Writing Objective Session Notes and Communicating With Your Team

A session note is a written record that lets someone who wasn't there understand what happened. Your supervisor uses your notes and data to make decisions about a client's program. So the most useful note describes what anyone in the room could have seen or heard. It does not record what you think it meant.

This lesson also covers what to do with information you can't act on yourself: a caregiver's worry, a health report, data that looks wrong, or a safety concern.

By the end of this lesson, you should be able to:

• Tell an observation apart from an interpretation, and rewrite an interpretation as an objective observation.
• Write a session note that records behavior, context, procedure and the client's response.
• Record illness, medication and schedule information as observations or attributed reports, without diagnosing or advising, and pass it on without delay.
• Decide whether a concern goes to your supervisor routinely, goes to them promptly, or needs urgent safety action first.
• Correct a record honestly and share client information only when necessary.

Before you start: You don't need prior behavior-analysis training. A supervisor here means the qualified person responsible for overseeing your work and directing the client's services.

Observation versus interpretation

An objective statement describes what happened in a way another observer could confirm. In plain terms, it records what you saw or heard, not what you concluded. A subjective statement adds your judgment about feelings, motives or causes.

Interpretations aren't always wrong. The problem is that they hide the evidence. Your supervisor can't check a conclusion if the note never says what led to it.

Contrast 1

• Subjective: "Jordan was frustrated and didn't want to work."
• Objective: "During the matching task, Jordan pushed the cards off the table 3 times and said 'no more' twice."

The second version lets your supervisor see the actual behavior and how often it happened. "Frustrated" might be right. It might also be tiredness, boredom or a task that's too hard. The objective note leaves that question open for the person responsible for answering it.

A quick test: could a second observer, watching the same moment, agree with your sentence without sharing your opinion? If not, describe the action instead.

What a useful note contains

A strong note connects four things:

• Behavior: what the client did, in observable terms.
• Context: when and where it happened, and what was going on just before.
• Procedure: what you did, following the plan your supervisor wrote.
• Response: what the client did after your procedure.

Contrast 2

• Subjective: "Session went badly. Jordan had a meltdown, but I handled it."
• Objective: "At about 2:10 p.m., after the tablet was put away for the transition to table work, Jordan cried and lay on the floor for about 4 minutes. I followed the transition steps in the plan. Jordan returned to the table and completed 5 of 8 matching trials."

Now change one fact. Suppose the crying began when a sibling took the tablet, not when you put it away. The behavior is the same, but the context is different, and your supervisor may read the event differently. That is why context belongs in the note, not just the behavior.

"I handled it" is also an interpretation. Describing the procedure you used lets your supervisor confirm it matched the plan.

Your employer decides the note format, required fields and deadlines. Follow their template rather than any generic one.

Health, medication and schedule information

Caregivers often share details that may affect a session: "She didn't sleep last night," "He started a new medicine," "We moved session time because of a dentist visit." This information matters. Your role is to record it accurately, not to explain it medically.

There are two honest ways to record it:

• As an observation, if you saw it yourself: "Jordan rubbed eyes and put head on table 4 times in the first 20 minutes."
• As an attributed report, if someone told you: "Caregiver reported Jordan slept about 4 hours last night and started a new prescription this week."

"Attributed" means you name who said it. That keeps the source clear.

Avoid writing a diagnosis ("Jordan has an ear infection") or giving advice ("You could skip the dose on session days"). Diagnosing and advising about medication fall outside a behavior technician's defined role. Pass the information to your supervisor and, where relevant, suggest the caregiver contact the client's medical provider.

Timing matters as much as wording. Document this information and pass it on promptly, using your workplace's procedure. Don't save it for the end of the week or the next scheduled meeting. If it could affect the session you're about to run or are running, such as a medicine started this morning or a session moved to a new time, contact your supervisor before or during that session, as your workplace directs, so they can decide whether anything should change. If the information raises a safety concern, follow the urgent steps in the next section. Your employer sets the exact channel and deadline.

Why the rush? Your supervisor reads data to judge whether the program is working. If a client slept 4 hours or started a new medicine, a bad day of data may have nothing to do with the program. Your supervisor can only account for that if they know in time.

Checkpoint 1

A caregiver says, "I think she's coming down with the flu; she's been coughing." During session, you count each cough as it happens and record a total of 6 on your data sheet. Which note is best?

