage these compliance requirements efficiently.

Worker Training and Competency Across Supplementary Modules

Each supplementary module establishes distinct competency requirements for workers. Understanding these requirements helps providers develop targeted training programs that meet compliance needs without unnecessary duplication.

For Module 1, worker training must be specific to each high intensity support type. Theoretical knowledge alone is insufficient — workers must demonstrate practical competency through supervised practice and formal assessment. Competency records must be current, meaning providers need systems to track when competencies were assessed and when refresher assessment is due.

For Module 2a, training requirements are plan-specific. Workers must be trained on the individual behaviour support plans they will implement, not just generic behaviour support principles. This means your training process must be responsive to individual participant needs rather than relying solely on standing training programs.

Across all supplementary modules, worker qualifications should be verified before engagement and documented in personnel files. Ongoing professional development must be supported and recorded. Supervision arrangements should be proportionate to worker experience and the complexity of supports delivered. For guidance on workforce management, see our NDIS rostering software resource.

Common Compliance Challenges and How to Address Them

Providers delivering supplementary module supports frequently encounter specific compliance challenges. Recognising these common pitfalls helps you address them proactively.

Maintaining worker competency currency under Module 1 is an ongoing challenge as staff turnover and competency expiries create gaps in service capability. Implement tracking systems that provide advance warning of approaching expiries and build succession planning for critical high intensity support competencies. Never allow workers to deliver high intensity supports using expired competency records.

NDIS Commission plan lodgement requirements for behaviour support plans can be difficult to meet consistently under high caseload conditions. Develop efficient, structured plan documentation processes and build quality assurance checks into your workflow. Build in time for review before lodgement rather than relying on final-stage checks.

Consistent implementation of behaviour support plans across shifts and workers is a frequent gap under Module 2a. Clear handover processes, visual guides for complex plans, and regular team meetings to discuss participant progress and implementation questions help maintain implementation fidelity. Auditors will look for evidence that all workers implementing a plan have received plan-specific training.

Communication between Module 2 and Module 2a providers often falls short, leading to implementation gaps. Establish formal communication protocols specifying the frequency and format of communication between behaviour support practitioners and implementing workers. Document these arrangements in service agreements so both parties understand their obligations.

Frequently Asked Questions About NDIS Supplementary Modules

What are the six NDIS supplementary modules?

The six NDIS supplementary modules are: Module 1 (High Intensity Daily Personal Activities), Module 2 (Specialist Behaviour Support), Module 2a (Implementing Behaviour Support Plans), Module 3 (Early Childhood Supports), Module 4 (Specialist Support Coordination), and Module 5 (Specialist Disability Accommodation). Each applies to providers delivering specific types of higher-risk or specialised supports.

Do supplementary modules require a separate audit?

No. Supplementary modules are assessed as part of your overall certification audit, not through separate processes. The scope of your audit covers all modules — Core Module plus any applicable supplementary modules — relevant to your registration groups. This means your audit evidence must address all applicable modules comprehensively.

What triggers the High Intensity Daily Personal Activities module?

Module 1 applies when your workers deliver any of the designated high intensity supports: complex bowel care, enteral feeding, dysphagia management, tracheostomy care, urinary catheter care, ventilator management, subcutaneous injections, complex wound care, or epilepsy and seizure management. The trigger is delivery of these supports, not organisational size or structure.

Can I deliver specialist supports without meeting the relevant supplementary module?

No. If your supports fall within a supplementary module category, you must meet that module’s requirements in addition to the Core Module before delivering those supports. Delivering high-risk supports without meeting the applicable supplementary module requirements may constitute a breach of your registration conditions.

What is the difference between Module 2 and Module 2a?

Module 2 (Specialist Behaviour Support) applies to providers whose practitioners develop behaviour support plans, particularly those containing restrictive practices. Module 2a applies to providers who implement plans developed by others. Organisations that both develop and implement behaviour support plans are typically subject to both Module 2 and Module 2a requirements simultaneously.

What worker qualifications are required under Module 1?

Module 1 does not specify a single mandatory qualification. Instead, workers must demonstrate appropriate competencies for each specific high intensity support type they deliver. The NDIS Commission’s High Intensity Support Skills Descriptors define the skills and knowledge expected for each support type. Workers must be formally assessed as competent before delivering supports independently.

How often do supplementary module competencies need to be renewed?

The NDIS Commission does not prescribe a universal renewal frequency for all competencies. The High Intensity Support Skills Descriptors provide guidance that training should be current, which typically means providers should define refresh intervals based on the nature of each support, worker experience, and any changes to clinical protocols or participant needs. Many providers use annual competency review cycles as a baseline.

What happens if a supplementary module non-conformity is found during audit?

A minor non-conformity requires a corrective action plan to be submitted before certification can be recommended. Three minor non-conformities within the same module may be treated as a major non-conformity. A major non-conformity precludes certification until resolved. Minor non-conformities identified at certification are reviewed at the next surveillance or recertification audit and must be closed within 12 months.
