Functional Behavior Assessments and Behavior Intervention Plans are the backbone of effective behavior support in schools. When done well, they transform challenging behaviors into opportunities for skill-building and success. When done poorly, they waste time, frustrate everyone, and fail students who desperately need help. The difference between effective and ineffective FBAs/BIPs almost always comes down to methodology. This guide covers the evidence-based practices that separate gold-standard behavioral assessment from well-intentioned guesswork.
The Ethical Imperative for Evidence-Based Practice
Using evidence-based practices isn't just good professional practice—it's an ethical obligation. Students with challenging behaviors deserve interventions that have the highest probability of success, not approaches based on tradition, convenience, or guesswork.
The Cost of Getting It Wrong
When FBAs misidentify function or BIPs use non-function-based interventions, students may experience: increased challenging behavior, unnecessary restrictive interventions, academic regression, damaged relationships with staff, and missed opportunities for skill development. Time spent on ineffective interventions is time the student doesn't get back.
Evidence-Based Practice: What Research Shows
2-3x

80%+
Success rate when FBA correctly identifies function (Hanley et al., 2003)
50%

30%
Typical treatment fidelity rate without monitoring (DiGennaro Reed et al., 2011)
Proper FBA Methodology
A valid FBA is not a form to fill out—it's a systematic process for understanding why behavior occurs. The quality of your intervention depends entirely on the quality of your assessment.
Required Components
1. Record Review
Examine existing documentation before collecting new data:
- Previous FBAs and BIPs
- IEP goals and progress reports
- Discipline records and office referrals
- Medical and developmental history
- Academic assessments
2. Interviews
Gather perspectives from multiple informants:
- Teachers (all relevant settings)
- Paraprofessionals and support staff
- Parents/guardians
- The student (when appropriate)
- Related service providers
3. Direct Observation
Systematic observation across settings and times:
- ABC (Antecedent-Behavior-Consequence) data collection
- Multiple observation periods
- Both problem and non-problem contexts
- Scatter plot analysis for time patterns
4. Data Analysis
Synthesize information to identify patterns:
- Identify consistent antecedent triggers
- Analyze consequence patterns
- Look for setting event correlations
- Formulate testable hypothesis about function
Common FBA Shortcuts to Avoid
- Single-source data: Relying only on teacher report without observation
- Assumed function: Deciding function before collecting data
- Template FBAs: Filling in forms without genuine analysis
- Skipping the student: Not considering the student's perspective
- Ignoring setting events: Missing factors like sleep, medication, home issues
- One observation: Drawing conclusions from a single observation period
Function-Based Intervention Planning
The fundamental principle of behavioral intervention is that interventions must match the function of the behavior. A behavior that serves to escape demands requires different intervention than one that serves to gain attention.
The Four Functions of Behavior
Escape/Avoidance
Behavior occurs to get away from or avoid something aversive.
Examples: Task refusal, elopement during difficult work, aggression when demands are placed
Attention
Behavior occurs to gain social attention from others.
Examples: Calling out, clowning behavior, negative attention-seeking
Tangible/Access
Behavior occurs to gain access to items or activities.
Examples: Tantrums for preferred items, aggression for access to computer
Automatic/Sensory
Behavior produces its own reinforcement independent of social consequences.
Examples: Repetitive motor movements, self-stimulation
Matching Interventions to Function
| Function | Effective Strategies | Contraindicated |
|---|---|---|
| Escape | Task modification, breaks for compliance, teach request for help | Removing demands after behavior (reinforces escape) |
| Attention | Planned ignoring, NCR attention, teach appropriate bids | Lengthy verbal reprimands (provides attention) |
| Tangible | Scheduled access, token economies, teach waiting/requesting | Giving item to stop behavior (reinforces problem behavior) |
| Automatic | Sensory alternatives, environmental enrichment, competing responses | Social consequences (behavior isn't socially maintained) |
The Critical Question
Before implementing any intervention, ask: "Does this strategy address the why behind the behavior, or just the behavior itself?" If you're only addressing topography (what the behavior looks like) without addressing function (why it occurs), the intervention is unlikely to produce lasting change.
Treatment Fidelity: Why It Matters
Treatment fidelity—the degree to which an intervention is implemented as designed—is one of the most critical and most neglected aspects of behavior intervention. An excellent BIP implemented poorly will fail; a good BIP implemented consistently will succeed.
The Fidelity Problem
Research consistently shows that without active monitoring, treatment fidelity in schools averages only 30-50%. This means the majority of BIPs are not being implemented as written—making it impossible to know whether lack of progress reflects a flawed plan or flawed implementation.
Monitoring Fidelity
Fidelity Monitoring Methods
- ✓ Direct observation: Specialist observes implementation and rates fidelity
- ✓ Self-monitoring checklists: Implementers track their own adherence
- ✓ Permanent products: Review of reinforcement logs, data sheets, documentation
- ✓ Video review: Recording and reviewing implementation sessions
When Fidelity Is Low
Low fidelity is a signal that something needs to change. Common causes include:
- Complexity: BIP has too many components to implement consistently
- Training gaps: Implementers don't fully understand procedures
- Resource constraints: Insufficient time, materials, or support
- Buy-in issues: Implementers don't believe in the approach
- Competing demands: Other responsibilities interfere
Before Changing the BIP
When a BIP isn't producing results, always assess fidelity first. Changing the plan when the real problem is inconsistent implementation will only create more confusion and continued failure.
Progress Monitoring Requirements
Effective progress monitoring allows you to detect trends, make timely adjustments, and demonstrate accountability. Without regular data review, you're flying blind.
Frequency Guidelines
| Situation | Minimum Review Frequency |
|---|---|
| New BIP implementation | Weekly for first month |
| High-intensity behaviors | Weekly ongoing |
| Stable, showing progress | Bi-weekly to monthly |
| Not showing expected progress | Weekly with team problem-solving |
Visual Analysis
Graphing behavior data allows for visual trend analysis that's more meaningful than looking at raw numbers:
- Level: Is the overall frequency/intensity changing?
- Trend: Is behavior increasing, decreasing, or stable?
- Variability: How consistent is the data pattern?
- Immediacy: How quickly did change occur after intervention?
When to Modify or Discontinue
Knowing when to adjust a BIP is as important as the initial plan development. Both premature changes and stubborn adherence to failing plans harm students.
Decision Rules
Continue Current Plan When:
- Data shows consistent decreasing trend in problem behavior
- Replacement behavior is increasing
- Fidelity is high and consistent
Modify Plan When:
- No progress after 4-6 weeks with high fidelity
- Partial progress but plateau reached
- New patterns or functions emerge
- Environmental changes affect plan viability
Reconduct FBA When:
- Behavior is worsening despite modifications
- Function hypothesis appears incorrect
- Significant life changes (new placement, trauma, medication)
- New behaviors of concern emerge
Multi-Disciplinary Collaboration
Effective FBA/BIP development requires collaboration across disciplines. Each team member brings unique expertise essential to comprehensive assessment and intervention.
| Team Member | Primary Contributions |
|---|---|
| BCBA/Behavior Specialist | FBA methodology, function identification, intervention design |
| School Psychologist | Assessment, cognitive/emotional factors, mental health considerations |
| Special Education Teacher | Daily implementation, academic integration, data collection |
| General Education Teacher | Inclusive setting perspective, peer dynamics, curriculum demands |
| Parents/Guardians | Home context, history, cultural considerations, carryover |
| Related Service Providers | Communication, motor, sensory factors affecting behavior |
