# Survey Impact Data

Displays pre/post survey impact scores comparing average responses before and after programming.

#### Location

This panel appears on the following dashboards:

* [Unit Snapshot Dashboard](/analyze/impact-dashboards/unit-snapshot-dashboard.md)

#### Modules Included

* Program Activities
* Surveys (Pre/Post evaluations)

#### Filters

**Applied Filters**

* **Viewable records** — Only Program Activities the current user has permission to view are included.
* **Survey delivery types** — Only surveys configured for **Pre** or **Post** delivery are included.
* **Surveys module** — This panel is only visible if the organization has the Surveys module enabled.

**Non-Applicable Filters**

Every filter offered on the Unit Snapshot Dashboard filter bar applies to this panel.

#### Calculations

1. PEARS retrieves all viewable Program Activities that match the current dashboard filters and have the same survey attached as both a pre and a post evaluation.
2. For each survey question that is graphable and scalable — that is, its answer options carry numeric values — the panel calculates:
   * **Pre Average** — The average numeric value of the answer options chosen on pre-survey responses for that question.
   * **Post Average** — The average numeric value of the answer options chosen on post-survey responses for that question.
3. Questions that do not have both a pre and a post average are dropped, as are side-by-side question types.
4. The first five remaining questions are displayed as a grouped horizontal bar chart, with a **Pre-Survey Instrument** bar and a **Post-Survey Instrument** bar for each question and the value axis labeled **Mean**. Hovering a bar shows its average and the number of responses behind it.

#### Additional Notes

* Only numeric/scalable survey questions are included. Open-ended text questions are not displayed.
* Both individually entered responses and surveys attached with aggregate responses feed the averages.
* **View data table** in the chart menu lists every qualifying question, not only the five plotted on the chart.
* This panel is permission-gated and will only appear if the organization has the Surveys module enabled.
