Overview
Documentation and reporting are foundational responsibilities of a Registered Behavior Technician (RBT). This domain covers how to accurately collect and record behavioral data, write objective session notes, maintain client confidentiality under HIPAA, and communicate critical information to supervising BCBAs. Mastery of these skills ensures treatment integrity, client safety, and ethical practice.

1. Data Collection Methods
Overview
RBTs must select and apply the correct measurement system based on the characteristics of the target behavior. Choosing the wrong method can distort data and lead to poor clinical decisions.
Time-Based Recording Methods
| Method | What It Measures | Best Used For |
|---|---|---|
| Partial Interval Recording | Whether behavior occurred at any point during interval | Lower-rate behaviors (but overestimates!) |
| Momentary Time Sampling | Whether behavior is occurring at the exact end of interval | High-rate or long-duration behaviors |
| Duration Recording | How long a behavior lasts (start to finish) | Behaviors where length matters (e.g., tantrums) |
| Latency Recording | Time between stimulus/prompt and start of behavior | Instruction compliance, response time |
Frequency/Event Recording
• Frequency (Event) Recording: Counts the total number of discrete behavior occurrences during an observation period
• Best for behaviors with a clear beginning and end (e.g., hits, vocalizations)
Key Terms
• Partial Interval Recording – Behavior scored as occurring if it happens at any point within the interval
• Momentary Time Sampling – Behavior scored only at the precise end of the interval
• Frequency Recording – Total count of discrete behavior occurrences
• Duration Recording – Total time a behavior lasts from start to finish
• Latency Recording – Time from stimulus presentation to the beginning of the response
Key Distinction: Duration vs. Latency
• Duration = How long the behavior lasts (start → stop)
• Latency = How long before the behavior starts (stimulus → behavior begins)
> Example: A teacher says "sit down" (stimulus). The time until the student begins sitting = latency. The time the student remains seated = duration.
⚠️ Watch Out For
• Partial interval recording OVERestimates behavior — a behavior that occurred for 1 second in a 30-second interval gets scored as if it occurred the whole time
• Momentary time sampling can UNDERestimate behaviors that end just before the interval ends
• Do not confuse latency (before the behavior) with duration (the behavior itself)
• Frequency recording is not appropriate for behaviors without a clear start and stop (e.g., whining that fades in and out)

2. Session Notes & Documentation
Purpose of Session Notes
Session notes provide an objective, written record of:
• Client behaviors observed
• Interventions implemented
• Client progress toward treatment goals
• Any notable events during the session
They ensure continuity of care and support the BCBA's data-based clinical decisions.
ABC Data Collection
• A – Antecedent: What happened before the behavior (environmental triggers, prompts, instructions)
• B – Behavior: The observable, measurable behavior itself
• C – Consequence: What happened immediately after the behavior (reinforcement, punishment, no response)
> Purpose of ABC data: To identify the function of a behavior (why it's happening)
Writing Objective Notes
Objective documentation means:
• ✅ Describing observable, measurable behaviors in factual language
• ✅ Using specific, concrete terms ("Client hit the table 3 times")
• ❌ No personal interpretations ("Client seemed frustrated")
• ❌ No emotional judgments ("Client was being manipulative")
• ❌ No assumptions about internal states
> Objective: "Client threw materials off the desk twice after being given a non-preferred task."
> Not Objective: "Client had a bad attitude and didn't want to work."
Correcting Documentation Errors
The correct procedure for correcting a written error:
1. Draw a single line through the error (so original is still readable)
2. Initial and date the correction
3. Write the correct information next to or above the error
4. Never use correction fluid (white-out) or completely obscure the original entry
Key Terms
• Session Note – Written record documenting session events, behaviors, and interventions
• ABC Data – Antecedent-Behavior-Consequence recording to identify behavioral function
• Objective Documentation – Factual, observable, measurable language free of interpretation
• Procedural Fidelity – Implementing treatment procedures as designed and written
⚠️ Watch Out For
• Never use white-out on legal/medical documents — it's considered falsification
• Watch for subjective language slipping into notes: words like "seemed," "appeared to feel," "was being" are red flags
• Session notes must be completed promptly after each session — delayed documentation can compromise accuracy

