What is the difference between a behaviour support practitioner and a psychologist?

Considering a career in Positive Behaviour Support? This article breaks down the differences between behaviour support practitioners and psychologists.
Roles compared: PBS practitioner vs psychologist
Behaviour support practitioner focus areas
Positive Behaviour Support (PBS) practitioners focus on improving quality of life through understanding and addressing behaviours of concern using person-centred, evidence-based approaches.
Our work is about behaviour in context, what it communicates, what is triggering it, and what needs to change around the person to help improve their quality of life.
We look at routines, environments, sensory needs, stress, communication, skill gaps, and the way support teams respond.
The focus is practical, hands-on, and centred on everyday life. Behaviour support practitioners do not diagnose mental health conditions or provide therapy. Our scope is behaviour and quality of life support, and PBS practitioners also have an important role in upholding human rights within state and federal law by identifying, reducing and eliminating the use of restrictive practices.
Psychologist focus areas
Psychologists focus on understanding how thoughts, emotions, and behaviour influences a person's mental health and wellbeing. They assess, diagnose and treat mental health conditions using evidence-based therapies such as Cognitive Behavioural Therapy (CBT), Acceptance and Commitment Therapy (ACT), Dialectical Behaviour Therapy (DBT) and other psychological interventions.
Psychologists help people develop insight into how their thoughts, emotions and behaviours interact with the aim of increasing psychological flexibility. They also help others process trauma and life experiences, strengthen coping skills, improve emotional regulation, and work towards meaningful personal goals. They are also competent in performing cognitive, personality and diagnostic assessments and provide recommendations across a range of settings, including health, education and disability services. Their work is primarily clinically focused and seeks to understand and address the internal psychological factors that influence a person's functioning and wellbeing.
Collaboration
At times, behaviour support practitioners and psychologists may work together to support a client, however, each profession operates within different scopes of practice and works toward different therapeutic and behavioural outcomes. For example, a behaviour support practitioner may develop practical strategies to reduce behaviours of concern, whereas a psychologist addresses underlying factors such as anxiety, trauma or emotional regulation. When both professionals coordinate their approaches, they can address the client’s needs more comprehensively, leading to more sustainable and enduring change.
Overlap
Sometimes, a person might be both a PBS practitioner AND a psychologist. This means, as a PBS practitioner, they have been approved by the NDIS to provide behaviour support, and they are appropriately degree qualified as a psychologist, and a member of AHPRA.
If you're considering a career in Positive Behaviour Support, it's important to understand the distinction between these professions. Depending on your qualifications and experience, you may be eligible to work as a PBS practitioner, a psychologist, or both.

Responsibilities of PBS practitioners compared with psychologists
Positive Behaviour Support (PBS) is an evidence-based framework used across disability, education, early intervention, aged care and mental health settings. However, NDIS Specialist Behaviour Support is a distinct, regulated role. Practitioners providing Specialist Behaviour Support to NDIS participants must meet the suitability requirements of the NDIS Quality and Safeguards Commission (NQSC) and work within the NDIS behaviour support framework.
Outside the NDIS, PBS principles may also be applied in private and community settings, including behavioural intervention approaches which have different practice frameworks and training pathways, such as Applied Behaviour Analysis (ABA).
Psychology is a registered health profession with practitioners working across private practice, hospitals, schools, community mental health, government services and the NDIS. The sections below outline the typical responsibilities of NDIS behaviour support practitioners and psychologists.
How PBS practitioners support NDIS participants
When supporting NDIS participants, behaviour support practitioners:
- Build rapport and develop collaborative relationships with participants, families, carers, allied health and support teams;
- Identify and address the reasons behind behaviours of concern and the factors influencing wellbeing and quality of life;
- Complete comprehensive assessments, including functional behaviour assessments, observations, interviews and data analysis;
- Develop Comprehensive Behaviour Support Plans tailored to the participant's individual goals, needs and circumstances;
- Provide coaching, education and practical training to families and support teams;
- Monitor progress through data collection, regular review and ongoing evaluation;
- Adapt strategies as the participant's needs and goals change over time;
- Promote participant rights, choice, dignity, independence and quality of life;
- Where required, support the reduction and elimination of restrictive practices in accordance with the requirements of the NDIS Quality and Safeguards Commission.
What psychologists typically focus on
- Assess psychological, emotional, cognitive, and behavioural functioning;
- Assess and, where appropriate, diagnose mental health conditions (within scope of practice and competence according to areas of expertise);
- Deliver evidence-based psychological therapies (e.g. CBT, ACT, DBT-informed approaches);
- Support emotional regulation, coping skills and psychological flexibility;
- Treat anxiety, depression, trauma and other mental health concerns;
- Help participants process difficult life experiences and build resilience;
- Improve self-esteem, confidence and emotional wellbeing;
- Support participants to understand the relationship between their thoughts, emotions and behaviours;
- Complete standardised cognitive, behavioural and psychological assessments (e.g., Wechsler Adult Intelligence Scale (WAIS-IV), Wechsler Intelligence Scale for Children (WISC-V), Autism Diagnostic Observation Schedule (ADOS-2), Brown Executive Function/Attention Scales etc;
- Develop strategies to improve relationships and interpersonal functioning;
- Collaborate with families, carers and other professionals to provide a systemic service to facilitate participant outcomes;
- Provide reports and recommendations to inform NDIS planning and other supports;
- Support participants to achieve NDIS goals and improve their overall functioning and quality of life.

