What is the underlying purpose of the behavior? Why is the student doing it? Although it may seem counterintuitive, the student engages in negative behavior because it consistently works to get a desired outcome. There are four functions of behavior to look for: attention, escape, tangible, and sensory.
Engaging in challenging behaviors often gets students consistent attention. Keep in mind that all attention is good attention! If the student receives negative attention, such as a reprimand, after engaging in the behavior, this is still attention. Attention can take many forms, such as looking, laughing, talking, and helping, and can be received from anyone, including peers, teachers, and administrators.
Do behaviors occur because the student wants an adult to reprimand them, a peer to laugh, an admin to come into the room? Do they stop when provided attention?
When a student’s behavior is driven by the need for attention, any response—positive or negative—can reinforce it. Even a reprimand, a lecture, a peer’s laughter, or an administrator stepping in can meet that need. If the behavior tends to stop once attention is given, that’s a strong clue that attention is the function, and we may need to shift our focus to providing more positive, proactive attention instead.
Engaging in challenging behavior at school, can often lead to getting out of doing work or participating in a non-preferred activity. If the next class includes non-preferred work, the student may engage in the behavior during the transition in order to avoid going to the class altogether.
Do behaviors often occur to avoid work/in the presence of task demands? Do behaviors stop when demands are removed?
When behavior is driven by escape, it often happens right before or during non-preferred tasks, like difficult work or transitions. If the behavior stops once the demand is removed, it's a strong sign the student is trying to avoid something. Understanding this helps us plan supports that make tasks more manageable instead of reinforcing the avoidance.
Challenging behavior can also lead to gaining or maintaining access to a favorite item or desired activity.
Do behaviors occur when items are removed or when the student is told “no”? Do behaviors occur to get preferred items/activities? Do they stop when given items?
When behavior is tied to a tangible function, it often happens when a preferred item or activity is denied or removed. If the behavior stops once the student gains access, it suggests they’re using the behavior to get what they want. Recognizing this helps us teach more appropriate ways to request items and set clear, consistent boundaries around access.
Sometimes challenging behavior just feels good internally. The student may engage in running, flopping, spinning, or rocking simply because it is an enjoyable sensory experience.
Do the behaviors occur to meet a sensory need (sight, touch, smell, hearing, taste)? Do behaviors appear to occur regardless of a trigger (antecedent)?
When behavior serves a sensory function, it often happens because the action itself feels good or helps the student self-regulate. These behaviors—like spinning, flopping, or tapping—can occur even without a clear trigger. If the student seems unaware of others or continues regardless of consequences, they may be meeting a sensory need, which means we should consider supportive strategies rather than punishment.
