Antecedent
Last updated
An antecedent is what happens right before a behavior, such as a direction, a transition or a hard task, that can trigger it.
Topic: Behavior and FBA/BIP
In plain terms
Antecedents are the A in ABC data. They can be immediate, like being told to put away a tablet, or more distant setting events, like a poor night's sleep, hunger or a change in routine, that make a behavior more likely. Spotting antecedents shows when to prevent problems and when to teach.
How it shows up in an IEP
Antecedent strategies are often the fastest way to reduce problem behavior: warnings before transitions, choices, shorter tasks, or visual schedules. They belong in the BIP, and goal conditions may describe them.
Example
ABC data shows a student's outbursts follow unexpected schedule changes. The team adds a 5-minute warning and a picture of the new activity before each change.
