Understanding Functional Behaviour Assessment and Its Role in NDIS Plans

Introduction

Functional behaviour assessment (FBA) represents a systematic, evidence-based approach that transforms how NDIS participants, families, and support workers address challenging behaviours. For individuals enrolled in the National Disability Insurance Scheme (NDIS), understanding the role of functional behaviour assessment in developing comprehensive support plans proves essential for achieving positive behaviour support outcomes and improving quality of life.

At Nurse Aid Australia, our experienced behaviour support practitioners recognise that challenging behaviours serve specific functions and communicate unmet needs. Through evidence-based assessment processes, we help NDIS participants access appropriate funding and develop person-centred behaviour intervention strategies that address the root causes of concerning behaviours.

What is Functional Behaviour Assessment?

Definition and Core Purpose

A functional behaviour assessment involves a comprehensive evaluation process that identifies why challenging behaviours occur, rather than simply focusing on what behaviours look like. This systematic approach examines the function each behaviour serves for the individual, enabling behaviour support practitioners to develop targeted intervention strategies.

Unlike traditional behaviour management approaches that often use restrictive practices, functional behaviour assessment prioritises understanding the individual’s communication attempts through their actions. This person-centred methodology aligns directly with NDIS principles of participant choice and control.

The Science Behind FBA

Evidence-based functional behaviour assessment utilises the ABC model – examining Antecedents (what happens before), Behaviour (the specific action), and Consequences (what occurs after). This systematic data collection approach reveals patterns that help behaviour specialists understand environmental factors, sensory needs, communication difficulties, and other triggers contributing to challenging behaviours.

Research consistently demonstrates that interventions developed from comprehensive functional behaviour assessment prove more effective than generalised behaviour management strategies. The assessment process incorporates multiple data sources, including direct observation, interviews with family carers and support workers, and analysis of historical behaviour patterns.

Functional Behaviour Assessment vs Traditional Behaviour Management

Traditional behaviour management often focuses on reducing challenging behaviours through immediate consequences or restrictive practices. In contrast, functional behaviour assessment takes a proactive, holistic approach that:

• Identifies underlying reasons for behaviour patterns
• Develops positive behaviour support strategies
• Teaches functional communication skills
• Addresses environmental modifications
• Promotes long-term success through sustainable interventions

The FBA Process: A Step-by-Step Guide

Initial Assessment Phase

The functional behaviour assessment process begins with comprehensive information gathering from multiple sources. Behaviour support practitioners collaborate with NDIS participants, family members, support workers, and allied health professionals to understand the individual’s daily routines, preferences, communication methods, and historical behaviour patterns.

During this phase, practitioners examine medical records, previous assessments, and existing support plans to establish baseline understanding of the person’s needs and circumstances.

Data Collection Methods

Systematic data collection forms the foundation of quality functional behaviour assessment. Practitioners employ various evidence-based tools including:

Direct Observation: Behaviour specialists observe individuals in their natural environments – home, community, work, or educational settings – documenting specific behaviour occurrences, duration, intensity, and surrounding circumstances.

Functional Assessment Interviews: Structured interviews with family carers, support workers, and other key people provide insights into behaviour patterns across different settings and situations.

Behaviour Rating Scales: Standardised assessment tools help quantify behaviour frequency and impact on daily functioning.

Analysis and Hypothesis Development

Following comprehensive data collection, behaviour support practitioners analyse patterns to develop hypotheses about behaviour function. Common behaviour functions include:

• Attention seeking from preferred people
• Escape or avoidance of demands or situations
• Access to preferred items, activities, or sensory input
• Communication of needs, wants, or discomfort

This analysis phase enables practitioners to understand individual motivations and develop targeted positive behaviour support strategies.

Timeline and What to Expect

A thorough functional behaviour assessment typically requires 4-6 weeks, depending on behaviour complexity and data collection requirements. NDIS participants and families can expect regular communication throughout the process, with practitioners providing updates on findings and preliminary recommendations.

FBA’s Critical Role in NDIS Planning

NDIS Framework Alignment

Functional behaviour assessment directly supports core NDIS principles by promoting participant choice, control, and independence. The assessment process ensures behaviour support interventions align with individual goals, cultural values, and personal aspirations outlined in NDIS plans.

Funding Justification

Comprehensive functional behaviour assessment provides essential evidence for NDIS funding requests related to behaviour support services. The assessment documentation demonstrates participant needs and justifies inclusion of specific supports such as:

• Behaviour support practitioner services
• Positive behaviour support plan development
• Support worker training and capacity building
• Allied health therapeutic interventions
• Assistive technology for communication or sensory needs

Integration with Support Categories

Core Supports: Functional behaviour assessment findings inform daily support needs, including assistance with social and community participation, consumables, and transport requirements.

Capacity Building: Assessment recommendations guide therapeutic supports, including behaviour intervention training for family carers and support workers.

Capital Supports: FBA may identify needs for home modifications, assistive technology, or vehicle modifications to address environmental triggers.

Quality and Safeguards Commission Requirements

The NDIS Quality and Safeguards Commission mandates functional behaviour assessment before approving comprehensive behaviour support plans involving restrictive practices. This requirement ensures evidence-based decision-making and promotes least restrictive alternatives.

Benefits for NDIS Participants and Families

Immediate Benefits

• Reduced frequency and intensity of challenging behaviours
• Improved safety for participants and support workers
• Enhanced family confidence in managing difficult situations
• Better understanding of individual communication needs

Long-term Outcomes

• Increased community participation and social engagement
• Development of functional communication skills
• Greater independence in daily living activities
• Improved relationships with family, friends, and support workers
• Enhanced quality of life and personal wellbeing

Family and Carer Empowerment

Functional behaviour assessment includes comprehensive training for family carers and support workers, ensuring consistent implementation of positive behaviour support strategies across all environments. This collaborative approach promotes sustainable outcomes and reduces reliance on external behaviour support services over time.

Who Needs a Functional Behaviour Assessment?

Eligibility Criteria

NDIS participants may require functional behaviour assessment when experiencing challenging behaviours that:

• Present safety risks to themselves or others
• Interfere with daily functioning, learning, or community participation
• Require restrictive practices or emergency interventions
• Impact family wellbeing or support worker effectiveness

Specific Conditions and Circumstances

Functional behaviour assessment proves particularly beneficial for individuals with:

• Autism spectrum disorders: Addressing sensory processing issues, communication difficulties, and routine disruptions
• Intellectual disability: Managing transitions, social interactions, and independence skill development
• Acquired brain injury: Responding to cognitive changes, emotional regulation challenges, and environmental adaptations
• Mental health conditions: Integrating behaviour support with therapeutic interventions

Age Considerations

Behaviour support practitioners adapt functional behaviour assessment approaches based on developmental stage, cognitive ability, and communication capacity. Paediatric assessments involve family-centred approaches, while adult assessments emphasise participant choice and self-determination.

Choosing the Right FBA Provider