• A) "Client has the flu."
• B) "Client seemed sick and unmotivated."
• C) "Caregiver reported she thinks client may be getting the flu. Client coughed 6 times during session."
• D) "Recommended caregiver give cough medicine before next session."

Answer: C

C separates the caregiver's report, which is credited to the caregiver, from your own observation, which is the count of coughs you actually made. A turns a report into a diagnosis. B adds two interpretations, "seemed sick" and "unmotivated," without evidence. D gives medication advice, which is outside your role. The tempting mistake is treating "the caregiver said flu" as permission to write "flu." A reported illness is still a report, not a diagnosis. Notice also that the number 6 is there only because you counted and recorded it. If you hadn't counted, you would write "coughed several times" rather than invent a number. Finally, writing the note isn't the last step: pass the information to your supervisor promptly under your workplace's procedure, because illness can affect today's session and data.

Getting concerns to the right person

Questions and concerns about your services go to your supervisor. That includes concerns from caregivers and coworkers, not just your own. You also follow your supervisor's direction when you carry out the plan.

Data irregularities are patterns that look wrong. Examples include a sudden jump in a behavior, a program that suddenly seems too easy, or data that doesn't match what you observed. Report what you noticed. Keep running the plan as written until your supervisor gives new direction.

Changing the plan yourself is a mistake even if your supervisor is hard to reach. A delay in reaching them is a reason to keep trying and to use your organization's backup contacts. It is not permission to redesign the program.

Timing depends on the concern:

• Routine: A caregiver asks whether a goal could be added. Pass it on and record that you did.
• Prompt: Data looks unusual, or a caregiver says the plan isn't working. Don't hold it for a scheduled meeting if it affects current sessions.
• Urgent: There is risk of harm to the client, or a possible violation of their rights. Act to protect the client now. Report to your supervisor, follow your organization's policy, and document what you did. Some situations require contacting authorities. You're also responsible for knowing and following mandated-reporting requirements where you work. These never wait for a routine meeting.

Checkpoint 2

It's Friday, and your supervisor is unreachable until a team meeting Tuesday. For three sessions, the client has gotten every trial correct on a program the plan says should be challenging. Another technician suggests skipping ahead to the next program. What should you do?

Answer: Report it without changing the plan

Keep running the program as written. Record the data accurately. Contact your supervisor or the backup contact your organization names, and say exactly what you've seen. Don't skip ahead. Unexpected data is something to report, not a reason to change the plan on your own. Waiting until Tuesday may also be too slow if this affects current sessions, so send it now. If the situation involved a safety risk instead, you would follow urgent procedures right away.

Checkpoint 3

Decide whether each situation is routine, prompt or urgent, and say what you would do.

1. A teacher emails you a suggestion: practice the client's greeting skill at recess, too.
2. Before your session starts, a caregiver tells you the client began a new medicine this morning and "seems really sleepy."
3. During a community outing, the client suddenly walks toward a busy street.

Answer: Routine, prompt, urgent

1 is routine. It's a suggestion from someone on the client's team, with no effect on today's session. Pass it to your supervisor through your usual channel and record that you did. Routine doesn't mean "whenever" or "never": it still goes to your supervisor soon. The tempting mistake is starting recess practice yourself because it sounds helpful. Adding a new setting changes the plan, and that decision belongs to your supervisor.

2 is prompt. A new medicine could affect the session you're about to run. Record it as an attributed report ("Caregiver reported client started a new medicine this morning and seems really sleepy"), then contact your supervisor before or during the session, as your workplace directs. The tempting mistakes are waiting for the next meeting, or telling the caregiver to change the dose.

3 is urgent. There is a risk of harm right now. First take the protective steps your plan and organization's procedures call for. Then report to your supervisor, follow your organization's policy, and document what happened and what you did. The tempting mistake is reaching for your phone to message your supervisor first. Protection comes before reporting, and reporting still has to follow.

What separates the three? Ask two questions. Is anyone at risk of harm right now? If yes, it's urgent. If not, could it affect current sessions? If yes, it's prompt. Otherwise, it's routine.

