What is a Functional Behaviour Assessment?

A functional behaviour assessment, or FBA, is the first step in Positive Behaviour Support: an evidence-based clinical assessment that identifies why a behaviour is happening. It looks at the triggers, the function the behaviour serves, and the factors driving it, and it’s the foundation every effective behaviour support plan is built on.

If you’ve tried change after change and nothing’s worked, there’s usually a reason. The behaviour is happening for a cause that hasn’t been understood yet. Behaviour is almost always communication: an unmet need, a way of coping, a response to something around the person. An FBA is how we find that cause, instead of guessing at it.

To do that, we draw on more than one source. We gather information through structured observation across different settings, conversations with the participant, their family, carers and support workers, and a review of relevant records and history. The findings are written up in a clear, evidence-based report that becomes the foundation for the Comprehensive Behaviour Support Plan that follows.

Without a clear understanding of why a behaviour is happening, strategies tend to be hit-and-miss, and short-lived. The assessment is what makes the difference between guessing and genuinely helping. You can see where it fits in our full step-by-step process, and we conduct assessments in person across Perth and, where appropriate, by telehealth across regional WA.

Who is a functional behaviour assessment for?

If you’re trying to understand why a behaviour is happening, you’re already asking the right question. Here’s who an assessment is designed to help.

Families seeking clarity and direction

If you’re trying to understand a family member’s behaviour and why it happens, what it’s communicating, and what might actually help, an assessment gives you the clarity to move forward with confidence.

Participants with complex or escalating behaviours

When behaviours are becoming more frequent, more intense, or harder to manage, an assessment establishes a clear clinical baseline and points toward targeted, effective change.

Support Coordinators planning next steps

An assessment is the necessary first step before a Comprehensive Behaviour Support Plan can be developed, and it gives you clear, timely reporting to support your planning.

Schools and education settings

We work with schools and education staff to understand behaviour in the classroom and provide practical, achievable recommendations for educators and support staff.

Participants approaching a plan reassessment

A completed assessment provides strong clinical evidence to support a behaviour support funding request ahead of the next review.

Supportive knowledgeable team, with strong values and a clear focus on quality, collaboration and doing what’s best for Participants.

How a functional behaviour assessment works

A Functional Behaviour Assessment involves more than a single appointment. Here’s what to expect, from first contact to finished report.

  1. Getting started

    Get in touch and tell us what’s happening. We’ll match the person with a clinician experienced in their situation and confirm what’s involved.

  2. Gathering the full picture

    We don’t rely on one conversation. We observe behaviour where it actually happens, and talk with the participant, family, carers, and support workers because the people who know the person best hold important pieces of the puzzle.

  3. Looking across settings

    Behaviour often looks different at home, at school, and in the community. We look across those settings to understand what’s really driving it, not just where it shows up.

  4. Making sense of what we find

    Our clinician analyses everything gathered to identify the function of the behaviour, such as what need it’s meeting, what triggers it, and what keeps it going.

  5. Your assessment report

    You receive a detailed, clearly written report setting out the findings and recommendations. This becomes the clinical foundation for the Comprehensive Behaviour Support Plan.

We work with participants who have an active NDIS plan. Not sure whether funding is available for behaviour support? Get in touch and we’ll help you understand your options.

Trusted by families and professionals

When families need clarity around behaviours of concern, they want a provider who will take the time to really understand and explain it clearly.

We had the best services from Faith and Rex from Target Behaviour Support. They were reachable when we needed them and they gave us clear working behaviour strategies on how our team could be efficient. Their reports were timeous and above all they have been consistent. I recommend their services anytime.

We have had the pleasure of working with Faith... and her professionalism, clinical insight, and consistency have been outstanding. She communicates clearly, works collaboratively with support teams, and always keeps the participant’s needs at the centre of her practice.

I have had consistently excellent experiences with Target. They always go above and beyond for their participants and bring a genuine, person centred approach to every single situation. They collaborate so professionally. Communication is clear, timely, and focused on achieving the best outcomes - every time.

Leanne H

From the very start, the support has been outstanding, and our whole family is genuinely happy with how things are going. We really appreciate the dedication and the clear communication, and the difference it's made in such a short time has been remarkable. It's reassuring to finally feel this well looked after.

Rebecca T

We've achieved more in just a few months than we managed with our previous providers in years. The commitment and care really stand out, and it's been wonderful to watch the progress and the trust that's been built with our family. They genuinely go above and beyond, and we're so grateful for it.

They're always quick to respond when we reach out, and so understanding and supportive with it. They keep the person at the centre of everything and stay flexible whenever our needs change. Having someone this easy to work with has made a real difference.

Frequently asked questions

Everything you need to know about Functional Behaviour Assessments – what they involve, how long they take, and what happens when they're done.

What is a Functional Behaviour Assessment?

It’s the clinical process we use to work out why a behaviour is happening, such as identifying its function, triggers, and contributing factors through observation, conversations with the people who know the person, and a review of their history. The findings form the foundation of the behaviour support plan that follows.

Who is a Functional Behaviour Assessment suitable for?

It suits anyone whose behaviours of concern are getting in the way of everyday life, safety, or wellbeing, at any age, and across a wide range of conditions. Whether a behaviour is escalating, has appeared recently, or has been a long-standing worry, an assessment is the right starting point when you want to understand what’s really driving it rather than keep guessing.

How is a Functional Behaviour Assessment funded through the NDIS?

An FBA is funded through the NDIS, under the Capacity Building, Improved Relationships category. If you’re not sure whether the funding is in the plan, get in touch and we’ll help you check. Where there’s a clinical case, we can recommend behaviour support funding be added at the next plan reassessment.

What's the difference between a Functional Behaviour Assessment and a behaviour support plan?

They’re two stages of the same process. The assessment is the investigation. It works out why a behaviour is happening. The behaviour support plan is what comes next, taking those findings and setting out what to do about them. You need the assessment first, because a plan built without understanding the cause is just guesswork. Once the FBA is complete, it becomes the foundation for the Comprehensive Behaviour Support Plan.

Do you conduct assessments in person?

Wherever possible, yes. We conduct functional behaviour assessments in person across Perth, including in homes, schools, and community settings, and by telehealth for participants in regional WA. Doing the assessment where a behaviour actually happens gives us the clearest picture of what’s really going on.

How long does an assessment take?

Most assessments are completed within four to eight weeks of referral, depending on the complexity of the situation and how quickly we can gather information from the people who know the person. Where a behaviour is urgent and can’t wait, we can put an Interim Behaviour Support Plan in place so support starts straight away, while the full assessment continue

What happens after the assessment?

You’ll receive a detailed, clearly written report setting out what we found, what it means, and what we recommend. That report becomes the clinical foundation for the Comprehensive Behaviour Support Plan – the next step, where the findings turn into the practical strategies that support the person day to day. You can learn more about that here.

Understanding starts here.
