Illuminate Locked Browser is a custom browser that locks down the testing environment within Illuminate Online Testing. The browser is created by and licensed for use from Respondus. When students use the Locked Browser they are unable to print, copy, go to another URL, or access other applications. When an assessment is started, students are locked into it until they submit it for grading.

We've created this downloads page as a resource for downloading and installing the Illuminate Locked Browser. You'll be able to find all the current versions of Illuminate Locked Browser. If you are not a district or site tech, please talk with someone at your district or site before installing any of these programs.

For more information about the Online Testing system, please check out the Online Testing section of our help system.
