Logging the hour is the easy part. Writing the line that says what you actually did, in words that still make sense to a supervisor signing the month and to you three years later, is where people stall.
These are model descriptions you can adapt, in two parts. Direct service comes first, grouped by the kind of session, because that is most of what gets logged. Everything else is grouped by the domains of the BCBA Test Content Outline, so the set covers the breadth of the work rather than the few activities that come to mind at the end of a long day.

How to use these
Replace the bracketed parts with your own client, program or behavior, and keep whatever actually happened. A description earns its place when it says what you did, ties it to a client, and leaves something a reader can picture.
Write them the way you would say them out loud. A line that reads like the task list it came from is harder to write and no more useful than one that just says what happened.
The tag on each line is the split it usually falls under. That is a judgment your supervisor makes, not a rule these descriptions can settle. Restricted vs unrestricted hours explains how the two questions work.
These are writing prompts, not a compliance checklist. The Test Content Outline describes what the exam covers; it is not a list of approved fieldwork activities, and matching one does not make an hour count.
Direct service
Running the session is restricted time, and it is a large part of most records. These are ways to describe it that still say something, so a month of direct work does not read as forty identical lines.
Teaching sessions
Restricted
Ran [client]'s programs for the session and took data on each one. [program] is close to mastery, the rest held where they were.
Restricted
Worked through today's targets with [client] in the natural environment rather than at the table, since that is where the skill has to hold up.
Restricted
Block of discrete trials on [program] with [client], recording correct and prompted responses trial by trial.
Restricted
Covered [n] programs with [client] today. Nothing unusual came up and the data went in at the end of the session.
Restricted
Session with [client] following the plan as written. [behavior] did not come up at all today, which is new.
Restricted
Taught [target] with [client] at the prompting level the plan specifies, and faded to [level] by the end of the session.
Behavior plan implementation
Restricted
Ran [client]'s behavior plan through the session, including the replacement behavior and what we do when [behavior] happens.
Restricted
Followed the communication training protocol with [client] today. He asked for a break [n] times without being prompted.
Restricted
Used the antecedent strategies from [client]'s plan through the morning routine, which is when [behavior] usually shows up.
Restricted
Delivered the differential reinforcement procedure as written during [activity] and logged every instance of [behavior].
Restricted
Held the extinction component through [behavior] in session, which took longer today than it has been.
Restricted
Ran the token system with [client] across the session and exchanged at the points the plan sets out.
Daily living and self-care
Restricted
Worked on [skill] with [client] using the task analysis. He is independent through step [n] and still needs a prompt at the handover.
Restricted
Ran the toileting schedule with [client] across the session and recorded each scheduled check.
Restricted
Practiced [skill] with [client] inside the normal routine rather than setting it up as a separate activity.
Restricted
Followed the feeding protocol with [client] at lunch, including the presentation order the plan specifies.
Restricted
Chaining session on [skill] with [client], working backward from the last step as the program sets out.
Home, school and community
Restricted
Session at home with [client]. Same programs as clinic, but the distractions are different and the data show it.
Restricted
Supported [client] at [setting] and ran the plan there. Harder to hold the schedule outside the clinic.
Restricted
Ran [client]'s programs in the classroom alongside what the teacher had planned, so the targets fitted into the lesson.
Restricted
Community session with [client] practicing [skill] in a real setting rather than a rehearsed one.
Restricted
Worked with [client] through the transition between activities, which is where the plan expects trouble.
Group and social programs
Restricted
Ran the social skills group with [n] clients, implementing the group plan as written.
Restricted
Supported [client] inside the group session and prompted at the level his plan specifies.
Restricted
Ran the peer-pairing activity with [client] and one peer, following the protocol.
Data collection during service
Restricted
Took frequency data on [behavior] while running [client]'s session, as the program requires.
Restricted
Recorded duration for [behavior] through today's session as part of the ongoing data collection.
Restricted
Scored [program] trial by trial during the session so the graph stays current.
Restricted
Collected the daily probe on [target] with [client] before starting teaching, the way the plan sets out.
Assessments someone else designed
Restricted
Ran the preference assessment [supervisor] asked for before the session and used the result to pick today's reinforcers.
Restricted
Carried out the probe sequence for [program] exactly as written and passed the results back.
Restricted
Collected the ABC data [supervisor] asked for on [behavior], without analyzing it myself.
Starting and ending a session
Restricted
Spent the first part of the session pairing with [client] before moving into programs.
Restricted
Used the session's closing routine with [client], which the plan treats as a target in its own right.
