How to become an NDIS Positive Behaviour Support Practitioner

If you're passionate about helping people with complex behaviours of concern and want to specialise in contemporary, ethical behaviour support, becoming an NDIS Positive Behaviour Support Practitioner can be a highly rewarding career path. Positive Behaviour Support (PBS) is person-centred, evidence-based, and aimed at improving quality of life within the framework of the National Disability Insurance Scheme (NDIS).

However, this isn't a title you can simply adopt without meeting specific suitability requirements set by the NDIS Quality and Safeguards Commission. The process involves developing the right skills, gaining experience, and demonstrating your capability through an official application process. Here's an overview.

1. Understand the Role and Scope

An NDIS behaviour support practitioner is recognised as someone who can conduct Functional Behaviour Assessments (FBAs), develop Positive Behaviour Support Plans (PBSPs), support people with disability, their families, carers, and support teams, and guide the implementation and review of PBS strategies.

This work is regulated: you must be considered suitable by the NDIS Commission to practice in this role. Until then, you cannot undertake behaviour assessments or develop behaviour support plans - even under supervision.

2. Build Relevant Qualifications and Skills

While the NDIS doesn't legally mandate specific degrees for PBS practitioner suitability, most practitioners hold qualifications or strong experience in fields such as psychology, social work, occupational therapy, behavioural science, nursing, special education or disability-related disciplines, or accredited PBS-related or behaviour analysis training.

These qualifications demonstrate foundational knowledge in human behaviour, learning theory, and ethical practice — all key to effective PBS. Additional specialised training, such as Applied Behaviour Analysis (ABA) or postgraduate PBS courses, can further strengthen your capability.

3. Know the PBS Capability Framework

The Positive Behaviour Support Capability Framework outlines the knowledge, skills, and professional behaviours expected of PBS practitioners. It's used by the NDIS Commission as a benchmark in the suitability assessment.

4. Practitioner Levels

In Positive Behaviour Support, there are four recognised practitioner levels - Core, Proficient, Advanced, and Specialist. Each level represents progressively deeper knowledge, broader experience, and higher-level problem-solving skills within the PBS Capability Framework. Core practitioners are entry-level and typically work under supervision, while Proficient practitioners have built experience and can undertake more complex assessments and planning. Advanced practitioners demonstrate high-level analytical, leadership, and strategic skills, and Specialist practitioners combine advanced PBS expertise with depth in a specific area such as trauma, dual diagnosis, or culturally specific practice.

These capability levels are not formally "endorsed" by the NDIS Commission; rather, the Commission uses tools like the PBS Endorsement Tool and your evidence portfolio to assess whether you meet the skills and experience required to be considered suitable to practice within your scope. Typically, your supervisor will sign off on what level practitioner you are and guide your professional development towards moving to the next level.

5. Gain Practical Experience

Real-world experience working with people who require behaviour support is essential for developing competence in Positive Behaviour Support practice. This experience may come from roles within disability services or mental health settings, where practitioners support individuals with complex needs and behaviours of concern, and progressively build skills in conducting assessments, collecting meaningful data, and implementing behaviour support plans.

6. Complete the Suitability Assessment

To become an NDIS Behaviour Support Practitioner, you must: self-assess your skills against the PBS Capability Framework, prepare a portfolio of evidence demonstrating your skills, qualifications, experience, and reflective practice, and apply via the NDIS Commission's online portal.

At Therapy Coalition, we welcome practitioners who are Proficient level and above.

There are two pathways: Self-assessment pathway — for experienced practitioners with a strong evidence portfolio, and Alternative entry-level pathway — for those newer to the field with limited evidence but demonstrable capability.

You'll need an NDIS Worker Screening clearance number and all relevant documentation to avoid delays. Once submitted, the NDIS Commission aims to process applications within a few weeks.

7. Work Within Your Scope and Continue to Grow

Once deemed suitable, you can practice as a PBS Practitioner. You must continue to practice within your scope and engage in ongoing professional development. Supervision and reflective practice are also expected parts of maintaining capability in this field.
