What Is a Behaviour Support Plan, and Why Is It Required?

A behaviour support plan sets out what is happening for a person, why it is happening, and what the people around them should do. Every participant receiving specialist behaviour support should have one, whether or not a restrictive practice is involved. It is built on a Functional Behaviour Assessment and reviewed at least every 12 months. Here is what each of those pieces actually means.

A behaviour support plan is a written document that explains what is happening for a person, sets out the best current understanding of why it is happening, and tells the people around them what to do. It is not a report about someone. It is a working instruction for the household, the school, the day program or the support team.

If you have behaviour support funding in an NDIS plan, the work it pays for runs in three parts. Assess, so that what is driving the behaviour is actually understood. Write a good plan, one that improves the person's quality of life and reduces behaviours of concern. Then implement it alongside the team supporting the participant, because a plan only changes anything once the people around the person are using it.

The two kinds of plan

Under the NDIS Rules, behaviour support plan means one of two documents, and they do different jobs.

An interim behaviour support plan is developed where there is a risk of harm, or a regulated restrictive practice is already in use, or both. Its purpose is to keep the person safe in the immediate term and to ensure their rights are not being restricted without a plan in place
A comprehensive behaviour support plan is the full plan, built on a completed Functional Behaviour Assessment, which explains the function of the behaviour and sets out the strategies that follow from it

The interim plan is not a draft of the comprehensive plan. It is a different document with a different purpose, and it exists because a thorough assessment takes months while safety and safeguarding cannot wait that long. Where a restrictive practice is already happening, the interim plan is also what brings it into the open, documents it, and constrains it while the assessment proceeds.

What is in a plan

The Rules require that a plan containing a regulated restrictive practice includes strategies that are evidence-based, person-centred and proactive, and that address both the person's needs and the functions of the behaviour. In practice a comprehensive plan we write covers the following.

A description of the person, what matters to them, and what a good day looks like
The behaviours of concern, described specifically enough that different people would agree on what they are seeing
The function of each behaviour, meaning the best current explanation of what it achieves for the person and what keeps it going
Proactive strategies, which are the changes to environment, routine, communication and demands that reduce the need for the behaviour
Skill development, so the person has another way to get the same outcome
Response strategies, which are what to do when the behaviour happens, written to be usable under pressure
Any regulated restrictive practice in use, clearly identified, with a plan to reduce and eliminate it
Who is responsible for what, how data will be collected, and when the plan will be reviewed

A plan that only contains response strategies is not a behaviour support plan. It is a containment procedure. The proactive and skill-building sections are where the actual change comes from.

What a Functional Behaviour Assessment Is

The Functional Behaviour Assessment, usually shortened to FBA, is the piece of work the comprehensive plan is built on. The NDIS Rules define it directly.

functional behavioural assessment means the process for determining and understanding the function or purpose behind a person's behaviour, and may involve the collection of data, observations, and information to develop an understanding of the relationship of events and circumstances that trigger and maintain the behaviour.

NDIS (Restrictive Practices and Behaviour Support) Rules 2018

The central idea is that behaviour is communication and it is doing a job. Behaviour that persists is being maintained by something, which means the useful question is not what is wrong with this person but what is this behaviour achieving and what is keeping it going.

The four functions usually described are escape or avoidance, gaining attention or connection, obtaining a tangible item or activity, and sensory regulation. A single behaviour can serve more than one function, and the same behaviour can mean different things in different settings, which is precisely why the assessment has to look at more than one setting.

What the assessment involves

Interviews with the people who know the person well, including family, support workers, teachers and other providers
Review of existing documents, meaning prior assessments, clinical letters, incident reports and previous plans
Direct observation in the settings where the behaviour actually happens, rather than only in a clinic room
Structured data collection by the people who are there, usually recording what happened before the behaviour, the behaviour itself, and what happened after
Analysis of that data for patterns across time, place, people, demands and physiological factors such as sleep, pain and hunger
Where relevant, screening for medical, sensory, communication and mental health contributors that the behaviour may be signalling

The output is a set of hypotheses about function, stated clearly enough to be tested. If the hypothesis is that a behaviour functions to escape a demand, then the plan's proactive strategies should reduce the demand or change how it is presented, and the data over the following months should show whether that was right.

This is also why the assessment is funded as part of the work rather than treated as preliminary paperwork. Intervention only produces change when it targets the actual function of the behaviour. Strategies chosen without that formulation are directed at the topography of the behaviour, meaning what it looks like, rather than at what maintains it, and the effect is at best neutral. A plan built on the wrong hypothesis can also make things worse, because a strategy that inadvertently reinforces the behaviour will strengthen it, and the usual response to strategies that appear not to be working is to escalate to a more restrictive one.

Put in clinical terms, the assessment establishes the treatment target. Everything downstream, meaning the strategies, the skill development, the training and the fade out plan, is only as sound as that formulation. Implementing a plan without it is intervening without a target, and there is no way to tell afterwards whether a result reflects the strategy or something else changing around the person.

