When students take online benchmark assessments in a standard browser (such as Edge, Chrome, Safari, Firefox, etc.), they are still able to access other internet sites and other applications while taking the test. If you want to prevent this for specific assessments at your school, you may force the use of the LockDown Browser® by Respondus, a custom browser that locks the online testing environment by:

  • Displaying assessments full-screen only.
  • Providing only Back, Forward, Refresh, and Stop for browser menus and toolbar options.
  • Preventing access to other applications such as messaging, screen-sharing, virtual machines, and remote desktops (with the optional exception of video conferencing software for remote proctoring).
  • Preventing print and screen capture functions during the test.
  • Preventing copying and pasting during the test.
  • Disallowing right-click menu options, functions keys, keyboard shortcuts, and task switching.
  • Preventing assessments from opening with a standard browser. 

Important: LockDown Browser may only be used for benchmark assessments. You cannot use LockDown Browser for classroom assessments. 

Step 1 - Install LockDown Browser

LockDown Browser OEM is provided to you free of charge by Certica Solutions and must be installed on whatever machine(s) students are using to take assessments, whether at home, at school, or in a lab environment.

To install LockDown Browser:

  1. Visit the LockDown Browser Installation File Download page for the installation files to download. 
  2. Download the appropriate file, based on whether you are a student and whether you use Windows® or MacOSTM or a district-managed Chromebook.
  3. Run the installation file and follow the on-screen instructions.
  4. At the end of the installation, click Finish.


  • You only need to install LockDown Browser one time on each device.
  • Students do not need to run LockDown Browser directly; it will start automatically when needed for taking an assessment.
  • Supported devices include Chromebooks (district-managed), Windows/PC and Mac; ipads and student-owned Chromebooks are not currently supported.

Step 2 - Consider Video Conferencing for Proctoring

Although LockDown Browser prohibits the use of other applications during an assessment, you may make an exception for video conferencing software for remote proctoring purposes. Supported video conferencing applications are: Zoom, GoToMeetingTM , or any video conferencing software that runs in a browser. These may be allowed to run in the background so that teachers can view students while they are taking an assessment. 

Once your district is set up to use video conferencing:

  • Students need to download and launch the video conferencing application before starting the test.
  • Students need to select all settings before starting the test. For example, they will need to turn on their video, unmute, etc.
  • Virtual backgrounds are not supported.
  • Video conferencing applications run in the background but without controls. 

Note: enCASE does not manage the video conferencing meeting invitations or links. Districts need to manage and distribute video-conferencing links to students either via email, LMS, or other messaging service, as they normally do outside of enCASE.

Step 3 - Contact Certica

Once you've installed LockDown Browser on the devices you will use for testing, please contact the HelpDesk. They will enable your district to have the option of using LockDown Browser. Additionally, if your district wants allow the use of video conference applications (as described in the section above), let the HelpDesk know.

Step 4 - Enable Benchmark Assessments

Provided your district has contacted us, and students or lab managers have installed LockDown Browser appropriately, administrators may require LockDown Browser for specific benchmark assessments.  

Assigning for Schools

During the benchmark scheduling process (as described in Scheduling CASE Benchmark Assessments) , an administrator assigns assessments to schools by making selections on the Assign Schools page. To require the LockDown Browser, check the box for it next to the appropriate school on the Assign Schools page.

Note: You may only enable LockDown Browser for benchmark assessments, not classroom/local assessments.

Viewing Classroom Schedules

When looking at benchmark assessment schedules for classrooms, you will see whether LockDown Browser is being required for that assessment at that school. It is read-only. 

Administrators may choose Assign Schools from the Assessments menu if they want to change the LockDown Browser requirement at the school level.

The Student Experience

When an assessment requires LockDown Browser, students will log into an assessment as described in the Student Experience article. After they click Take Assessment, they see a dialog box such as the following:

They should click Open LockDown Browser OEM.

LockDown Browser launches.

It will request that students close applications that are currently running, via dialog boxes such as the following:

Students may choose Close Process to close the identified application.

Note: LockDown Browser requires that most applications be closed before it opens. However, if your district allows for video conferencing, those applications will continue to run in the background. Browsers will also continue to run in the background.

Once LockDown Browser is running, the assessment appears:

The window is full-screen and the navigational controls for the browser are minimal.

At any time, the student may click Exit to close the LockDown Browser window.
