Which Areas Does the ImPACT Test For?
In each column of the report, you’ll see scores for six areas. The first five are Composite Scores that measure:
- Verbal Memory.
- Visual Memory.
- Visual Motor Speed.
- Reaction Time.
- Impulse Control.
The last score, Total Symptom Score, represents your total out of all 22 symptom descriptors.
What Do the Numbers in the Columns Represent?
In the first four rows under Composite Scores, each column contains two numbers:
- Your raw score
- A percentage indicating how your score compares to other people who are the same age and gender as you
In the Baseline column:
| For most children who: | We expect the second number to be: |
|---|---|
| Get As and Bs in school | 65 to 75% or higher |
| Get Bs and Cs in school | 30 to 40% or higher |
| Get Ds and Fs in school | 20% or higher |
| Have a diagnosed learning disability | 20% or higher |

How Are My Scores Calculated?
The five composite scores are calculated from the raw data from your performance on the various activities of the ImPACT computer test:
- Word Memory.
- Design Memory.
- X’s and O’s.
- Color Match.
- Three Letters Test.
Each Composite Score Is Calculated as Follows:
The Verbal Memory Composite score (as percent correct) is comprised of the average of the following scores:
- Word Memory: Total percent correct.
- Symbol Match: Total correct (hidden).
- Three Letters: Percent of total letters correct.
The Visual Memory Composite score (as percent correct) is comprised of the average of the following scores:
- Design Memory: Total percent correct.
- X’s and O’s: Total correct (Memory) ÷12, then multiply by 100
The Visual Motor Speed Composite (Processing Speed) score is comprised of the average of the following scores:
- X’s and O’s: Total correct (Interference) ÷4
- Three Letters: Average counted correctly x3
The Reaction Time Composite score (in seconds) is comprised of the average of the following scores:
- X’s and O’s: Average correct RT (interference).
- Symbol Match: Average correct RT (visible) ÷3
- Color Match: Average correct RT.
The Impulse Control Composite score is comprised of the total of the following scores:
- X’s and O’s: Total incorrect (Interference).
- Color Match: Total commissions.
How Do I Know If My Performance Is Getting Better or Not?
A better performance on each composite test is indicated by:
- A higher score for:
- Verbal Memory.
- Visual Memory.
- Visual Motor Speed.
- A lower score for:
- Reaction Time.
- Impulse Control.
- Total Symptom Score (indicates that you endorsed fewer symptoms).