Correcting records and protecting privacy

Everyone makes mistakes, such as a wrong count or the wrong date. Fix them using your employer's correction procedure. If information you already submitted to your supervisor or employer was inaccurate, contact them immediately, as soon as you become aware of it, to correct it. As part of that contact, work out with them whether the situation needs to be self-reported to the BACB (the Behavior Analyst Certification Board, which certifies RBTs). Not every correction will need that, but it's a question you check rather than skip. Never quietly rewrite a record so an error disappears. Honest records matter more than tidy ones.

Confidentiality means client information is shared only when sharing is authorized and necessary for the work. Follow your employer's and the law's privacy rules. Discuss client information only under your supervisor's direction, unless the law allows sharing for a valid reason such as protecting someone from harm. Include only necessary details in emails and notes. Never post identifying information, including photos, videos or written details, on social media or websites.

Checkpoint 4

Yesterday you submitted a note saying the client completed 8 of 8 trials. Today you notice your data sheet shows 5 of 8. What should you do?

• A) Open the submitted note, change 8 to 5, and say nothing, since the record is now right.
• B) Leave it. The difference is small and the next session's data will balance it out.
• C) Contact your supervisor as soon as you notice, explain the error, and correct it through your employer's correction procedure. In your message, include only what's needed to identify the record and the error.
• D) Post a message in a staff group chat, including coworkers who don't work with this client, with the client's full name and the session details, so everyone knows about the fix.

Answer: C

C does two things at once: it corrects the error openly and immediately, and it limits what is shared to what the work requires. When you contact your supervisor, also confirm with them whether this needs to be self-reported to the BACB. A fixes the number but hides that an error occurred. Your supervisor may already have used the wrong number to make decisions, so they need to know. B leaves a known inaccuracy in the record, and inaccurate data can mislead your supervisor about whether the program is working. D shares identifying details with people who don't need them for their work and haven't been authorized to receive them. The tempting mistake is thinking a correct final number is all that matters. An honest record also shows that it was corrected.

Recap

• Write what could be seen or heard. Leave the conclusions to evidence.
• Notes connect behavior, context, procedure and response.
• Record health, medication and schedule information as observations or attributed reports, and pass it on promptly. Never diagnose or advise.
• Route concerns and odd data to your supervisor, and keep following the plan.
• Safety risks need protective action right away. Mandated-reporting matters need prompt action under the applicable reporting law and your organization's procedure. Neither waits for a routine meeting.
• Correct errors openly and immediately, check whether BACB self-reporting is needed, and share only information that is authorized and necessary, with the right people.

Practice: Rewrite this note objectively, then list what you would tell your supervisor: "Client was in a bad mood because her dad left for work, so I let her take extra breaks."

Answer: Find what's missing, write only what you know, then report

What's wrong with the original:

• "Bad mood" is an interpretation. The note never says what the client actually did.
• "Because her dad left for work" claims a cause. Even if the father left just before, that would show timing, not cause. Leave the connection for your supervisor to judge.
• "I let her take extra breaks" describes a procedure, but not how many breaks, how long, or whether the plan includes them.
• The client's response after the breaks is missing entirely.

A note using only the facts given:

"I gave the client extra breaks."

That is the only part of the original note you can enter as fact. The father's departure can't go in yet, even without the "because." The original note doesn't say when he left, whether it happened during the session, or whether you saw it yourself or someone told you. Writing "father left for work during the session" would add a time and a source the note never supplied.

This note is short because the original is missing most of the evidence. Don't fill the gaps by guessing. Writing "client cried for 5 minutes" when you don't remember that would be inventing data. Before submitting, add only what you actually observed or recorded:

• What the client did, in observable terms, and when.
• Whether and when the father left. If you saw it, record it as your observation. If someone told you, attribute it ("Caregiver reported…"). If you don't know, leave it out.
• How many breaks you gave and how long they lasted.
• What the client did after the breaks.

If you don't know a detail, leave it out or say it wasn't recorded.

What to tell your supervisor:

• That you gave extra breaks, and whether the plan includes them. If it doesn't, you changed the procedure without direction. Say so plainly and promptly, because it affects current sessions. Don't wait for a scheduled meeting.
• What you observed, and what you actually know about the father leaving: when it happened and whether you saw it or were told. Your supervisor decides whether it's connected.
• Ask for direction on what to do if this happens again.

The tempting mistake is deleting "bad mood" and calling the note fixed. The breaks are the bigger issue: a possible plan change your supervisor needs to hear about.
