Session Comparison

The comparison screen lets you analyze multiple sessions for the same student across time. Use it to assess progress, detect phase-related changes, and build the evidence base for a report.

Accessing comparison

There are two ways to open the comparison screen:

• From the Student Hub, select a student and choose “Compare sessions” from the session list menu. You can pre-select specific sessions by checking their rows before clicking.
• From the Results screen, click “Compare sessions” — the current session is pre-selected and you add others from there.

Selecting sessions

The comparison screen shows a session selector at the top. Sessions are listed in date order. Check or uncheck sessions to include or exclude them from the comparison. You can also filter by:

• Phase — show only baseline sessions, only intervention sessions, or a specific condition label

There is no hard limit on how many sessions you can include, but three to eight sessions is the typical range for a school-based evaluation.

Trend charts

Trend charts show behavior data across sessions in a single view. Each behavior gets its own row. Within each row:

• Each session appears as a data point at its recording date
• An optional trend line shows the direction of change over time
• Phase change markers are drawn as vertical lines using the condition labels from your sessions
• Click any data point to open that session’s full results in a slide-over panel

Trend charts appear for all session types that produce quantitative behavior data (interval, frequency, duration, peer comparison, discrete trial).

ABC analysis tools

ABC tools appear only when the selected student has at least one session recorded with the ABC or Narrative method. They include:

• Heatmaps — a grid showing how often each antecedent-consequence pair co-occurred. Darker cells indicate higher frequency. Useful for quickly spotting the most common A-C combinations.
• Sankey flow diagrams — a flow visualization tracing the path from antecedents through behaviors to consequences across all selected sessions. Width of each band corresponds to frequency.
• Top chains — a ranked list of the most common A→B→C sequences observed across sessions, with counts.
• Shift callouts — highlights when the pattern of antecedents or consequences changes meaningfully between phases, indicating a possible intervention effect or environmental change.

Activity-level comparison

Activity-level comparison appears only when activity context was recorded during sessions (using the activity context feature during interval or duration recording). When available, this panel breaks down behavior rates by activity type (e.g., independent seatwork, small group, transitions) so you can compare how behavior differs across instructional contexts, both within and across sessions.

Exporting

From the comparison screen you can export:

• PDF — the full comparison view formatted as a report-ready document, including trend charts and any ABC visualizations
