Question 1

What is the ABC model in behaviour tracking?

Accepted Answer

The ABC model (Antecedent, Behaviour, Consequence) is the foundational framework used in Applied Behaviour Analysis (ABA) and Positive Behaviour Interventions and Supports (PBIS) to understand why a specific behaviour occurs and what maintains it. The Antecedent is what happened immediately before the behaviour: the instruction given, the transition occurring, the social interaction that preceded it, or the environmental condition present. The Behaviour is the specific, observable, measurable action, not a label like 'disruptive' but a description like 'called out four times during direct instruction without raising hand.' The Consequence is what happened immediately after the behaviour: the teacher response, peer reaction, or change in task demand. The ABC model is powerful because it reveals patterns: if a student's disruptive behaviour consistently occurs during independent writing tasks, the antecedent suggests the behaviour may be avoidance of a difficult task rather than attention-seeking, which leads to a completely different intervention.

Question 2

What is PBIS and how does behaviour tracking support it?

Accepted Answer

Positive Behavioural Interventions and Supports (PBIS) is a multi-tiered framework for improving school climate by explicitly teaching and reinforcing expected behaviours, using data to identify students who need additional support, and applying evidence-based interventions at increasing levels of intensity. Tier 1 PBIS applies to all students, universal positive behaviour expectations taught school-wide. Tier 2 applies to the 10-15% of students who need more structured support despite Tier 1. Tier 3 applies to the 5% of students with the most intensive, individualised needs. Behaviour data collection is central to all three tiers. Without systematic tracking, schools cannot identify which students have crossed the threshold from Tier 1 to needing Tier 2 support, cannot measure whether interventions are working, and cannot justify referrals for Functional Behaviour Assessments. Consistent ABC data over two to four weeks is typically what a behaviour specialist needs to begin a Tier 3 assessment.

Question 3

What is a Functional Behaviour Assessment and when is it needed?

Accepted Answer

A Functional Behaviour Assessment (FBA) is a structured process used by a team (typically including the classroom teacher, a school psychologist or behaviour specialist, and a parent) to identify the function of a student's persistent challenging behaviour. The FBA uses systematic observation, interview data, and behaviour tracking records to determine why the student is engaging in the behaviour: to access something desirable (attention, tangibles, sensory stimulation) or to escape or avoid something aversive (difficult tasks, social demands, sensory discomfort). The FBA is required under IDEA for students with disabilities whose behaviour significantly impedes their learning or the learning of others, particularly before changing the placement or significantly modifying the IEP. Classroom behaviour tracking data is a primary input to the FBA, a teacher who has logged 20 ABC entries over four weeks can identify patterns that a one-hour observation session would miss.

Question 4

Should I track positive behaviours as well as concerns?

Accepted Answer

Yes (tracking only problematic behaviour produces a skewed picture of a student and can reinforce a deficit-focused narrative. A complete behaviour record documents both concern entries and positive entries: on-task behaviour during challenging tasks, prosocial interactions, self-regulation after a difficult moment, and academic persistence. This is particularly important for students who have a history of negative behaviour records, because positive entries provide evidence of growth and capability that is useful in IEP meetings, parent conferences, and referral processes. Some PBIS frameworks recommend that teachers aim for a 4:1 ratio of positive-to-corrective interactions with students who are at risk, and a behaviour log that reflects this ratio demonstrates that the teacher is implementing the framework with fidelity. A log showing only concerns) even if accurate, is less defensible if a parent questions whether the teacher tried positive strategies.

Question 5

How many behaviour entries do I need before requesting additional support?

Accepted Answer

There is no universal threshold, but most Tier 2 screening processes use frequency, intensity, and duration as criteria. A common rule of thumb for Tier 2 referral is three or more office discipline referrals in a semester, or teacher-documented concern entries on six or more school days over a four-week period that have not responded to Tier 1 strategies. For Tier 3 and FBA referrals, most school psychologists want to see two to four weeks of consistent ABC data collected across multiple settings and times of day. Quality matters more than quantity, ten well-documented ABC entries that clearly describe the antecedent conditions, the specific behaviour, and the consequence are more useful than thirty vague entries. The documentation in this tool creates a paper trail that protects both the student's rights and the teacher's professional judgment if a behaviour escalates or a parent disputes the teacher's characterisation of their child.
