PBS...

PBS (Positive Behaviour Support) is a proactive, evidence-based framework designed to improve quality of life by promoting positive behaviours and reducing challenging ones. Rather than reacting to problems after they occur, it focuses on understanding the reasons behind behaviour and putting supports in place to prevent difficulties before they arise.

It is primarily used in schools and community settings, but it can also be effectively applied in homes and clinical environments. PBS involves creating supportive environments, teaching new skills, and reinforcing positive behaviours so individuals can succeed in everyday situations.

Although PBS is related to Applied Behaviour Analysis (ABA), it places a stronger emphasis on prevention, person-centred approaches, and the use of positive reinforcement, rather than relying on reactive or punitive strategies.

Positive Behaviour Supports (PBS)

What is PBS?

  • Positive Behaviour Supports (PBS) is a proactive, evidence-based approach to improving behaviour and quality of life.

  • Focuses on teaching appropriate behaviours rather than punishing negative ones.

  • Commonly used in schools, homes, and community settings.

  • Based on principles of Applied Behaviour Analysis (ABA).

Key Principles of PBS

  • Prevention-focused: Identifies triggers and modifies environments to reduce problem behaviours.

  • Skill-building: Teaches replacement behaviours that serve the same function as challenging behaviours.

  • Positive reinforcement: Encourages desired behaviours through rewards and praise.

  • Individualised support: Strategies are tailored to the individual's needs and strengths.

  • Data-driven: Uses observation and data to guide decisions and measure progress.

Core Components of PBS

  • Functional Behaviour Assessment (FBA)

    • Identifies why a behaviour occurs (attention, escape, sensory, etc.).

  • Behaviour Intervention Plan (BIP)

    • Outlines specific strategies to support positive behaviour.

  • Environmental supports

    • Adjusting routines, expectations, or physical spaces to promote success.

  • Teaching strategies

    • Explicit instruction of social, communication, and self-regulation skills.

Benefits of PBS

  • Reduces challenging or disruptive behaviours.

  • Increases independence and social skills.

  • Improves communication and emotional regulation.

  • Promotes consistency across settings (school, home, community).

  • Builds long-term positive outcomes rather than short-term compliance.

Examples of PBS Strategies

  • Visual schedules and clear routines

  • Positive praise and reward systems

  • Choice-making opportunities

  • Social stories and modeling

  • Calm-down strategies and self-regulation tools


  • Tier 1 (Universal):  Whole-group strategies for all individuals, like clear expectations, routines and rewards (e.g. praise, token systems) to promote a positive culture.
  • Tier 2 (Targeted):  Small-group or individualised supports for those at risk of challenging behaviours, such as social skills training or check-in/check-out systems. 
  • Tier 3 (Intensive):  Highly individualised interventions, often involving (FBAs) Functional Behaviour Assessments and tailored plans for individuals significantly challenged.


The Three-Tier Framework

  • A proactive, structured approach to promoting positive behaviour
  • Teaching clear behavioural expectations (e.g. what respectful behaviour looks like)
  • Reinforcing positive behaviour through praise, encouragement, and rewards
  • Modifying environments to reduce triggers and prevent difficulties
  • Working collaboratively with families and staff to ensure consistent support
  • Focused on prevention, positive reinforcement, and teamwork
