# How to test GAT Shield or Teacher Assist defined rules

[**GAT Shield**](https://gatlabs.com/knowledge/tech-tips/gat-shield-overview/) allows a [Google Workspace Admin](https://workspace.google.com/) to test the defined rules and see how they change with time for the particular user.

This option is only available to users who have migrated from the standard version of[Site Access Control](https://gatlabs.com/knowledge/tech-tips/site-access-control-for-chrome-browsing/) in GAT Shield to the new [Site Access Control](https://gatlabs.com/knowledge/tech-tips/block-site-using-site-access-control/) version.

## Test defined rules

To test the defined rules, navigate to **GAT Shield > Site Access Control > Rules > click on Test Rules **

The **Test Rules**section enables you to verify if a specific URL/Website is blocked or not for the selected user.

Enter data in each of the button fields.

- **Website**– Enter the URL you want to check.
