You'll likely see your child's RBT or BCBA recording data during sessions — quick notes, tally marks, or entries on a tablet. Understanding what's actually being tracked, and why, can help you engage more meaningfully with your child's progress.
Why Data Collection Matters
ABA is a data-driven discipline — decisions about your child's treatment plan are meant to be based on objective, measured information, not just general impressions of how things seem to be going. Consistent data collection is what allows your BCBA to genuinely know whether a specific intervention is working, rather than relying on subjective judgment alone.
Common Types of Behavior Data
Depending on the specific goal, your child's team might track: frequency (how many times a behavior occurs in a given period), duration (how long an episode of behavior lasts), intensity (a rating of how severe a specific instance was), latency (how long it takes a behavior to occur after a specific trigger or instruction), and ABC data (Antecedent-Behavior-Consequence) — recording what happened immediately before a behavior, the behavior itself, and what happened immediately after, which helps identify patterns and function.
Why ABC Data Is Especially Valuable
ABC data is particularly useful because it captures context, not just the behavior in isolation. Reviewing patterns across many ABC recordings often reveals triggers or functions that aren't obvious from any single instance — for example, discovering that a specific behavior consistently follows a particular type of demand, or consistently precedes access to a preferred item.
How Data Informs the Treatment Plan
Your BCBA regularly reviews collected data to answer key questions: Is a target behavior decreasing over time? Is a replacement skill increasing? Are there patterns suggesting the current approach isn't working as intended, or needs adjustment? This ongoing review is what allows treatment plans to be responsive and evolving, rather than static and set-and-forget.
What Data Looks Like Over Time
Progress is typically visualized in graphs showing trends over weeks or months — a downward trend in a behavior of concern, an upward trend in a replacement skill or communication goal. Your BCBA should be willing and able to show you this data directly, not just describe it in general terms. We cover this more broadly in How to Know If ABA Therapy Is Working for Your Child.
Data Collection Shouldn't Disrupt Sessions
Well-designed data collection happens efficiently in the background of a session — quick notation methods that don't require stopping the flow of an activity to record extensive notes. If data collection seems to be significantly disrupting your child's actual therapy time, that's worth raising with your BCBA.
You Can — and Should — Ask to See It
You're entitled to review your child's progress data directly, in a format you can understand. If data is only described to you verbally in vague terms ("things are going well"), it's reasonable to ask to see the actual data and graphs behind that statement.
