LockDown Browser

Note for Students: The Respondus LockDown Browser (LDB) software in SacCT was changed to begin automatic updates starting on May 30, 2014. If you are prompted to update your version of LockDown Browser you MUST update it or you cannot use the software to take a test.

For assistance in updating the LockDown Browser software, please see Respondus LockDown Browser: Run Updates and Take an Exam (PDF).


Respondus LockDown Browser™ is a customized browser that increases the security of online testing in SacCT. It prevents students from printing, copying, going to another website, or accessing other applications during an assessment. If a SacCT assessment requires that Respondus LockDown Browser be used, the assessment won't be accessible with a standard Web browser.

Respondus LockDown Browser should only be used for taking assessments in SacCT. It should not be used in other areas of SacCT or to visit other websites.

Getting Started

  1. An instructor must first set a test for use with the Respondus LockDown Browser. Refer to LockDown Browser Faculty Quick Start Guide for SacCT (PDF).
  2. Instructors should add a Web Link to their course that points to the Installation page for students, so students know where to go to get the software.
  3. Follow the Installation instructions to download and install the correct version of Respondus LockDown Browser for your computer.
  4. Review the Taking an Assessment steps when you are ready to take an online quiz or exam.
  5. Once you are in the LockDown Browser window and have logged into SacCT, prior to launching the quiz or exam, use the "Help Center" button that appears at the top center of browser, to run a system check prior to taking the exam. Please see the Help Center for LockDown Browser information page for detailed steps.

To avoid last-minute problems, it’s strongly recommended that Respondus LockDown Browser be installed and tested well before students are expected to use it for an exam. If students are installing Respondus LockDown Browser to their own computers, we suggest that you create a sample quiz where the sole purpose is to confirm whether students have successfully installed the Respondus LockDown Browser and understand how to use it for taking a test.

Handouts & Tutorials


Accessibility for Students with Disabilities

Due to the limited use of the Alt, Ctrl, Function, and Option keys while Respondus LockDown Browser is running, which limits the functionality of assistive technologies used by students with disabilities, we recommend you NOT require students with disabilities to use Respondus LockDown Browser for assessments.  If a student with a disability requiring the use of an assistive technology to access content online is enrolled in your course, you should establish a plan to provide the student an equal alternate form of access to take assessments, such as taking the assessment in the Testing Center and/or creating an alternate assessment that does not have the LockDown Browser restriction.

To learn more about what you can do to make your instructional materials accessible, contact the Instructional Materials Specialist at 278-2847 and visit the Instructional Materials Accessibility Checklist webpage.
