NDIA Interview Questions: Real Examples for 2026
How NDIA Interviews Work in 2026
The National Disability Insurance Agency recruits under the Australian Public Service merit-based selection framework. That means every interview is structured, every answer is scored against a pre-set rubric, and every candidate on the shortlist is being measured against the same capability standard.
A few features of NDIA interviews that distinguish them from interviews at other agencies:
- Questions provided 24 hours in advance. Most NDIA interview processes at APS5 and above — and many at APS4 — provide the full question set to candidates the day before the interview. This raises the bar: panels expect structured, evidence-based answers, not improvisation. Candidates who treat the 24-hour window as a scripting exercise rather than a preparation window consistently underperform.
- Dual-framework assessment. NDIA panels assess candidates against both the APS Integrated Leadership System (ILS) capability clusters and the NDIA’s own values — accountability, collaboration, innovation, and dedication to excellence. Questions are designed to surface evidence across both dimensions simultaneously.
- NDIS knowledge is a live requirement. The NDIA administers the National Disability Insurance Scheme. Panels expect candidates at every level to demonstrate working knowledge of the NDIS Act, the NDIS Code of Conduct, the role of the NDIS Quality and Safeguards Commission, and the current reform and transition agenda — not just generic public service knowledge.
- Panel typically includes two to three members. Standard NDIA panels include a chair (usually the hiring manager or their delegate), a technical or subject matter member, and often an independent equity representative. Questions are typically divided across panel members and scored individually before scores are combined.

Behavioural Interview Questions (ILS Capability-Mapped)
Behavioural questions form the core of every NDIA interview at every classification level. They are framed as “Tell me about a time when…” and require a specific, real example drawn from your professional experience. The STAR method — Situation, Task, Action, Result — is the expected response structure, and at PS Interview Coach we extend this to STAR-L, adding a Learning component that panels consistently respond to.
The following questions are mapped to the ILS capability clusters most commonly assessed at NDIA.
Achieves Results
- “Tell me about a time you managed a high-volume or complex caseload and still delivered quality outcomes. How did you prioritise?”
- “Describe a situation where you had to meet a tight deadline with limited resources. What did you do, and what was the outcome?”
- “Give me an example of a time you identified a problem in a process and took steps to fix it. What was the impact?”
Communicates with Influence
- “Tell me about a time you had to deliver a difficult or unwelcome message to a participant, provider, or stakeholder. How did you approach it?”
- “Describe a situation where you needed to adapt your communication style significantly for your audience. What did you change, and why?”
- “Give an example of a time you successfully brought people to a shared position when there were competing views.”
Cultivates Productive Working Relationships
- “Tell me about a time you collaborated with people across different teams or organisations to achieve a shared outcome.”
- “Describe a situation where a working relationship was difficult. How did you manage it?”
- “Give me an example of a time you supported a colleague or team member who was struggling. What did you do?”
Exemplifies Personal Drive and Integrity
- “Tell me about a time you faced an ethical dilemma at work. How did you handle it, and what guided your decision?”
- “Describe a situation where you maintained your position under pressure when you believed you were right. What happened?”
- “Give me an example of a time you received critical feedback. How did you respond?”
Thinks Strategically (APS6 and above)
- “Tell me about a time you had to take a longer-term view when the short-term pressures were pushing in a different direction.”
- “Describe a situation where you identified an emerging risk or opportunity before it was on your team’s radar. What did you do with that insight?”
NDIS Framework and Knowledge Questions
NDIA interview panels probe NDIS knowledge in two ways: direct knowledge questions, and knowledge embedded within scenario or behavioural questions. Candidates who cannot distinguish between the NDIA (the agency) and the NDIS (the scheme it administers), or who cannot accurately describe the role of the NDIS Quality and Safeguards Commission, are significantly disadvantaged from the first response.
The following are real question types that appear in NDIA recruitment processes.
Direct Knowledge Questions
- “What is your understanding of the objects of the NDIS Act, and how do they shape the NDIA’s day-to-day decisions?”
- “How does the NDIS Code of Conduct differ from the APS Code of Conduct, and why does that distinction matter in this role?”
