Functional Behaviour Assessments (FBA) play a central role in Behaviour Support. They provide clear insight into why behaviours occur. This insight allows support teams to build effective and practical Behaviour Support Plans.
At Access Your Supports, FBA forms the foundation of every structured and person-centred approach to Behaviour Support.
What Is a Functional Behaviour Assessment?
A Functional Behaviour Assessment is a structured process. It identifies the purpose behind a behaviour. It examines three key elements:
- What happens before the behaviour
- What the behaviour looks like
- What happens after the behaviour
This process helps teams understand what the behaviour is trying to communicate. It moves the focus from stopping behaviour to understanding it.
Why Effective Support Plans Depend on FBA
An effective Behaviour Support Plan must address the cause of behaviour. Without this understanding, strategies may not work.
For example, a person may use behaviour to avoid a task. Another person may use behaviour to gain attention or respond to sensory input. These behaviours may look similar, but they require different support strategies.
An FBA identifies the function of the behaviour. This allows support teams to match strategies to the correct need. As a result, plans become more effective, consistent, and safe.
How Functional Behaviour Assessments Shape Support Plans
FBA directly informs how a Behaviour Support Plan is developed. At Access Your Supports, this process follows a clear structure.
1. Identify the Function of Behaviour
The assessment determines why the behaviour occurs. This may relate to communication, environment, or unmet needs.
2. Match Strategies to the Function
Support strategies are selected based on the identified function. This ensures the response is relevant and effective.
3. Introduce Skill Development
Plans include teaching new skills. These may include communication, emotional regulation, or daily routines.
4. Adjust the Environment
Changes to the environment can reduce triggers. This may involve routines, expectations, or sensory inputs.
5. Create Consistency Across Supports
Everyone involved follows the same plan. This includes family members, carers, and other professionals.
This structured approach leads to clear and reliable support.
A Practical Example
A person may show aggressive behaviour during tasks. Without an FBA, support may focus on stopping the behaviour.
With an FBA, the team may identify that the behaviour helps the person avoid difficult tasks. The plan can then:
- Adjust task difficulty
- Introduce breaks
- Teach the person to request help
This approach addresses the cause, assists in reducing behaviour and helps build useful skills.

A Person-Centred Approach
At Access Your Supports, Behaviour Support focuses on the individual. Every plan reflects the person’s needs, goals, and preferences.
FBA supports this approach by:
- Identifying unmet needs
- Understanding communication styles
- Highlighting strengths and challenges
This ensures that support plans improve quality of life. The goal is to reduce behaviours of concern and build independence.
The Role of Environment and Communication
Behaviour often connects to the environment and communication.
A person may feel overwhelmed in certain settings. They may also struggle to express needs clearly.
AYS Behaviour Support Practitioners assess:
- Home, school, and community environments
- Communication methods and challenges
Simple adjustments can improve outcomes. These may include clearer instructions, visual supports, or changes to routine.
Working With Allied Health and Support Teams
Functional Behaviour Assessments often involve collaboration. A team approach improves consistency and results.
Access Your Supports may work alongside:
- Psychology to support emotional regulation
- Occupational Therapy to address sensory needs
- Support Coordination to organise services and supports
Access Your Supports Behaviour Support Practitioners are qualified and registered professionals. You can learn more about the team and their experience on our Behaviour Support team page.
Building Confidence and Independence
Effective Behaviour Support Plans focus on long-term outcomes. They aim to build skills that support independence.
FBA helps identify areas for growth, such as:
- Communication skills
- Emotional regulation
- Daily routines
Support plans then include strategies to build these skills over time. This leads to improved confidence and participation in daily life.
How to Get Started
