Product summary

Review the store description, core capabilities, and common use cases.

When a teacher or admin assigns an assignment or assessment in Castle Learning, they may enable an option to Enable Browser Lockdown. If they have enabled that option AND this extension is installed on the device that the student is using to complete the assignment or assessment, it will close all other tabs and will not allow the student to open a new tab or browser window.
