NDIS Plan Review vs Plan Reassessment: What’s the Difference?

If you’ve spent any time navigating the NDIS, you’ve probably come across the terms “plan review” and “plan reassessment” and wondered — are these the same thing? A trick question? Some kind of bureaucratic wordplay designed to test your patience?

You’re not alone. This is one of the most common points of confusion for NDIS participants, carers, and even some support workers. The good news? Once you understand the difference, everything becomes much clearer. And that’s exactly what this article breaks down.

First Things First: The Terminology Has Changed

Before anything else, it’s important to know that the NDIS updated its language. From 3 October 2024, the NDIS made changes to how reassessments work, and what was previously called a “plan review” is now officially referred to as a “plan reassessment.”

So if you’ve been Googling “plan review” and getting confused by results that say “reassessment,” that’s why. They’re referring to the same process — just with a new name.

Reviews are now referred to as NDIS Plan Reassessments or Plan Variations, and they’re essential to ensure that your support aligns with your current needs and goals.

What Is an NDIS Plan Reassessment?

A plan reassessment is the full, comprehensive review of your NDIS plan. Think of it as the big one — a thorough look at your supports, goals, funding, and circumstances.

A reassessment is a comprehensive examination of your plan. It can occur either at a scheduled time — typically 12 to 36 months after your initial plan — or unscheduled, at your request. This thorough evaluation allows for adjustments to better reflect changes in your circumstances.

In simple terms, a plan reassessment is when the NDIA creates a new plan with a new end date. That’s the key takeaway — a reassessment replaces your current plan with a fresh one.

During a reassessment, the NDIA goes through your goals, your daily living needs, your support requirements, and any changes in your life. Your plan reassessment experience will start with a participant check-in, where the NDIA contacts you near your current plan end date to book your reassessment meeting. As part of this call, they will check in with you and see how you are going with your current NDIS plan, and if your circumstances have changed.

You can have the meeting face-to-face, over the phone, or via video call. You can also bring along a family member, carer, or support coordinator. No one has to go through this alone.

What Is an NDIS Plan Variation?

A plan variation is the lighter-touch option. It’s for when you need a smaller change to your plan — without the need to go through a full reassessment.

A plan variation is when the NDIA changes the existing plan — as opposed to replacing it entirely. The plan itself stays the same; only specific parts are adjusted.

Reasons for a plan variation include: correcting a minor or technical error, changing the reassessment date of the plan, making a change to the statement of participant supports in relation to managing the funding for supports, or making a change to an existing stated support to reflect a different provider or manner of delivery.

So if you want to switch providers, adjust how your funding is managed, or fix an admin error, a variation is likely all you need. No need to trigger a full reassessment for something that can be sorted out with a small tweak.

Scheduled vs Unscheduled Reassessment: What’s the Difference?

This is where it gets a bit more layered. Reassessments come in two types.

Scheduled Reassessment — This happens at the end of your plan period. Your first NDIS plan reassessment usually falls 12 months after your plan started. The NDIA will normally contact participants or your authorised representatives 3 months before a plan reassessment is due and confirm details. If you haven’t heard from them six weeks prior, give them a call on 1800 800 110.

Unscheduled Reassessment — This one is triggered by you (or sometimes the NDIA) when something significant changes in your life. Circumstances that may lead to a participant requesting a plan variation or reassessment include a change in a participant’s impairment, such as a deterioration of functional capacity, a change in their family or informal support network, or an updated assessment recommending different care, support, or assistive technology.

In short: scheduled = expected, unscheduled = when life happens.

What Triggers an NDIS Plan Reassessment?

Life doesn’t pause while your plan ticks along. So the NDIS does allow you to request a reassessment outside of your scheduled date.

