Respondus LockDown Browser (RLB)

Creates a “locked” testing environment for Blackboard.

Respondus LockDown Browser is a client application that is installed to a local computer. It provides a custom interface for the Internet Explorer (Windows) or Safari (Macintosh) software that is already installed on the computer. It does not modify an existing copy of Internet Explorer or Safari, but rather, installs a separate program that will display the custom browser when it is started. Respondus LockDown Browser uses the same security features and service packs that are currently installed for Internet Explorer or Safari. Installing Respondus LockDown Browser won't modify the current version of Internet Explorer or Safari in any way.
