12.3 Behavior Intervention Plans & Evaluating Effects
Key Takeaways
- A Behavior Intervention Plan (BIP) must be built directly from the FBA's hypothesized function, not from a generic menu of consequences unrelated to why the behavior occurs
- Effective BIPs include prevention/antecedent strategies, explicit teaching of a function-matched replacement behavior, and consequence strategies that reinforce the replacement behavior while withholding reinforcement for the problem behavior
- Consequence strategies should be matched to function: attention-maintained behavior often needs planned attention for appropriate behavior paired with reduced attention for the problem behavior, while escape-maintained behavior often needs task modification plus reinforced appropriate escape requests
- Evaluating a BIP's effects requires comparing intervention-phase data to baseline using level, trend, and variability, combined with a treatment fidelity check before deciding the plan itself needs revision
- A BIP is a living document reviewed and revised using data decision rules; legal requirements for reviewing or revising a BIP after a disciplinary removal are addressed in the PBIS legal-framework chapter and are not repeated here
12.3 Behavior Intervention Plans & Evaluating Effects
Quick Answer: A Behavior Intervention Plan (BIP) translates the FBA's hypothesized function into a concrete, written plan built from three core components: prevention/antecedent strategies that reduce triggers, explicit instruction in a replacement behavior that produces the same payoff as the problem behavior, and consequence strategies matched to that function. Once implemented, the plan is not "finished" — teams continuously collect data and apply decision rules (comparing baseline to intervention-phase level, trend, and variability, after confirming fidelity) to decide whether to continue, adjust, or fade the plan. This section focuses on plan design and data-based evaluation; legal review requirements tied to disciplinary removals are covered separately in the PBIS legal-framework chapter and are only briefly cross-referenced here.
Why the BIP Must Follow From the FBA
A BIP that is not clearly connected to the FBA's hypothesized function is little more than a generic list of consequences — and generic consequences frequently backfire. Sending a student to the office for attention-maintained behavior can increase the behavior by supplying the very attention that maintains it; requiring extra practice work as a "consequence" for escape-maintained behavior can increase avoidance by making the aversive task even larger. Every strategy chosen for a BIP should be traceable back to a specific line in the FBA: this antecedent triggers the behavior, this consequence maintains it, therefore this plan changes the antecedent and offers an equally effective — but appropriate — way to reach that same consequence.
Component One: Prevention / Antecedent Strategies
Prevention strategies change the environment before the behavior has a chance to occur, reducing the likelihood of the antecedent triggering the problem behavior at all.
| Antecedent Identified in FBA | Example Prevention Strategy |
|---|---|
| Difficult or lengthy academic task | Break the task into smaller chunks; pre-teach vocabulary; offer choice of task order |
| Unstructured transitions | Provide a visual schedule and a countdown warning before transitions |
| Non-preferred activity assigned without warning | Give advance notice and a clear, predictable routine for activity changes |
| Crowded or loud settings | Adjust seating, provide noise-reducing supports, or offer a quieter alternative space |
| Denied access to a preferred item | Build in scheduled access or a clear, taught way to request the item |
Prevention strategies are often the highest-leverage part of a BIP because they reduce the number of opportunities for the problem behavior to occur — a student who is never placed in the triggering situation has far fewer chances to practice the problem behavior.
Component Two: Teaching the Replacement Behavior
Every BIP must directly and explicitly teach an acceptable replacement behavior that (a) is functionally equivalent to the problem behavior (it produces the same type of consequence) and (b) is at least as efficient for the student to perform. If raising a hand to ask for a break takes longer to get a response than pushing materials off the desk, the student has little incentive to switch. Replacement behaviors are taught the same way any new skill is taught: model it, prompt it, provide many practice opportunities in the actual triggering context, and reinforce it heavily and immediately in the early stages before gradually thinning reinforcement.
Component Three: Function-Matched Consequence Strategies
Consequence strategies have two jobs: reinforce the replacement behavior, and reduce or eliminate reinforcement for the problem behavior — both must be matched to the function identified in the FBA.
| Hypothesized Function | Reinforce the Replacement Behavior By... | Reduce Reinforcement for Problem Behavior By... |
|---|---|---|
| Attention | Providing frequent, immediate, genuine attention when the student uses the appropriate attention-seeking behavior (e.g., a taught hand signal) | Delivering brief, neutral, low-attention responses to the problem behavior rather than long verbal reprimands |
| Escape/Avoidance | Honoring a taught "break" request quickly and consistently; adjusting task demands proactively | Not allowing the problem behavior itself to produce escape (e.g., continuing to expect task completion, with support, rather than removing the task) |
| Access to Tangibles/Activities | Teaching and reinforcing an appropriate request (e.g., waiting, asking, trading) that reliably earns the item | Ensuring the problem behavior does not result in obtaining the item or activity |
| Sensory/Automatic | Providing an appropriate sensory outlet or replacement activity that offers similar sensory input | Reducing opportunity/access for the sensory behavior when safe and appropriate, often paired with an alternative sensory activity |
Because withholding the usual payoff for a problem behavior can temporarily increase that behavior before it decreases (an extinction burst), teams should plan for this possibility, ensure safety, and communicate it to all adults implementing the plan so a burst is not mistaken for plan failure.
Progress Monitoring and Data Decision Rules
A BIP is only as good as the data used to evaluate it. Teams should specify, in the plan itself, exactly what data will be collected (using the measurement systems from Section 12.1 that match the target behavior's dimension), how often, and by whom. Evaluating whether the plan is "working" then follows the same visual-analysis logic used for any behavioral data:
- Compare intervention-phase data to baseline — is the level of problem behavior lower, and is the replacement behavior increasing?
- Look at trend, not single days — a consistent downward trend in problem behavior (or upward trend in replacement behavior use) across multiple consecutive sessions supports continuing the plan
- Check treatment fidelity first — before concluding a plan has failed, confirm the plan was implemented as written; inconsistent implementation, not a flawed hypothesis, is a common cause of poor data
- Set a pre-planned decision point — many teams specify in advance (e.g., "if no improvement after 2 weeks of consistent implementation, the team will reconvene to revise the hypothesis or strategies") rather than waiting indefinitely
- Fade supports as behavior stabilizes — once the replacement behavior is well established and problem behavior is consistently low, teams gradually thin reinforcement schedules and prevention supports rather than removing them abruptly
A Living Document, Not a One-Time Product
A BIP is reviewed and revised whenever data shows it is not working, when the student's needs or environment change, or on a regular team-determined schedule. Certain disciplinary events — most notably a removal that triggers a manifestation determination review — carry their own legal requirements about when a BIP must be reviewed or created; those legal triggers and procedures are addressed in the PBIS legal-framework chapter and are not repeated here. For the FTCE exam, the key distinction to hold onto is that BIP design comes from the FBA's function, while BIP evaluation comes from ongoing data decision rules — two related but separate skills the Competency 4 blueprint expects candidates to demonstrate.
An FBA determines that a student's disruptive calling-out behavior is maintained by escape from difficult writing tasks. Which consequence strategy is most directly matched to this function?
After two weeks of a new BIP, a student's target behavior data shows no improvement. Before concluding the plan's hypothesized function is wrong, the team should first check:
Shortly after a plan withholds the usual attention payoff for a student's problem behavior, the behavior briefly increases in frequency and intensity before it begins to decrease. What does this pattern most likely represent?