Common triggers include:

• A significant change in your health or disability-related support needs
• Changes in your living arrangements (such as moving out of home or into supported accommodation)
• Loss of informal supports like a family carer becoming unavailable
• Major life transitions — starting school, leaving school, starting work, or retiring from work
• New medical or therapy assessments recommending different supports

If you lodge a request for a plan change reassessment without clear evidence, it may be declined. To help the process, make sure you have your evidence ready before you make a request for a plan change reassessment.

And importantly — overspending your budget before the end of your plan funding period is not, by itself, a valid reason for a reassessment. The NDIS is pretty clear on that point.

What Is a S48 Review? And How Does It Relate?

You might have heard people mention a “S48 review” and wondered what that means. This one has a legal flavour to it.

If you have a change in circumstance which means your present plan or funding is no longer adequate for the new situation, you can apply at any time for a plan variation or “change of circumstances review,” known internally as a S48 review.

The “S48” refers to Section 48 of the NDIS Act 2013. A participant can request a change of their NDIS Plan at any time under Sections 47A and 48 of the NDIS Act. The NDIA will determine whether the request should be considered a variation of the plan under Section 47A, or a reassessment of the plan under Section 48.

So when you hear “S48 review,” it basically means a formal unscheduled reassessment request — usually because something significant has changed. It’s the same process, just referred to by its legal clause. The NDIA has 21 days to make a decision about whether to conduct a Section 48 plan review.

Can You Request a Reassessment at Any Time?

Yes — and this is really important for participants to know. If you need changes to your plan before the reassessment date, you can contact the NDIA at any time to ask about making changes to your plan.

However, the NDIA decides whether your request qualifies for a full reassessment or just a variation. Sometimes you might not need any changes, but just more help to implement your plan. Other times, the NDIA might be able to vary your plan without doing a full reassessment or replacing it with a new one.

The NDIA tries to work with you on this — they won’t just shut the door in your face. But you do need to come prepared with evidence.

What About Longer Plan Durations?

Not every participant needs a plan reviewed every 12 months. If your situation is stable, you can ask for a longer plan.

Participants are able to request plan durations of up to three years. These longer-term plans are designed for participants who are in a stable situation with support needs unlikely to change, confident in using their funding to pursue their goals, and focused on learning new skills, employment, or becoming more active in the community.

For young children, things are a bit different. For children younger than 7, a plan length of 12 months is recommended due to the major changes in early childhood. Sometimes a plan of up to 24 months can be done for young children, if it is better aligned with important transition points and milestones.

What Happens If You’re Unhappy With the Outcome?

Sometimes a reassessment doesn’t go the way you hoped. That’s frustrating — but you do have options.

You can request an internal review within 3 months. If still unhappy, you can apply for an external review at the Administrative Review Tribunal (ART), usually within 28 days.

If the NDIA is unable to decide within 21 days of whether or not they will do a plan reassessment or variation, an internal review will occur automatically.

The process has layers — but they exist to protect you. Having a support coordinator, advocate, or someone like the team at Healthy Support WA in your corner can make a real difference when navigating these steps.

A Note on What’s Changing in 2025 and Beyond

The NDIS is in a period of ongoing reform. Changes to the NDIS Act made in October 2024 enabled a new way of planning that is more consistent and focuses on a person’s disability support needs. The aim is for the first participants to begin using the new planning approach from mid-2026.

Participants will still be able to request a reassessment or variation of their plan if their circumstances change, and will continue to have the right to request a review of their plan, including through the Administrative Review Tribunal.

The terminology and rules may continue to evolve — which is all the more reason to stay informed and work with knowledgeable NDIS support providers who keep up with these changes.

Getting Support Through the Process

Navigating NDIS plan reassessments doesn’t have to feel like a solo mission. NDIS Support Coordination services can help you prepare your evidence, understand what type of review you need, and make sure your plan genuinely reflects your life and goals.

Whether it’s your first reassessment or you’ve been through the process before, having someone in your corner who understands the system makes the whole thing far less overwhelming. And if something doesn’t go your way, they can help you navigate the review and appeal process too.