Restricted
Followed [client]'s safety plan when [behavior] escalated, then documented what happened and when.
C. Measurement, Data Display, and Interpretation
C.1Create operational definitions of behavior.
Unrestricted
Rewrote how we define [behavior] for [client] so everyone scores it the same way. Added examples and non-examples, then checked agreement with [RBT] on a session.
Unrestricted
Two of us scored the same session differently, so I tightened the definition of [behavior] and sent the new one to the team.
C.2Distinguish among direct, indirect, and product measures of behavior.
Unrestricted
Compared what the permanent product shows against what we record in session for [program], and recommended we keep one and drop the other.
Unrestricted
Checked what caregivers report about [behavior] against the session data, and wrote up where the two do not line up.
C.3Measure occurrence.
Either
Counted [behavior] across [n] sessions with [client] to answer whether it is actually getting more frequent or just more noticeable.
Unrestricted
Converted the counts for [behavior] to rate per hour so sessions of different lengths could be compared honestly.
C.4Measure temporal dimensions of behavior (e.g., duration, latency, interresponse time).
Either
Timed [behavior] with [client] across the week and worked out the average and the range, because the count alone was not telling us much.
Either
Measured how long [client] takes to respond after the instruction in [program], to see whether the prompt is coming too fast.
C.5Distinguish between continuous and discontinuous measurement procedures.
Unrestricted
Worked out that partial interval was inflating [behavior] for [client] and explained to the team why we were switching.
Unrestricted
Changed [program] to continuous recording because the behavior was short enough that the intervals were missing it.
C.6Design and apply discontinuous measurement procedures (e.g., interval recording, time sampling).
Unrestricted
Set up momentary time sampling for [behavior] with [client] and tried it across three sessions before rolling it out.
Unrestricted
Chose the interval length for recording [behavior] and showed the staff on the case how to use the new sheet.
C.7Measure efficiency (e.g., trials to criterion, cost-benefit analysis, training duration).
Unrestricted
Counted trials to criterion across [n] targets to see whether the new teaching arrangement was actually faster for [client].
Unrestricted
Worked out how much session time the change to [procedure] was costing us, so the team could decide if it was worth it.
C.8Evaluate the validity and reliability of measurement procedures.
Unrestricted
Scored a session alongside [RBT] to check agreement on [behavior]. We came out at [n]% and went back over the ones we disagreed on.
Unrestricted
Compared the data sheet for [program] against what staff actually record, and fixed the parts nobody was filling in.
C.9Select a measurement procedure to obtain representative data that accounts for the critical dimension of the behavior and environmental constraints.
Unrestricted
Picked how to measure [behavior] for [client], balancing what matters clinically against what a person can realistically record mid-session.
Unrestricted
Switched [behavior] from counting to timing, because the episodes vary in length rather than in number.
C.10Graph data to communicate relevant quantitative relations (e.g., equal-interval graphs, bar graphs, cumulative records).
Unrestricted
Caught up [client]'s graphs for [behavior] and marked where we changed phase, so the trend is readable before the team meeting.
Unrestricted
Put [program] on a cumulative record so the team could see how fast acquisition is actually going.
C.11Interpret graphed data.
Unrestricted
Looked at [client]'s data for level, trend and variability and brought a recommendation to supervision rather than just the graph.
Unrestricted
Read the overlap between phases for [behavior] and wrote up why I think we should hold where we are for another two weeks.
C.12Select a measurement procedure to obtain representative procedural-integrity data that accounts for relevant dimensions (e.g., accuracy, dosage) and environmental constraints.
Unrestricted
Built a short integrity check for [procedure] on [client]'s case, covering whether it is run correctly and often enough.
Unrestricted
Scored how [program] is actually being run at [n]%, fed that back, and retrained the two steps that were slipping.
F. Behavior Assessment
F.1Identify relevant sources of information in records (e.g., educational, medical, historical) at the outset of the case.
Unrestricted
Read through [client]'s records before we started and pulled out what actually matters for programming.
Unrestricted
Went back through earlier reports for [client] and listed what still has not been assessed.
F.2Identify and integrate relevant cultural variables in the assessment process.
Unrestricted
Talked with the family about routines, language and what they want for [client], and changed the assessment plan to match.
Unrestricted
Swapped the assessment materials for items the family actually uses at home, so the result means something.
F.3Design and evaluate assessments of relevant skill strengths and areas of need.
Unrestricted
Ran the [VB-MAPP / ABLLS-R / AFLS] with [client], scored it, and wrote the summary for the plan renewal.