This is why an FBA cannot be rushed and cannot be done by questionnaire alone, and why it is not optional. The behaviour support rules require the provider to undertake a behaviour support assessment, including a functional behavioural assessment, in developing a comprehensive plan. The NDIS Commission also publishes separate policy guidance and a practice guide on behaviour support assessment, setting out what it expects that assessment to involve.

Why a plan is required

There are two answers, one legal and one practical.

The legal answer is that behaviour support plans are a condition of registration for specialist behaviour support providers, set out in the NDIS (Restrictive Practices and Behaviour Support) Rules 2018. Where a regulated restrictive practice is used, the practice must be used in accordance with a behaviour support plan, the plan must be developed by a registered NDIS behaviour support practitioner, and the plan must be lodged with the NDIS Commission.

A regulated restrictive practice means one of five things under the Rules, and it is worth knowing the list because people are often using one without realising it has a name.

Seclusion, meaning sole confinement in a room or space where voluntary exit is prevented or implied not to be permitted
Chemical restraint, meaning medication used primarily to influence behaviour rather than to treat a diagnosed condition
Mechanical restraint, meaning a device used to restrict movement primarily to influence behaviour
Physical restraint, meaning physical force used to restrict movement primarily to influence behaviour
Environmental restraint, meaning restricting free access to parts of the environment, including items or activities

A locked pantry, a bedroom door held shut, a lap belt used outside its therapeutic purpose or a medication given to settle someone are all in scope. Each one requires a plan and, in most states, separate authorisation.

The practical answer is that behaviour support only works if it is consistent, and consistency across a household or a support team is impossible without a shared written document. A plan turns one practitioner's understanding into something twelve different people can implement the same way on a Tuesday night.

How a plan has to be developed

The behaviour support rules set out what developing a plan requires, and the obligations are about process rather than paperwork. In developing and reviewing a plan, the provider must take all reasonable steps to reduce and eliminate the need for restrictive practices, take prior assessments into account, make changes to the person's environment that may remove the need for restrictive practices, and consult with the person, with their family, carers or guardian, and with the providers who may use the practice.

Consultation is not a formality either. Where the intention is to include a regulated restrictive practice, the details have to be given to the person and their family in an appropriately accessible format.

What the behaviour support rules require

The requirements below are conditions of our registration as a specialist behaviour support provider. Breaching a condition of registration can attract a civil penalty, which is why these are treated as deadlines rather than aspirations.

On timeframes, where a regulated restrictive practice is in use and we are engaged as a result, the rules require the following.

The registration of the specialist behaviour support provider is subject to the condition that the provider must develop:

(a) an interim behaviour support plan that includes provision for the use of the regulated restrictive practice within 1 month after being engaged to develop the plan; and

(b) a comprehensive behaviour support plan that includes provision for the use of the regulated restrictive practice within 6 months after being engaged to develop the plan.

NDIS (Restrictive Practices and Behaviour Support) Rules 2018

Note the wording, which is six months after being engaged rather than six months after the first appointment. Engagement generally means the date of the service agreement, so delays in getting started eat into the window rather than extending it.

On review, the rules require the following.

The registration of a specialist behaviour support provider is subject to the condition that a comprehensive behaviour support plan developed by the provider that contains a regulated restrictive practice must be reviewed by an NDIS behaviour support practitioner:

(a) if there is a change in circumstances which requires the plan to be amended - as soon as practicable after the change occurs; or

(b) in any event - at least every 12 months while the plan is in force.

NDIS (Restrictive Practices and Behaviour Support) Rules 2018

Does this apply to every participant with behaviour support funding?

Yes for the plan itself. It is worth separating the two questions, because the plan and the deadlines come from different instruments.

The plan

As a registered specialist behaviour support provider, we are required to develop a behaviour support plan for every participant we deliver specialist behaviour support to, whether or not a regulated restrictive practice is involved. That obligation comes from the NDIS Practice Standards rather than from the Restrictive Practices Rules, and compliance with the Practice Standards is itself a condition of our registration under the NDIS (Provider Registration and Practice Standards) Rules 2018.

The supplementary module for specialist behaviour support applies to every provider registered to deliver the service, and it requires that each participant accesses behaviour support appropriate to their needs which incorporates evidence-informed practice and complies with the relevant legislation and policy frameworks. The NDIS Commission states the expectation directly in its guidance for specialist behaviour support providers, pointing to Schedules 3 and 4 of the Practice Standards Rules.

Every participant should have an up-to-date behaviour support plan that:

reflects their needs, improves their quality of life, and supports positive progress

aims to reduce and eventually eliminate any regulated restrictive practices, if applicable.

NDIS Quality and Safeguards Commission, Rules for specialist behaviour support providers and NDIS behaviour support practitioners

The Commission is also explicit that the rules for specialist behaviour support providers apply even when developing plans that do not include a restrictive practice. That is why a registered NDIS behaviour support practitioner has to develop the plan either way, and why the plan has to be built on assessment either way.

The deadlines

The one-month, six-month and 12-month timeframes are different. Those requirements in the behaviour support rules are written specifically for plans that contain a regulated restrictive practice, and that is what triggers them.

