A Grid Response interaction presents a pencil-paper style grid of numbered bubbles to the candidate who fills in the bubbles to represent a single numeric answer.

This type of item interaction is not commonly used in online assessments, but it may be useful if numerical responses are machine-read from paper.
Creating a Grid Response Interaction
To create a Grid Response interaction:
- In the item editor, add a Grid Response interaction type.
- Add content to your stem prompt (ex: "What is the value of pi ...").
- In the field labeled "Scored Responses," enter the correct numerical response and click Add Text.
Add other correct numerical responses if there is more than one correct answer.
By default, correct values receive a score of +1.00 and all other values receive 0 points. If you want to use different scoring, click “Custom Scoring” and then “Edit.” A “Score” text box appears to the right of each value. Enter a different number of points if desired. Refer to Response Scores for more information.
Customizing the Grid
You may change the number of columns in the grid and/or provide symbols for creating fractions, decimal values, or negative numbers.
To customize the grid, click Customize, located in the Grid Response section.
Make any changes to the number of columns in the grid or the symbols offered in the grid.
Click Save. The grid preview displays your customized grid.

By default, all values in the Scored Responses are receive a score of +1.00. If you want to use different scoring, click “Custom Scoring” and then “Edit.” A “Score” text box appears to the right of each scored response. Enter a different number of points if desired.