3. Reporting Requirements
Who Does an RBT Report To?
The RBT works under the supervision of a BCBA. Most reporting goes directly to the supervising BCBA first.
Mandatory Reporting Situations
| Situation | Action Required |
|---|---|
| Suspected abuse or neglect | Report to supervising BCBA AND appropriate authorities (e.g., CPS) as required by law |
| Session errors affecting safety or data | Report honestly and promptly to supervising BCBA |
| Environmental/equipment issues | Report to supervising BCBA for treatment modifications |
| Changes in client behavior/health | Report to supervising BCBA |
Why Reporting Matters
• Client safety – Ensures immediate risks are addressed
• Data integrity – Errors caught early prevent compounding inaccuracies
• Treatment fidelity – BCBA can adjust the environment or procedures as needed
• Ethical obligation – Transparency is required by the RBT Ethics Code
Key Terms
• Mandatory Reporter – A person legally required to report suspected abuse or neglect to authorities
• Supervising BCBA – The credentialed professional responsible for overseeing the RBT's work
• Procedural Error – A mistake in implementing treatment as written
⚠️ Watch Out For
• RBTs do not handle reports or communications independently — always involve the supervising BCBA
• Suspected abuse/neglect may require both reporting to the BCBA and reporting to legal authorities — one does not replace the other
• Failing to report errors is an ethical violation, even if the error seems minor

4. Confidentiality & HIPAA
What Is HIPAA?
HIPAA (Health Insurance Portability and Accountability Act) is a federal law that protects the privacy and security of patient health information.
Protected Health Information (PHI)
PHI is any information that:
• Relates to a client's health, treatment, or payment for services AND
• Can be used to identify the individual
Examples of PHI:
• Client's name, address, date of birth
• Diagnosis, treatment records
• Appointment dates and times
• Photos, videos, or audio recordings of the client
Core Confidentiality Rules for RBTs
| Situation | Correct Action |
|---|---|
| Friend asks about a mutual client | Disclose nothing — not even whether the person is receiving services |
| Another professional requests records | Ensure proper written consent/authorization is in place first; follow agency protocols |
| Discussing client information | Only in private, secure settings with authorized personnel |
| Social media | Never post any client information, images, or identifying details |
| Public places (coffee shops, hallways) | Never discuss client cases — risk of unauthorized disclosure |
Sharing Information Appropriately
Before sharing client records or information with another professional:
1. Ensure written consent/authorization from client or legal guardian is obtained
2. Follow your organization's protocols
3. Do not share information independently as an RBT
Key Terms
• HIPAA – Federal law protecting the privacy of health information
• PHI (Protected Health Information) – Identifiable health information requiring legal protection
• Confidentiality – The ethical and legal obligation to protect client information
• Written Authorization/Consent – Legal permission to share specific information with specific parties
• Unauthorized Disclosure – Sharing PHI without proper consent; a HIPAA violation
⚠️ Watch Out For
• Confirming or denying that someone is a client IS a HIPAA violation — you cannot say "yes" or "no"
• Discussing cases with colleagues who aren't involved in that client's care is also a violation
• HIPAA applies to all formats: verbal, written, electronic, and even incidental conversations overheard
• Texts, emails, and social media posts containing PHI are serious violations

5. Graphing & Data Interpretation
Purpose of Graphs in ABA
Graphs provide a visual representation of behavior over time, allowing the BCBA to:
• Monitor client progress
• Identify trends (increasing, decreasing, stable)
• Make data-based clinical decisions
• Compare performance across treatment phases
Anatomy of a Behavior Graph
| Graph Component | What It Represents |
|---|---|
| Y-axis (vertical) | The measurement of the target behavior (frequency, rate, duration, percentage) |
| X-axis (horizontal) | Time (sessions, dates) |
| Data Points | Individual session measurements plotted on the graph |
| Phase Change Line | Vertical line indicating a change in condition (baseline → intervention, etc.) |
Phase Change Lines
• A vertical line drawn on the graph
• Signals a change in treatment condition (e.g., baseline to intervention, change in reinforcement schedule)
• Allows visual comparison of behavior between phases
• Data points are not connected across phase change lines
RBT's Graphing Responsibilities
• Accurately plot data points after each session
• Record data in a timely manner
• Do not alter or manipulate data points
• Report any graphing questions or concerns to the supervising BCBA
Key Terms
• Phase Change Line – Vertical line on a graph marking a change in treatment condition
• Baseline – Phase of measurement before intervention is introduced
• Y-axis – Vertical axis representing behavior measurement
• X-axis – Horizontal axis representing time/sessions
• Data Point – A single plotted value representing behavior in one session
• Trend – The overall direction of data over time (increasing, decreasing, flat)
⚠️ Watch Out For
• RBTs plot data — BCBAs interpret data and make treatment decisions
• Never connect data points across a phase change line
• Data must be plotted accurately and promptly — delayed or estimated plotting compromises clinical decision-making
• The y-axis label tells you what type of measurement is being used — always check it