- “What is the role of the NDIS Quality and Safeguards Commission, and how does it relate to the NDIA’s functions?”
- “How would you explain the concept of reasonable and necessary supports to a participant with limited prior NDIS experience?”
- “What do you understand about the current NDIS reform agenda, and how do you think it will affect the work of this team?”
Knowledge Applied in Behavioural Context
- “Tell me about a time you had to apply a legislative or policy framework to a complex or ambiguous situation. How did you navigate it?”
- “Describe a situation where you needed to explain a complex policy decision to someone who did not agree with the outcome. How did you handle it?”
- “Tell me about a time you identified that a participant’s needs had changed significantly. What steps did you take, and what frameworks guided your response?”
For each of these question types, the panel is assessing whether your knowledge is current, applied, and framed in the right terms. Knowing the NDIS Code of Conduct’s seven obligations, understanding the structure of NDIS plans and review mechanisms, and being able to speak to the current support for life transition are baseline expectations — not advanced preparation. Our NDIA interview preparation guide includes a full NDIS framework briefing mapped to the most common knowledge probe areas.
NDIA Values Alignment Questions
The NDIA’s four organisational values — accountability, collaboration, innovation, and dedication to excellence — are assessed both directly and through the framing of behavioural questions. Panels are listening for whether these values appear naturally in the way you describe your work, or whether they are bolted on as afterthoughts at the end of an answer.
Participant Choice and Control
- “Tell me about a time you supported a participant to make a decision you personally disagreed with. How did you balance your duty of care with the participant’s right to choose?”
- “Describe a situation where you had to empower someone to exercise their rights when it would have been easier to make the decision for them.”
Accountability and Integrity
- “Tell me about a time you identified an error — your own or someone else’s — and took steps to address it. What did you do?”
- “Describe a situation where you were asked to do something that felt inconsistent with your professional values. How did you respond?”
- “Give me an example of a time you had to make a decision without being able to consult your manager. What guided you?”
Safeguarding and Mandatory Reporting
- “Tell me about a time you identified a safeguarding concern involving a vulnerable person. What did you do, and what was the outcome?”
- “What steps would you take if a participant disclosed to you that they were experiencing abuse or neglect from a provider?”
- “Describe how you have maintained a person’s dignity and confidentiality in a situation involving sensitive disclosures.”
The safeguarding question in particular is non-negotiable preparation for any NDIA interview. Expected elements include: immediate prioritisation of the participant’s safety, reference to mandatory reporting obligations under the NDIS Quality and Safeguards Commission framework, documentation, and appropriate escalation — all while maintaining the participant’s dignity. A vague answer will not score.
Scenario and Hypothetical Questions
Scenario questions test your judgement in NDIA-relevant situations where there is no single right answer — only more and less defensible reasoning. They are framed as “What would you do if…” or “How would you handle a situation where…” and are designed to assess whether your decision-making process is sound, not just your conclusions.
Many candidates prepare thoroughly for behavioural questions but treat scenarios as improvisation. This is a critical error. Scenario questions require a clear thinking framework applied consistently under panel observation.
- “A participant contacts you upset that their NDIS plan has been approved with less funding than they requested. They believe the decision is unfair and want you to change it immediately. How do you handle this?”
- “You are reviewing a participant’s plan and notice that their current supports do not appear to be meeting their stated goals. The registered provider has signed off on everything. What do you do?”
- “A participant’s support coordinator contacts you to say the participant wants to change providers urgently due to concerns about the current provider’s conduct. What steps do you take?”
- “You discover a potential conflict of interest between a colleague and a provider organisation during a compliance review. Your colleague is unaware you have noticed. How do you handle it?”
- “You are managing a caseload of 90 participants and two plan reviews are due on the same day. One involves a participant in a crisis situation; the other involves a participant whose review is already overdue by two weeks. How do you prioritise and what do you do?”
For scenario questions, structure your answer around: what your immediate actions would be, why you would take those actions (referencing the relevant framework or principle), who you would involve, and what outcome you would be working toward. Panels are scoring your reasoning process, not just your conclusion.