Unrestricted
Probed across [n] areas with [client] to check whether the assessment from six months ago still holds.
F.4Design and evaluate preference assessments.
Unrestricted
Ran a paired-stimulus preference assessment with [client], ranked [n] items, and updated the reinforcer list from the result.
Unrestricted
Ran an MSWO before sessions for a week because progress had stalled and I suspected the reinforcer had gone stale.
F.5Design and evaluate descriptive assessments.
Unrestricted
Collected ABC data across [n] sessions for [behavior] to work out what is keeping it going.
Unrestricted
Watched [behavior] in the classroom across the week and wrote up what seems to set it off and what follows it.
F.6Design and evaluate functional analyses.
Unrestricted
Helped run the functional analysis for [client], took the data across conditions and graphed the results afterwards.
Unrestricted
Planned the condition order for a functional analysis of [behavior] and went through it with my supervisor before we ran it.
F.7Interpret assessment data to determine the need for behavior-analytic services and/or referral to others.
Unrestricted
Went through the assessment results for [client] and recommended a referral to [discipline] alongside what we are doing.
Unrestricted
Pulled the assessment data together to make the case that [client] needs services, and what kind.
F.8Interpret assessment data to identify and prioritize socially significant, client-informed, and culturally responsive behavior-change procedures and goals.
Unrestricted
Picked [n] goals for [client] from the assessment, with the family telling us which ones matter most at home.
Unrestricted
Reordered [client]'s goals after the family said the priority was different from what the assessment suggested.
G. Behavior-Change Procedures
G.1Design and evaluate positive and negative reinforcement procedures.
Unrestricted
Wrote the reinforcement part of [client]'s new program: what he earns, how often, and for what.
Unrestricted
Three flat sessions in a row, so I checked whether the reinforcer was still working and changed it.
G.2Design and evaluate differential reinforcement (e.g., DRA, DRO, DRL, DRH) procedures with and without extinction.
Unrestricted
Wrote a DRA procedure for [behavior], including what we want instead and what happens when the old behavior occurs.
Unrestricted
Looked at [client]'s DRO data and recommended we stretch the interval, with the reasoning written down.
G.3Design and evaluate time-based reinforcement (e.g., fixed-time) schedules.
Unrestricted
Set up a fixed-time delivery schedule for [client] to get through the gaps between teaching, where [behavior] tends to appear.
Unrestricted
Reviewed how the time-based schedule has gone over two weeks and recommended thinning it.
G.4Identify procedures to establish and use conditioned reinforcers (e.g., token economies).
Unrestricted
Built the token system for [client]: what a token buys, what backs it up, and how we fade it later.
Unrestricted
Checked the exchange data for [client] and changed the ratio, because he had stopped caring about the backup.
G.5Incorporate motivating operations and discriminative stimuli into behavior-change procedures.
Unrestricted
Rewrote the antecedent section of [client]'s plan so the setup happens before the teaching block, not during it.
Unrestricted
Added a clear signal to [program] so staff all indicate availability the same way.
G.6Design and evaluate procedures to produce simple and conditional discriminations.
Unrestricted
Wrote the conditional discrimination program for [client], including array size and how the field rotates.
Unrestricted
Looked at where [client] keeps making errors in [program] and found an unintended cue in the materials.
G.7Select and evaluate stimulus and response prompting procedures (e.g., errorless, most-to-least, least-to-most).
Unrestricted
Chose a most-to-least hierarchy for [program] and wrote down exactly when staff move between levels.
Unrestricted
Compared errorless teaching against least-to-most for [target] and recommended one, with the reasons.
G.8Design and implement procedures to fade stimulus and response prompts (e.g., prompt delay, stimulus fading).
Unrestricted
Designed the prompt-delay steps for [program] and the criteria staff use to move to the next one.
Unrestricted
Checked [client]'s prompt-level data and moved [program] on to the next fading step.
G.9Design and evaluate modeling procedures.
Unrestricted
Set up video modeling for [skill] with [client] and recorded the model clip.
Unrestricted
Checked whether the model in [program] was actually producing imitation, and changed how it is presented.
G.10Design and evaluate instructions and rules.
Unrestricted
Wrote the exact wording staff use for [program], so [client] hears the same instruction from everyone.
Unrestricted
Cut the instructions in [client]'s plan down after staff said they were too long to use mid-session.
G.11Shape dimensions of behavior.
Unrestricted
Planned the shaping steps for [behavior] with [client] and what counts as good enough at each one.
