Understand PBS

What is Positive Behaviour Support?

Positive behaviour support (PBS) is a person-centred, evidence-informed approach to understanding behaviour and improving a person's quality of life. Rather than trying to simply stop a behaviour, PBS asks what the behaviour is communicating and what needs to change around the person so the behaviour becomes less necessary.

Under the NDIS, positive behaviour support is delivered by behaviour support practitioners and can be funded where behaviours of concern affect a person's safety, relationships, or participation in everyday life.

Who this is for

Families, NDIS participants, support coordinators, and support workers who want a clear, jargon-free explanation of what positive behaviour support actually involves.

Behaviour always means something

Behaviours of concern (things like aggression, self-injury, property damage, or withdrawal) usually serve a purpose for the person, even when that purpose isn't obvious. A behaviour might be a way of communicating pain, avoiding something overwhelming, seeking connection, or coping with an environment that doesn't fit the person's needs.

Positive behaviour support starts from curiosity rather than judgement. By understanding what a behaviour is doing for someone, we can look for safer, more effective ways for that need to be met, and change the conditions that make the behaviour more likely in the first place.

What positive behaviour support involves

PBS is a process, not a single intervention. It typically begins with getting to know the person and gathering information from the people who know them well, then developing strategies that fit the person's real life at home, school, work, or in the community.

  • Understanding the person, their history, communication, sensory needs, and environment
  • A functional assessment to understand why behaviours of concern happen
  • A behaviour support plan with proactive, preventative, and response strategies
  • Coaching and implementation support so the people around the person can use the plan consistently
  • Review and adjustment over time as things change

How PBS is different from just 'managing behaviour'

Managing behaviour often focuses on reacting in the moment. Positive behaviour support goes further: it aims to reduce the need for those moments by improving communication, building skills, adjusting the environment, and strengthening relationships.

Good PBS is also collaborative. The people who spend the most time with a participant, such as family members, carers, support workers, and teachers, are central to making strategies work. A plan that sits in a drawer changes nothing; a plan people understand and use can make a real difference to everyday life.

Is positive behaviour support right for your situation?

PBS can help when behaviours of concern are affecting safety, wellbeing, relationships, or a person's ability to take part in the things that matter to them. It may be especially relevant where restrictive practices are being used or considered, because reducing the need for restrictive practices is a core goal of behaviour support.

Every situation is different, and PBS is not a guarantee of any particular outcome. What it offers is a structured, respectful way to understand what's happening and work towards meaningful, lasting change.

Frequently asked questions

Who can access positive behaviour support through the NDIS?

Positive behaviour support can be funded where a participant has behaviours of concern and the support is reasonable and necessary in relation to their disability. Funding is usually found under Improved Relationships in a participant's plan. A support coordinator or the NDIS can help confirm what's available.

Does positive behaviour support try to eliminate behaviour?

No. The goal is to improve quality of life and reduce the need for behaviours of concern by understanding and meeting the underlying need. Often this leads to fewer or less intense incidents over time, but PBS focuses on the whole person, not just removing a behaviour.

How long does positive behaviour support take?

It varies. Understanding a person well and building strategies that genuinely work takes time, and plans are reviewed and adjusted as circumstances change. Some participants start with an interim plan and move to a comprehensive plan as more information is gathered.

Is PBS only about the person with disability?

Not at all. Because the people and environment around a person have a big influence on behaviour, PBS often involves coaching families, carers, and support teams so everyone can respond consistently and confidently.