EL1 and EL2 Leadership Questions
Executive Level interviews at the NDIA assess an expanded capability set that includes team leadership, strategic contribution, stakeholder management, and the ability to drive outcomes at an organisational — not just individual — level. The questions below appear at EL1 and EL2, and the expected depth of response increases substantially at EL2.
EL1 — Team Leadership and Operational Management
- “Tell me about a time you led a team through a period of significant change or uncertainty. How did you maintain performance and morale?”
- “Describe a situation where a team member was underperforming. How did you address it, and what was the outcome?”
- “Give me an example of a time you had to make a decision with incomplete information and under time pressure. What did you do?”
- “Tell me about a time you identified a gap in your team’s capability and took steps to address it.”
EL2 — Strategic Leadership and Organisational Impact
- “Tell me about a time you drove a significant change initiative. How did you build the case, manage stakeholder resistance, and deliver the outcome?”
- “Describe your approach to building and maintaining high-performing teams in a complex, high-pressure environment.”
- “Give me an example of a time you influenced policy or strategic direction beyond your direct area of responsibility.”
- “Tell me about a time you had to balance organisational risk against participant or stakeholder needs. How did you navigate it?”
- “Describe a situation where you had to make an unpopular decision as a leader. How did you communicate it and manage the aftermath?”
At EL2, panels are assessing whether you operate with the mindset and capability of an executive, not an accomplished individual contributor. Your examples must demonstrate influence, strategic thinking, and accountability at a level that goes beyond task execution — regardless of how strong the underlying story is. Preparing EL2 responses requires a fundamentally different approach to example selection and framing than APS-level preparation. This is one of the most specialised elements of the coaching we provide at PS Interview Coach — if you are targeting an EL2 role, that preparation starts with our NDIA interview preparation guide and continues through live mock panel sessions.
Questions to Ask the NDIA Panel
The questions you ask at the end of an NDIA interview are assessed as part of your overall performance. They signal your level of sector knowledge, your genuine interest in the role, and whether you are thinking at the right level for the classification. Generic questions about team culture or flexible working arrangements do not make a positive impression at interview — ask those of HR after you receive the offer.
The following are examples of questions that demonstrate genuine insight at the NDIA level:
- “How is this team or branch contributing to the current NDIS reform and transition program, and how does this role sit within that work?”
- “What does success look like in this role at the six-month mark, from the hiring manager’s perspective?”
- “How does the team currently balance participant-facing work with the internal compliance and reporting requirements of the role?”
- “What are the biggest capability development opportunities within this team for someone coming in at this level?”
- “How is the NDIA approaching workforce capability building in response to the changing demands on participant planners and engagement staff?”
One question per panel is typically appropriate. Choose the one that is most genuinely relevant to what you want to know — panels can tell the difference between a prepared question and a scripted one.
How to Prepare for NDIA Interview Questions
Knowing the questions is the starting point, not the destination. The gap between a candidate who has read a list of NDIA interview questions and one who performs at panel level is the work that happens between reading and the interview room.
Effective NDIA interview preparation involves four steps:
- Build your example bank. Map your professional experience to the ILS capability clusters relevant to your target classification. For each cluster, identify two or three specific, real examples that demonstrate your individual contribution, judgement, and impact. Do not rely on one example across multiple questions.
- Structure every example using STAR-L. Situation, Task, Action, Result, and Learning. The Learning component is the element most candidates omit — and the one that consistently differentiates strong from outstanding in NDIA scoring rubrics.
- Build your NDIS framework knowledge. Know the NDIS Act’s objects, the NDIS Code of Conduct’s seven obligations, the role of the NDIS Quality and Safeguards Commission, the structure of NDIS plans and review processes, and the current reform agenda. These are not background reading — they are live assessment areas in every NDIA interview.
- Practice out loud, with feedback. Reading your answers silently is not preparation. NDIA panels assess delivery as well as content — how you pace an answer, whether you use first-person language consistently, and whether you know when to stop. Mock interview sessions with expert feedback compress this learning significantly.
If you have your interview questions 24 hours in advance, that window is best spent structuring your STAR-L responses carefully — not writing scripts. Candidates who memorise scripted answers consistently deliver them stiffly and struggle when a panel member asks a follow-up question that their script did not anticipate.