Unrestricted
Moved the shaping criterion on for [client] after the current step held for [n] sessions.
G.12Select and implement chaining procedures.
Unrestricted
Wrote a [n]-step task analysis for [skill], tried it with [client], and rewrote the three steps that were too big.
Unrestricted
Decided between forward and backward chaining for [skill] with [client] and wrote down why.
G.13Design and evaluate trial-based and free-operant procedures.
Unrestricted
Set up a free-operant arrangement for [target] and compared it against how we were running it before.
Unrestricted
Worked out whether [program] is better taught in blocks or spread through the session, and changed it.
G.14Design and evaluate group contingencies.
Unrestricted
Designed a group contingency for the classroom that includes [client], and set what the group has to do.
Unrestricted
Reviewed how the group contingency has gone and recommended changing the criterion.
G.15Design and evaluate procedures to promote stimulus and response generalization.
Unrestricted
Wrote the generalization plan for [skill]: which settings, which people, which materials we probe.
Either
Probed [skill] with [client] in [n] other settings and wrote up where it held and where it did not.
G.16Design and evaluate procedures to maintain desired behavior change following intervention (e.g., schedule thinning, transferring to naturally occurring reinforcers).
Unrestricted
Wrote the maintenance plan for [mastered skill], including how often we check back.
Unrestricted
Planned how to thin [program] and hand it over to what naturally reinforces it.
G.17Design and evaluate positive and negative punishment (e.g., time-out, response cost, overcorrection).
Unrestricted
Drafted the response-cost section of [client]'s plan with the safeguards and the review date it needs.
Unrestricted
Looked at the data on the restrictive component for [client] and recommended taking it out.
G.18Evaluate emotional and elicited effects of behavior-change procedures.
Unrestricted
Watched for emotional side effects while we ran extinction with [client] and reported what I saw.
Unrestricted
Read back through session notes after the procedure change to see whether anything unwanted turned up.
G.19Design and evaluate procedures to promote emergent relations and generative performance.
Unrestricted
Set up matrix training for [client] to see whether untaught combinations would come out on their own.
Either
Probed the relations we never taught [client] after equivalence training, and recorded which ones emerged.
H. Selecting and Implementing Interventions
H.1Develop intervention goals in observable and measurable terms.
Unrestricted
Wrote [client]'s goals so they can actually be scored: what the behavior is, where it starts, and what counts as done.
Unrestricted
Rewrote [n] goals in [client]'s plan that two people would have scored differently.
H.2Identify and recommend interventions based on assessment results, scientific evidence, client preferences, and contextual fit (e.g., expertise required for implementation, cultural variables, environmental resources).
Unrestricted
Recommended [procedure] for [client] based on the assessment, the evidence, and what this setting can realistically run.
Unrestricted
Compared two options for [behavior] on how well they fit the setting, and took the comparison to supervision.
H.3Select socially valid alternative behavior to be established or increased when a target behavior is to be decreased.
Unrestricted
Chose the replacement behavior for [behavior] with [client] and wrote down why that one and not another.
Unrestricted
Checked with the family that the alternative we picked for [client] is one they actually want at home.
H.4Plan for and attempt to mitigate possible unwanted effects when using reinforcement, extinction, and punishment procedures.
Unrestricted
Wrote down what could go wrong with the extinction component in [client]'s plan and what staff do if it does.
Unrestricted
Added a mitigation step to [client]'s plan for the side effect the team had raised.
H.5Plan for and attempt to mitigate possible relapse of the target behavior.
Unrestricted
Planned for [behavior] coming back with [client], including what we do if it does.
Unrestricted
Adjusted [client]'s plan after the setting changed, to reduce the chance of losing the gains.
H.6Make data-based decisions about procedural integrity.
Unrestricted
Looked at the integrity data for [program] and concluded the plan is fine, the training is not.
Unrestricted
Used the integrity numbers to explain why [program] is not working and what to do about it.
H.7Make data-based decisions about the effectiveness of the intervention and the need for modification.
Unrestricted
Wrote the case for changing [program] to a leaner schedule, pointing at the data rather than the impression.
Unrestricted
Put together [client]'s monthly summary across [n] programs with what I would change and why.
H.8Collaborate with others to support and enhance client services.
Unrestricted
Met the [SLP / OT / teacher] about [client] so we are prompting the same way across services.
Unrestricted
Presented [client]'s data at the team meeting and recommended the changes, rather than just reporting them.
