Writing a behavior goal from an FBA

By the IEP Atlas editorial teamLast updated November 1, 2026

Short answer

To write a behavior goal from an FBA, start from the hypothesis. The antecedent becomes the goal's condition, the function tells you the replacement skill, and the FBA data give the baseline. Write the goal for the replacement skill in the same unit as the baseline, set the criterion from that baseline, and track the problem behavior alongside it.

An FBA produces a sentence: when this happens, the student does this, to get or avoid that. A behavior goal should be built straight from that sentence. When it is, every part of the goal has a source, and the goal will measure whether the plan is meeting the need that drives the behavior.

Many behavior goals are written as if the FBA never happened: "will reduce aggressive behavior" or "will follow classroom rules." This guide shows how to get from the hypothesis to a goal that matches it, with one case worked from start to finish. For the full assessment process, see how to conduct an FBA; for the plan itself, see the FBA and BIP guide.

What you need before you start

The FBA hypothesis statement, with the setting event, antecedent, behavior and function.
The operational definition of the problem behavior.
Baseline counts of the problem behavior.
The replacement behavior the team chose for the BIP.
3 to 5 days to take a baseline on the replacement behavior, if nobody has yet.

How the hypothesis maps onto the goal

Hypothesis part	Goal part	Example
Antecedent	Condition	"When told computer time is over"
Function	Which replacement skill to teach	Item access, so: ask for more time or a later turn
Behavior	What the goal replaces, tracked as supporting data	Hitting the adult or the screen
FBA data	Baseline	0 of 9 transitions with a request; 4 hits per week
Plan length and growth expected	Criterion and timeline	8 of 10 transitions across 3 weeks

Step by step

Step 1: Restate the hypothesis in one line

Write it at the top of your notes. If you cannot state one function, the FBA is not finished. The behavior hypothesis statement examples show 24 complete ones.

Step 2: Choose the replacement skill

The replacement must get the same result as the problem behavior, and get it as fast. Escape points to asking for a break or help. Attention points to a signal for adult or peer contact. Item access points to asking, waiting or accepting "later." Sensory points to a matched input. The replacement behavior examples by function have 24 options.

Step 3: Turn the antecedent into the condition

The goal's condition should name the situation the FBA found. "During independent writing tasks of more than one paragraph" is tied to the data. "Throughout the school day" is not, and it makes the goal hard to measure because the chances to use the skill are everywhere.

Step 4: Take a baseline in the goal's unit

The problem behavior baseline is usually a count. The replacement goal usually needs opportunity data: the number of times the student used the skill out of the times the antecedent happened. Collect 3 to 5 days, and report the median. How to collect baseline data covers the details.

Step 5: Set the criterion from the baseline

Pick a level that shows real change and is reachable within the IEP year, often with a stretch target for the first progress report. A baseline of 0 of 9 can reach 8 of 10 with direct teaching. Add a durability piece such as "across 3 consecutive weeks," so one good day does not count as mastery.

Step 6: Name the measurement method

Say how the data will be taken and how often: "measured by opportunity data during computer transitions, recorded daily." The IEP must describe how progress will be measured.^[1]

Step 7: Track the problem behavior alongside

Write the problem behavior count into the BIP or as a second measure on the goal. If the replacement rises and the problem behavior does not fall, the team needs to know.

Step 8: Check the goal

Read it against the hypothesis. Does the condition match the antecedent? Does the skill serve the function? Is the unit the same as the baseline? Then paste it into the goal checker.

Worked example: Kevin, grade 2

The student and numbers are fictional.

FBA hypothesis. When an adult tells Kevin that computer time is over, especially in the afternoon, he hits the adult or the screen to keep using the computer. In 9 of 11 recorded episodes, the adult gave him more time after he hit.

Problem behavior baseline. Hitting during computer transitions: a median of 4 per week over 3 weeks (range 3 to 6).

Replacement skill. Item access, so Kevin will ask for "2 more minutes" using words or a card, then transition when the timer ends. The BIP honors the request every time for the first 3 weeks, then sometimes says "not today, but you can have the first turn tomorrow."

Replacement baseline. Over 5 school days, 9 computer transitions happened. Kevin asked for more time with words 0 times. Baseline: 0 of 9.

Draft goal. "When told computer time is over, Kevin will ask for 2 more minutes using words or his card, then move to the next activity when the timer ends, in 8 of 10 transitions across 3 consecutive weeks, measured by daily opportunity data."

Supporting measure in the BIP. Hitting during computer transitions reduced from a median of 4 per week to 0 or 1 per week.

Objectives.

With a verbal model ("say, 2 more minutes"), Kevin will ask in 8 of 10 transitions.
With the card placed in view and no verbal model, Kevin will ask in 8 of 10 transitions.
Kevin will accept "not today" and transition within 1 minute in 4 of 5 transitions where more time is not given.

Results at the first progress report (fictional). After 9 weeks, Kevin asked for more time in 17 of 20 transitions over the last 2 weeks, and hitting dropped to a median of 1 per week. He had met objective 2 and started work on objective 3.

Common mistakes

Goal ignores the function. Weak: "Kevin will keep his hands to himself 90% of the day." Better: "When told computer time is over, Kevin will ask for 2 more minutes using words or his card..." The skill gets him what hitting got him.

Condition does not match the antecedent. Weak: "Throughout the school day, Kevin will..." Better: "When told computer time is over..." taken from the hypothesis.

Baseline and goal use different units. Weak: baseline "hits 4 times a week"; goal "will request more time 80% of the time." Better: baseline both behaviors: 4 hits per week and 0 of 9 requests. The goal targets the requests; the hits are tracked alongside.

Criterion copied from habit. Weak: "80% accuracy" for a behavior that has no accuracy. Better: "8 of 10 transitions across 3 consecutive weeks," with a denominator that matches the opportunities.

Only a reduction goal. Weak: "Kevin will reduce hitting to 0 per week." Better: a skill goal for the request, with the hitting count as supporting data.

Templates and tools

The replacement behavior goal templates have goal wording by grade band, and the classroom expectations goals cover the longer-term desired behavior.
The FBA template shows where the hypothesis and baseline appear in the report.
Track the replacement on the opportunity data sheet and the problem behavior on the frequency data sheet.
More goal wording is on the behavior IEP goals hub and in behavior goals without compliance.

When behavior impedes a student's learning, the IEP team must consider positive behavioral interventions and supports.^[2] The IRIS Center FBA module walks through linking the hypothesis to the behavior plan and its goals.^[3]

Frequently asked questions

Should a behavior goal target the problem behavior or the replacement behavior?

Write the goal for the replacement behavior, the skill the student will use instead. Track the problem behavior as a second measure. A goal that only says what to stop leaves the student without a way to meet the need behind the behavior.

How do I set a criterion when the baseline is zero?

A zero baseline usually means the skill has not been taught yet. Set a first objective with prompting, then a final criterion such as 8 of 10 opportunities across 3 weeks. Check the data at 6 weeks and adjust if the student is moving faster or slower.

Can one FBA lead to more than one goal?

Yes. If the FBA found different functions in different settings, write one replacement goal for each. Keep the total small, usually one or two behavior goals, so the plan stays manageable for staff.
