When supporting students with challenging behaviors, clear and consistent language matters. Whether you’re an educator writing a behavior report or a caregiver preparing for an IEP meeting, using defined behavior categories, describing the topography (what it looks like), and identifying the severity helps teams understand the behavior clearly and plan appropriate supports.
This post outlines the three key components of behavior description:
- Behavior categories (types),
- Behavior topography (observable form),
- Behavior severity (impact and intensity).
1. Behavior Categories: Grouping by Function or Type
Behavior categories help identify what kind of behavior occurred. These terms are especially useful for data collection, communication between teams, and developing Functional Behavior Assessments (FBAs).
Common categories include:
- Tantrum: Crying, yelling, flailing, or dropping to the floor following a demand or denied access
- Self-Injury: Hitting, biting, or scratching oneself; banging head
- Aggression (Physical): Hitting, kicking, pushing, or throwing with intent to harm
- Aggression (Verbal): Yelling, cursing, name-calling, threats
- Property Destruction: Breaking objects, tearing materials, knocking over furniture
- Elopement: Leaving a supervised area without permission
- Protest/Refusal: Turning away, saying “no,” pushing materials away when prompted
- Stereotypy (Vocal, Motor, Sensory): Repetitive sounds, movements, or sensory behaviors
- Disruption: Noisy, non-harmful behaviors that interrupt instruction (e.g., tapping, yelling)
- Mouthing: Putting non-food items in the mouth
- Inappropriate Toileting: Urinating or defecating outside of appropriate settings
- Sexual Behavior: Sexual gestures or contact in inappropriate settings
2. Behavior Topography: What the Behavior Looks Like
Topography refers to the form of the behavior—how it physically presents. This is essential for creating accurate definitions during data collection.
Examples:
- Tantrum topography: Loud crying, rolling on the ground, screaming
- Self-Injury topography: Biting hand, slapping face, head banging
- Verbal aggression topography: Shouting “I hate you,” using curse words, threatening statements
- Property destruction topography: Throwing a chair, ripping books, kicking a wall
Use objective, observable language—avoid labeling or guessing the child’s intent. For example, say “threw binder across room” instead of “being disrespectful.”
3. Behavior Severity: Understanding the Impact
Severity levels help teams assess how serious the behavior is and determine what kind of response or documentation is required. The Behavior Data Packet outlines severity levels as:
Low
- Mild or brief behavior with minimal impact
- Examples: Whining, tapping, light mouthing
Moderate
- Noticeable behavior that interrupts learning or social engagement
- Examples: Loud crying, slapping, repetitive disruptive sounds
High (Requires Incident Report)
- Behavior that causes property damage, injury, or emotional distress
- Examples: Punching, head-banging, breaking classroom items
Severe (Requires Behavior Emergency Report)
- Dangerous, life-threatening, or crisis-level behavior
- Examples: Eye gouging, sexual assault, running into traffic
Example Matrix: Tantrum
| Severity | Description |
|---|---|
| Low | Mild whining, quick recovery |
| Moderate | Loud crying, some flailing, lasts under 10 minutes |
| High | Screaming, property destruction |
| Severe | Thrashing, physical aggression, injury to self/others |
Use this type of matrix across all observed behaviors to document trends, guide intervention intensity, and support crisis planning.
Why This Matters
Understanding and documenting behavior using categories, topography, and severity:
- Ensures consistency across team members,
- Provides clarity for IEP and medical teams,
- Protects student dignity by focusing on observable data—not assumptions,
- Supports legal compliance for documentation (e.g., incident reports, FBAs),
- Helps teams respond appropriately based on risk level.