I. Personnel Supervision and Management
I.2Identify and apply strategies for establishing effective supervisory relationships (e.g., executing supervisor-supervisee contracts, establishing clear expectations, giving and accepting feedback).
Unrestricted
Sat down with [RBT] to agree expectations and a meeting schedule, and wrote it down so we both have it.
Unrestricted
Gave [RBT] feedback on [procedure] and asked for some back, then recorded what we agreed to change.
I.3Identify and implement methods that promote equity in supervision practices.
Unrestricted
Looked at how supervision time is spread across the team and evened it out, because two people were getting most of it.
Unrestricted
Rewrote the training materials so they work for staff with very different levels of experience.
I.4Select supervision goals based on an assessment of the supervisee's skills, cultural variables, and the environment.
Unrestricted
Watched [RBT] run [procedure] and set supervision goals from what I actually saw rather than what was asked for.
Unrestricted
Built a competency checklist for [procedure] on [client]'s case and used it to decide what to train first.
I.5Identify and apply empirically validated and culturally responsive performance-management procedures (e.g., modeling, practice, feedback, reinforcement, task clarification, manipulation of response effort).
Unrestricted
Trained [n] RBTs on [client]'s [procedure] with instruction, modeling, practice and feedback until they hit criterion.
Unrestricted
Modeled [procedure] for [RBT], had them practice it, and scored how it went afterwards.
I.6Apply a function-based approach (e.g., performance diagnostics) to assess and improve supervisee behavior.
Unrestricted
Worked out why [procedure] is not being run as written before retraining anyone. It was the data sheet, not the skill.
Unrestricted
Made [procedure] easier to do after working out the barrier was effort rather than knowledge.
I.7Make data-based decisions about the efficacy of supervisory practices.
Unrestricted
Compared fidelity before and after training [RBT] to check whether my supervision actually changed anything.
Unrestricted
Looked at how supervision has gone across the team this month and changed my approach for next month.
E. Ethical and Professional Issues
Only the tasks describing something a trainee does appear here. Note too that the Handbook excludes conferences, workshops and university courses from fieldwork entirely, so reading and consultation count only when they are tied to a specific client's programming.
E.3Develop and maintain competence by engaging in professional development activities (e.g., read literature, seek consultation, establish mentors).
Unrestricted
Got stuck on [problem] with [client], so I spent an hour in the literature instead of guessing and wrote up what to try.
Unrestricted
Asked [role] for consultation on [client]'s case and noted what changed in the plan as a result.
E.4Identify and comply with requirements for collecting, using, protecting, and disclosing confidential information.
Unrestricted
Checked how [client]'s data are stored and shared, and fixed the part that was not meeting requirements.
Unrestricted
Prepared the records release for [client] and confirmed what we can share and with whom.
E.6Identify the conditions under which services or supervision should be discontinued and apply steps for transitioning clients and supervisees to another professional.
Unrestricted
Drafted the transition plan for [client], including the fading schedule and what the next team needs to know.
Unrestricted
Wrote the handover notes for [client] and walked the receiving team through them.
E.8Identify and apply interpersonal and other skills (e.g., accepting feedback, listening actively, seeking input, collaborating) to establish and maintain professional relationships.
Unrestricted
Met the family to hear what is not working about [client]'s plan, and agreed what we would change.
Unrestricted
Asked the staff running [client]'s program what they would change before I rewrote it.
E.10Apply culturally responsive and inclusive service and supervision activities.
Unrestricted
Changed [client]'s targets so they use the family's language and fit how their day actually runs.
Unrestricted
Adjusted how I supervise [RBT] after they told me what was not working about it.
E.12Identify and apply the legal, regulatory, and practice requirements (e.g., licensure, jurisprudence, funding, certification) relevant to the delivery of behavior-analytic services.
Unrestricted
Checked what the funder requires for [client] and changed our documentation to meet it.
Unrestricted
Looked up what the state requires for [client]'s services and noted what applies to us.
Nothing matches that search. Try a single word such as graph, prompt or caregiver.
Write it once, in the right place
FieldworkABA keeps the description with the entry it belongs to, so the month you sign carries the detail rather than a row of hours. Descriptions support dictation, which is usually faster than typing between sessions.
Source. Domain and task wording from the Behavior Analyst Certification Board, BCBA Test Content Outline (6th ed.), effective January 1, 2025. Domains A, B and D are absent on purpose: they describe knowledge rather than activities a trainee would log. Direct service is grouped by session type rather than by task, because the outline describes designing and evaluating rather than delivering. The restricted and unrestricted definitions are from the BCBA Handbook.