Where no regulated restrictive practice is involved, the Commission's stated position is that those timeframes do not technically apply, but should still be used as part of providing safe and quality services. Its practice guidance on monitoring and reviewing plans is likewise written for comprehensive plans generally rather than only for plans containing restrictive practices.

So the short version is that the plan is expected for everyone, the enforceable clock is tied to restrictive practices, and the Commission expects the same clock to be used regardless. Our practice is to apply it to every participant. A plan written a year ago and never revisited is out of date whatever the Rules technically compel.

Why the plan is reviewed every 12 months

A behaviour support plan is a set of hypotheses about why a behaviour is happening and what will help, written at a particular moment with the information available then. Over a year, the person changes, the people around them change, and the evidence about whether the plan is working accumulates.

Children and young people develop, and strategies that suited a nine-year-old rarely suit an eleven-year-old
Support workers, teachers, housemates and family circumstances turn over
Health, medication, sleep and communication change, and all of them change behaviour
Twelve months of incident and behavioural data reveal patterns that were invisible at the start
A fade out plan for a restrictive practice that is never revisited is a fade out plan in name only

The 12 months runs from the date the plan came into force, which is the date the practitioner finalised its development. Where several dates appear on the plan, the latest one applies. Fixing typos, adjusting a medication dose or making small changes to a skill development program does not reset that clock, because those are administrative updates recorded as an addendum or through version control.

A review must also happen sooner where circumstances change in a way that means the plan needs amending. The NDIS Commission gives three examples that generally qualify, being a pattern of unauthorised restrictive practices, a change in living arrangements, and a change in providers. In practice a new house, a new school, a new SIL provider, a hospital admission, a medication change or a serious incident are all reasons to bring the review forward.

What a review actually involves

A review is not a document refresh, and the Commission is explicit that superficial or administrative updates alone do not demonstrate that a review has occurred. It runs roughly in this order.

Consult the person and their support network on what is working, what is not, and what needs to change
Review recent incident reports and other information on behaviour, health and wellbeing, looking for patterns across the year
Revisit the behaviour support assessment, which can mean refining the functional hypotheses, changing the intervention approach, or identifying where further assessment is needed
Look again at the environment, and whether further changes there would reduce the need for restrictive practices
Evaluate progress on reducing and eliminating any restrictive practice, and where reduction has not progressed, document the barriers with clear actions, responsibilities and timeframes
Document the sources considered, the outcome, and the reasoning for changing or not changing the plan
Update the plan and any restrictive practice protocols, then train the people implementing it on what changed

Monitoring and review are different activities and it helps to keep them apart. Monitoring is the ongoing collection and analysis of information across the year, shared between us and the people implementing the plan. The review is where all of that is weighed up and acted on.

What we need from you

A plan and a review are only as good as the information that comes into them, and most of that information sits with the people who are with the person day to day rather than with us.

Behavioural data collected consistently through the year, not reconstructed the week before the review
Incident reports, including near misses and anything that was managed informally
Notice of changes as they happen, particularly moves, provider changes, school changes and medication changes
Time from the people who implement the plan, for consultation and for any retraining that follows
Any new reports from other professionals, such as a paediatrician, psychiatrist, speech pathologist or occupational therapist

If a restrictive practice has been used without authorisation, tell us. It is a change in circumstances that triggers an earlier review, and it is far better addressed openly than discovered later in incident data.

Funding, time and lodgement

Providers are responsible for planning their supports so that assessment, implementation support, monitoring and review can all be done properly across the life of the plan, and for allocating the time those activities take. Most of that work is not face to face. Data collection, analysis, document review, liaison, plan writing and lodgement are all legitimate and necessary parts of behaviour support delivery.

Where a plan containing a regulated restrictive practice is developed or reviewed, the plan must be lodged with the NDIS Commission as soon as practicable afterwards. The Commission generally treats two weeks from finalisation as practicable. Lodgement is required regardless of whether state or territory authorisation has been obtained yet, and separately from it.

Common misunderstandings

A behaviour support plan review is not the same as an NDIS plan review. One is about the document, the other is about funding, and they run on separate cycles
An FBA is not a diagnosis and does not replace one. It explains function, not condition
A stable year is not a reason to skip a review. Stability is a finding, and it is often the evidence needed to argue for reducing a restrictive practice
A new practitioner does not restart the six-month or 12-month clock. Both travel with the engagement and the plan
Six months is a maximum, not a target. Where the assessment is complete sooner, the plan should be written sooner

Where we work

In summary

A behaviour support plan explains what is happening, why it is happening, and what the people around the person should do. Every participant receiving specialist behaviour support should have one, whether or not a regulated restrictive practice is involved. The comprehensive version is built on a Functional Behaviour Assessment, which is the process of working out what a behaviour achieves and what maintains it, using interviews, observation across settings and structured data rather than assumption.

The timeframes are what the restrictive practice scoping applies to. Where a regulated restrictive practice is involved, the interim plan is due within one month of engagement, the comprehensive plan within six months, and the plan is reviewed at least every 12 months and sooner if circumstances change. We apply those timeframes either way.

If cost or funding is the barrier to getting this done properly, say so. Ask us about our reduced fee options. We are committed to making psychological therapy and assessment accessible.
