How to Write a Behaviour Support Plan - A Practical Guide

A behaviour support plan (BSP) is one of the most important documents in disability support. Done well, it provides a clear framework for understanding why behaviours of concern occur and outlines evidence-based strategies to improve quality of life. Done poorly, it becomes a shelf document that nobody reads, let alone follows.

This guide walks through the key components of a BSP, the data collection process, and the NDIS requirements you need to meet. Whether you are a behaviour support practitioner writing your first plan or a provider overseeing plan quality, this will help you create plans that actually work.

What is a behaviour support plan under the NDIS?

A behaviour support plan is a documented framework developed by a registered practitioner that identifies why behaviours of concern occur and outlines evidence-based strategies to address them. Under the NDIS, BSPs containing restrictive practices must be lodged with the NDIS Quality and Safeguards Commission within one month of implementation, and all BSPs must be reviewed at least annually.

The fundamental principle is this: behaviour always serves a function. People do not engage in behaviours of concern without reason. A good BSP identifies those reasons and provides better alternatives.

How do you conduct a functional behaviour assessment?

What are the four main functions of behaviour?

Behaviour analysis research identifies four primary functions that explain why behaviours of concern occur. Correctly identifying the function is essential because strategies that work for one function may worsen behaviour driven by another. The four functions are escape, attention, access to tangibles, and sensory regulation.

• Escape or avoidance - the person wants to get away from a situation, demand, or sensory input
• Attention - the person wants social interaction, connection, or a response from others
• Access to tangibles - the person wants a specific item, activity, or preferred outcome
• Sensory regulation - the behaviour provides sensory input that the person finds regulating or relieving

How should you define behaviours of concern in a BSP?

Every behaviour of concern in a BSP must be described in observable, measurable terms that any support worker can understand without interpretation. Vague labels like "becomes aggressive" or "has a meltdown" are not acceptable under the NDIS Practice Standards. Specific descriptions ensure consistent data collection and reliable measurement of whether strategies are working.

• "Strikes others with an open hand on the upper body" (not "is violent")
• "Leaves the premises without informing staff" (not "absconds")
• "Pulls at own hair on the crown of the head using both hands" (not "self-harms")

For each behaviour, include the current frequency (how often it occurs), intensity (the severity of each episode), and duration (how long episodes typically last). This baseline data is essential for measuring whether your plan is working over time.

What proactive strategies should a BSP include?

Proactive strategies aim to prevent behaviours of concern from occurring in the first place and should form the largest section of any BSP. The NDIS Commission expects proactive strategies to make up at least 80% of a plan's content, with reactive strategies and restrictive practices as a last resort only. Effective proactive strategies include:

• Environmental modifications: Adjusting lighting, noise levels, routine structures, or physical spaces to reduce triggers
• Skill building: Teaching the participant communication skills, coping strategies, or alternative behaviours that serve the same function
• Schedule adjustments: Ensuring adequate breaks, preferred activities, and predictable routines
• Relationship-based strategies: Building rapport, offering choice, and maintaining consistent staffing where possible

How do you write reactive strategies for a BSP?

Reactive strategies describe what staff should do when behaviours of concern occur despite proactive measures. Effective reactive strategies are specific, sequenced, and prioritise safety while maintaining the participant's dignity. A well-written reactive strategy reads like a step-by-step guide that any staff member can follow in the moment.

Good reactive strategies are specific and sequenced. For example: "If [participant] begins striking, staff should step back to arm's length, use a calm and low tone of voice, offer two choices ('Would you like to go to your quiet room or sit in the garden?'), and allow 30 seconds for a response before repeating."

What data collection is required for an NDIS behaviour support plan?

The NDIS Commission requires ongoing data collection to demonstrate that BSP strategies are being implemented and are effective. As of 2026, practitioners must submit monthly reports on restrictive practice use, and best practice involves reviewing behaviour data at least monthly. Your plan should specify:

• What data support workers need to collect (incident frequency, duration, intensity, triggers)
• How often data will be reviewed (monthly at minimum)
• Who is responsible for reviewing the data and updating the plan
• Criteria for plan review (e.g., if behaviour frequency increases by 25% over two weeks, an interim review is triggered)

Make data collection as simple as possible for support workers. Complex data sheets with 15 fields rarely get filled out accurately in the middle of a shift. A brief, structured incident form that takes 2 to 3 minutes to complete will yield much better data than an elaborate system that nobody uses.

What are the NDIS compliance requirements for behaviour support plans?

The NDIS Quality and Safeguards Commission has six key compliance requirements for behaviour support plans as of 2026. Non-compliance with any of these requirements can result in conditions on a provider's registration or enforcement action against the practitioner.

1. BSPs must be developed by a registered behaviour support practitioner who is enrolled with the Commission
2. Plans containing restrictive practices must be lodged with the Commission within one month
3. Practitioners must submit monthly reports on the use of restrictive practices to the Commission
4. BSPs must be reviewed at least annually, or sooner if circumstances change
5. There must be evidence of participant and family involvement in the development and review of the plan
6. All staff implementing the BSP must receive training on the plan's contents and strategies

What does a good behaviour support plan look like?

A well-written BSP is clear enough that a new staff member could read it and understand exactly what to do within 15 minutes. It should be written in plain language, avoid jargon, and include practical examples. If your support workers are not reading or following the BSP, the plan needs to be simpler, not more detailed.

The ultimate measure of a BSP's quality is whether it improves the participant's quality of life and reduces the need for restrictive practices over time. If behaviour frequency is not decreasing after 3 to 6 months of consistent implementation, it is time to revisit your functional assessment and consider whether the identified function is accurate.