Qualifications: education and training differences
PBS practitioner pathways
There is no single university degree or prescribed training pathway required to become a behaviour support practitioner. Instead, the profession welcomes people from a broad range of disciplines, including psychology, social work, occupational therapy, speech pathology, education, counselling, disability, nursing and other human services backgrounds. Applicants may also have developed relevant skills through experience, behavioural science, data analysis or extensive experience supporting people with disability.
To provide Specialist Behaviour Support to NDIS participants, practitioners must be assessed as suitable by the NDIS Quality and Safeguards Commission (NQSC) in accordance with the NQSC PBS Capability Framework. Without NQSC suitability, practitioners cannot deliver Specialist Behaviour Support services under the NDIS.
Once approved, behaviour support practitioners are expected to participate in regular supervision, self-assessment, reflective practice and ongoing professional development to maintain and strengthen their capability throughout their careers.
Psychologist training pathways
Becoming a psychologist follows a formal and regulated training pathway. This typically begins with either a three-year accredited undergraduate psychology degree or, for those who already hold a bachelor's degree in another discipline, an APAC-accredited Graduate Diploma in Psychology. Both pathways are then followed by a fourth year of psychology, usually an Honours degree or equivalent.
Graduates then choose one of two pathways to general registration. The 5+1 internship pathway involves completing an APAC-accredited fifth-year qualification, such as a Master of Professional Psychology, while provisionally registered, followed by a one-year supervised internship and successful completion of the National Psychology Exam. Alternatively, graduates can complete an APAC-accredited postgraduate professional psychology program incorporating fifth and sixth year training, typically through a two-year master’s degree, combined master’s and PhD, or doctorate. These programs may be offered in areas such as Clinical, Counselling, Educational and Developmental, Organisational or Health Psychology; however, obtaining an area of practice endorsement further requires completion of a registrar program after gaining general registration.
The time required to become a psychologist registered with the Australian Health Practitioner Regulation Agency (AHPRA) varies depending on the entry pathway chosen, but generally involves around six years of accredited psychology education and supervised training. Registered psychologists must also meet ongoing professional development, ethical and registration requirements throughout their careers.
Career overlap
In some circumstances, a person can be both a behaviour support practitioner AND a psychologist. For example, a number of our psychologists at Ability Consultants are also behaviour support practitioners, and they provide both services to our clients.
Every practitioner at Ability Consultants is approved by the NQSC to provide Positive Behaviour Support services. Psychology services, however, are only provided by appropriately qualified psychologists who are registered with the Australian Health Practitioner Regulation Agency (AHPRA).
How Ability Consultants supports both roles
We support employees working across psychology and Positive Behaviour Support through flexible work arrangements, structured supervision opportunities and ongoing professional development. Our collaborative environment provides opportunities to learn from a diverse range of experienced practitioners and strengthen clinical skills.
- Flexible working hours for all PBS practitioners, psychologists and those currently studying psychology;
- Working with experienced PBS practitioners and psychologists;
- High-quality PBS training and ongoing learning and professional development;
- Clinical supervision and mentoring;
- Opportunities to build skills across both psychology and Positive Behaviour Support;
- Regular peer learning, case discussions and reflective practice;
- Clear career progression and opportunities to develop clinical expertise.
Psychologists (both provisional and general registered) who are employed on a full-time contract are expected to complete a minimum of 20 hours per week client-billable hours.
For provisional psychologists, hours outside of the minimum 20 hours of client-billable are utilised to complete the psychology internship requirements including professional development and case reports as required under the AHPRA registration guidelines.
Psychologists employed as contractors (not on a salary or full-time employment) are required to complete a minimum of 10 hours per week client-billable hours.

Which role is right for you?
How to choose between PBS practitioner and psychologist
Choosing between a career in Positive Behaviour Support and psychology depends on your interests, qualifications and long-term career goals. While both professions support people to improve their quality of life, they differ in their scope of practice, training pathways and day-to-day responsibilities.
Hybrid paths
Some professionals choose to become both psychologists and NDIS behaviour support practitioners. If you're already a qualified psychologist, or currently completing your psychology training, it is possible to become a behaviour support practitioner by meeting the NDIS Quality and Safeguards Commission's suitability requirements.
This allows practitioners to work across two complementary but distinct professions, each with its own scope of practice. At Ability Consultants, we welcome clinicians who bring expertise across both disciplines and support ongoing professional development for those interested in expanding their career into Positive Behaviour Support.
While some of our clinicians are qualified in both professions, each service is delivered within its own professional scope to ensure high-quality, ethical and participant-centred care.
