If your organization wants to prevent non-admins from searching for training on their own, this page will show you how to remove that option from their main menu bar.
Here's how to toggle on/off the Training Catalog feature in the menu:
An Administrator will need to go to your Organization menu.
Select Organization Settings in the dashboard
Toggle the Show Search in Menu to On or Off
Just a reminder, this turns off Search for everyone in the Organization. Only Admins will be able to navigate to the Training Catalog.
