A student's behavior is getting attention in the hallway, the lunchroom, and at the next staff meeting. Someone says, "We need an FBA." Someone else says, "We need to try some things first." Both can be right. The question is what the rule requires, and what the evidence in front of you calls for.

This guide separates the two, then gives a short checklist for the second.

Where IDEA requires an FBA

Situations in which IDEA names an FBA (34 CFR 300.530)
SituationWhat the rule says
A child with a disability is removed from the current placementUnder (d)(1)(ii), the child should receive, as appropriate, a functional behavioral assessment and behavioral intervention services designed to address the behavior violation so it does not recur
The manifestation determination finds the conduct was a manifestation of the disabilityUnder (f)(1), the IEP team must either conduct an FBA, unless one was conducted before the behavior occurred, and implement a behavioral intervention plan, or, if a plan already exists, review it and modify it as necessary

Colorado's guide summarizes the same two situations: after a manifestation finding, the team must complete an FBA, unless one was completed before the at-issue behavior, and implement a BIP, or review and modify an existing one. After a non-manifestation finding, the team must provide, as appropriate, an FBA and behavior interventions designed to address the behavior so it does not occur again. For the review itself, see manifestation determination basics.

Where IDEA asks teams to consider supports

Outside the discipline rules, the standard is softer. Section 300.324(a)(2)(i) says that in the case of a child whose behavior impedes the child's learning or that of others, the IEP team must consider the use of positive behavioral interventions and supports, and other strategies, to address that behavior. "Consider" is the verb. An FBA is one tool the team may choose. Colorado's guide says the supports may include an FBA and a BIP, and must be used proactively where the team determines they would be appropriate.

Checks before an FBA

Queensland's guide offers a sensible order. Before investing time in an FBA, it says, check that universal and classroom supports are in place, because if several students are struggling, the first move is to support the whole class.

Conditions to check first (Queensland guide)
CheckThe questionIf the answer is no
Academic skillsIs most of the class reaching academic benchmarks?Look at instruction first
ExpectationsIs most of the class following the rules, with instructional time protected?Strengthen routines and expectations
ResponsesAre teacher responses to problem behavior consistent and respectful?Fix the response pattern
PersistenceDo the behaviors continue once those conditions are met?Then conduct an FBA

That order does not delay help for a student in crisis. It is a way to avoid assessing a student for a problem that the room creates.

Signs a behavior needs more attention

The IES practice guide on classroom behavior lists behavior that warrants immediate and additional attention. It does so if the behavior persists, escalates, or spreads to other students; lessens the student's or other students' ability to engage in learning; detracts from a positive classroom climate; deviates significantly from the developmentally appropriate behavior of other students; causes others to avoid interacting with the student; or threatens the safety of students or the teacher. The same guide says that brief misbehavior that does not seriously interfere with learning, such as short daydreaming or talking during transitions, can be handled without interrupting instruction.

A quick decision path

  1. Is anyone at risk right now? Follow your safety procedures, and start the assessment process alongside them.
  2. Is a discipline removal involved? If so, the discipline rules in 300.530 apply. Talk to your special education director.
  3. Does the behavior get in the way of the student's learning or others'? If yes, the IEP team must consider positive behavioral supports.
  4. Have the basic supports been tried and the behavior persists? Start gathering data. See baseline before a behavior plan.
  5. Is the cause unclear? An FBA is the tool for working out function. See FBA steps in order.

What a team can do this week

You do not have to wait for a formal assessment to start writing things down. The IES guide recommends simple observation: record occurrences over a few days to a week, noting time of day, setting, and activity, until patterns emerge. That record helps the team decide whether a full FBA is needed, and it saves time if one is.

Recording the decision

Whichever way the team goes, write the decision and the reason on one page, with a date. That record helps the next person who picks up the file and protects the student from a gap in follow-up.

Bringing the family in early

Colorado's guide says parents and guardians are required to be notified and involved throughout the FBA and BIP processes, and that written permission is needed before an FBA used to evaluate a child's needs. Even before a formal step, a call home helps. Families can tell you whether the behavior shows up at home, what happened this morning, and what has worked in the past. That information often decides whether a short data check is enough or a full assessment is called for.

If a parent asks for an FBA, treat the request as information. Ask what they are seeing and what they hope for. Then take it to the team, follow your district's process for requests, and give the parent a date by which they will hear back. A clear answer, even a slow one, builds more trust than a vague promise.

Slips

  • Waiting for a crisis. The rule's softer standard is a reason to act early, not to wait.
  • Starting an FBA with no baseline. A rough count in the first week makes the rest easier.
  • Treating "consider" as "skip." If the team considers positive supports and decides against an FBA, write down why.
  • Assessing the student for what the room does. Use the checks above.

Local rules

Illinois's guidance notes that its state statute requires district policies to include criteria for when a student with a disability may require a behavioral intervention plan. Other states differ, and your district may have criteria of its own. Ask for them. Terms are in the glossary.
