Trial-by-trial data

Trial-by-trial data collection for ABA sessions

Score each trial with one tap, and see percent correct build while the session is still happening. The result goes into the session note and onto the target’s graph, so nobody copies numbers from a paper sheet.

Every session becomes a point on the graph

The percent correct from each session is plotted on the target’s graph, in its baseline and intervention phases. This is a sample with made-up data.

Built for the pace of a discrete-trial session

Large targets, a running count and no totals to add up by hand.

Two taps, one per trial

Tap the check for a correct trial or the cross for an incorrect one. The buttons are large enough to use while you run the session.

Percent correct as you go

See the count of correct and incorrect trials, a row of dots for the trials so far and a bar for the percent correct, updated after every tap.

Trial and percent-correct targets

Targets measured as trial by trial and targets measured as percent correct are collected the same way, so one screen covers both.

Part of the visit’s note

The session’s result is saved with the visit, so the session note, the analyst’s review and the graph all start from the same record.

A graph for every target

Each session is one point: correct trials divided by all trials, from 0 to 100 percent. Baseline and intervention are marked, and a mastery criterion shows what the target is aiming for.

Targets with status and mastery

Every target carries a status (baseline, in treatment, mastered or on hold) and a mastery criterion, so the plan is visible to the whole team.

How trial-by-trial collection works

  1. 1

    Open the visit

    The RBT opens the session’s data screen and picks the skill target.

  2. 2

    Tap each trial

    Tap the check or the cross after every trial. The count, the dots and the percent update as you go.

  3. 3

    Review the graph

    After the session the point appears on the target’s graph, and the BCBA decides what to change.

Frequently asked questions

Can I record prompted trials?

Trial-by-trial data counts each trial as correct or incorrect. To score a skill step by step at each prompt level, use a task analysis.

How is percent correct worked out?

Correct trials divided by all trials in the session, shown from 0 to 100 percent.

Can an RBT collect trial data on a phone or tablet?

Yes. The web app, the iPhone and iPad apps and the Android apps all take session data.

Does the data go into the session note?

Yes. Data collected during a visit is part of that visit’s session note.
