Domain 2: Behavioral Supports
The behavioral, emotional, and social-regulation supports a student needs to access instruction and participate safely. Boundaries first — built for when you have a student in front of you, rating this one domain.
What this domain covers
The specially designed instruction (SDI) and supports a student needs for behavioral, emotional, and social regulation — so they can access instruction, participate safely, and engage in school routines. It reflects the intensity and structure of behavior intervention, not the mere presence of disability-related behavior.
That distinction matters: a student "having behaviors" is not what's rated. What's rated is the planned intervention the IEP requires. glossary
Academic instruction → Domain 1. Communication systems → Domain 3. Executive function/independence, unless behavior-driven → Domain 4. Personal care/health → Domain 5.
The four factors, in this domain
Rate each 0–3; the domain takes the highest.
- A — How much behavioral SDI: amount/frequency/intensity.
- B — Who delivers it: required behavioral credentials.
- C — Ratio: required reduced ratio for behavior.
- D — Equipment: required behavioral technology.
The decision boundaries
Factor A — how much behavioral instruction. The Behavior-specific hinge is preventive vs. crisis:
| Level | Boundary |
|---|---|
| 1 | Targeted, isolated support; <60 min/week; at least one behavior goal |
| 2 | Regular, preventive programming; consistently implemented BIP; multiple goals |
| 3 | Daily/near-continuous; reactive, safety-driven, or crisis-oriented — de-escalation, emergency response |
A student with lots of preventive behavior service is still a 2. The move to 3 is when crisis response enters the picture.
Factor B — who delivers. Typically-qualified staff with routine training (1) → behavior specialist, counselor, social worker, school psychologist with targeted competencies + coaching (2) → highly specialized expertise for crisis-level, function-based intervention with frequent plan redesign (3).
Factor C — ratio. Intermittent, responsive support (1) → planned reduced ratio at known high-risk times/transitions (2) → near-continuous ratio for safety and immediate response (3).
Factor D — equipment. Visual schedules, choice boards, noise-canceling headphones (1) → self-monitoring apps, routine calming/sensory tools (2) → systems foundational to regulation/safety; sometimes AAC required to prevent escalation (3).
The domain score
Highest factor wins. A student whose behavior service is moderate (A=2) but who requires crisis-trained staff (B=3) scores the domain 3. How scores become a tier
Traps specific to this domain
- Preventive ≠ significant. A well-run BIP with regular service is a 2, not a 3, unless there's reactive/crisis-level support. Don't inflate to 3 because the BIP is detailed.
- A BIP existing isn't automatically Level 3 on Factor A. Level 2 explicitly includes a consistently implemented BIP. Look at intensity and whether crisis response is required.
- Behavior that's really a communication or sensory need belongs in the driving domain. Rate here only if behavior intervention is the primary support. what is a domain
- Ages 3–5: much behavior is developmentally typical; significant ratings hinge on frequency, severity, and impact on access and safety — not on age-expected behavior.
