Families new to behaviour support are often surprised to learn there are two kinds of Behaviour Support Plan. You may be handed an interim plan within weeks, then told a comprehensive plan is still months away. That can feel like a delay, but the two plans are meant to work in that order.

The interim plan keeps people safe now. The comprehensive plan is written once the practitioner understands the person well enough to support lasting change.

The interim plan: safety first

An interim Behaviour Support Plan is a short document. According to the NDIS Quality and Safeguards Commission, it:

• clearly describes the behaviours of concern

• sets out general strategies to prevent those behaviours and to respond when they happen

• includes protocols to reduce the risk of harm to the person and to others

• states whether any regulated restrictive practice is to be used and, if so, when and how.

It is written before the full assessment is finished, so it does not try to explain why the behaviour happens. Its job is to give everyone supporting the person the same clear guidance while that work is done.

The comprehensive plan: understanding and change

A comprehensive Behaviour Support Plan is based on a behaviour support assessment, including a Functional Behaviour Assessment. The Commission describes it as a holistic document that:

• addresses the underlying reason, or function, of the behaviour

• outlines changes needed in the person's environment, such as at home, school or work

• provides skill development programs so the person can learn other ways to meet their needs

• includes response strategies for when the behaviour does occur

• identifies when and how any regulated restrictive practices will be reduced and stopped.

In short, the interim plan manages risk, and the comprehensive plan aims to improve the person's quality of life.

When each plan is due

Under the NDIS (Restrictive Practices and Behaviour Support) Rules 2018, a specialist behaviour support provider must develop:

• an interim plan within one month of being engaged

• a comprehensive plan within six months of being engaged.

A provider counts as engaged from the date of the service agreement, or from a later start date written into that agreement.

There is one detail worth knowing. The Commission states that these timeframes apply by law to plans containing regulated restrictive practices. For plans without restrictive practices, it expects providers to use the same timeframes as a guide to safe, quality practice.

Lodgement and review

A plan that contains a regulated restrictive practice must be lodged with the NDIS Commission. A plan without restrictive practices does not need to be lodged.

Comprehensive plans that include regulated restrictive practices must be reviewed at least every 12 months, or earlier if the person's circumstances change. The Commission also describes regular checking of whether strategies are working as good practice for any plan.

If you change providers

You are free to change behaviour support providers. In February 2026 the Commission clarified what a new provider must do so that support continues.

• No existing plan: the new provider starts with an interim plan.

• An interim plan already exists: the new provider can move on to the comprehensive plan, once they have confirmed the interim plan is still current, suits the person's immediate needs and manages risk. The comprehensive plan is still due within six months of the new provider being engaged.

• A comprehensive plan already exists: if it is still current and suits the person's needs, the new provider can go ahead with training and implementation support. They do not have to write another interim plan, but they must review the plan when circumstances change and at least every 12 months.

Questions worth asking your provider

• When does our service agreement say you start, and when will we see the interim plan?

• Who will you speak with while preparing the comprehensive plan?

• Does the plan include any restrictive practices and, if so, what is the plan to reduce them?

• Who will train our family and support workers to use the plan?

• When will the plan next be reviewed?

How Dawnability approaches plans

Dawnability develops both interim and comprehensive Behaviour Support Plans in line with NDIS Quality and Safeguards Commission requirements. Plans are written with participants, families and support teams, and reviewed as needs change. We also provide training so that families, carers and support staff can use the strategies with confidence.

We work with children, young people, adults, and older adults across Canterbury-Bankstown, South-West Sydney and Greater Western Sydney, and across Australia, with English and Arabic-speaking staff available.
