Is LockDown Browser accessible to those with disabilities?
Posted by Respondus Support

LockDown Browser meets all web content accessibility guidelines, as documented in our Voluntary Product Accessibility Template (VPAT). LockDown Browser also works with many assistive technologies, with details listed below.

Screen Readers

  • Windows: The Windows version of LockDown Browser is tested and works with NVDA, JAWS, and MS-Windows Narrator. LockDown Browser's functions and security remain the same when these screen readers are used.
  • Mac: The Mac and iPad versions of LockDown Browser are tested and work with VoiceOver (the standard screen reader that comes with the Mac OS). LockDown Browser's functions and security remain the same when VoiceOver is used. More about VoiceOver

This is not an exhaustive list of screen readers that work with LockDown Browser, but are the ones we test and verify. LockDown Browser does not block screen readers, and conforms to WCAG 2.0, so screen readers not listed here will likely work too.

Text-to-Speech (also known as “read aloud” or “literacy” software)

  • Texthelp Read&Write (Windows): LockDown Browser has a custom integration with Read&Write. When a student is using LockDown Browser, a “lockdown mode” setting will be applied to the Read&Write toolbar, preventing certain features from being used during an exam (e.g., web searches). The reader and Screen Masking functions remain available to students during the exam. More about Read&Write
  • ReadSpeaker webReader for the LMS (Windows and Mac): When WebReader is embedded within a learning system, it will work seamlessly with LockDown Browser with some security limitations (e.g., copy/paste and MP3 downloads are disabled). The reading, masking, and text enlarging functions remain available to students during an exam.
  • ReadSpeaker TextAid (Windows): The “bookmarklet” version of TextAid works with LockDown Browser on Windows computers.
  • Speech (Mac): Speech will work with LockDown Browser, however it does not read multiple choice or true/false answer choices correctly with all LMS integrations. This issue and a potential fix is being investigated by Respondus.
  • Others: Because many text to speech (TTS) applications include advanced functionality that would be considered exploits within LockDown Browser, portions of these programs cannot run on top of a LockDown Browser window. These programs are not blocked, however some functionality may be limited while using LockDown Browser (e.g., Natural Reader).

Speech-to-Text (also known as “Voice-to-Text,” or “dictation” software)

  • Windows Speech Recognition: Works with LockDown Browser, with some limitations. More about Windows Speech Recognition

  • Mac Voice Control: Works with LockDown Browser, with some limitations. More about Mac Voice Control

  • Nuance Dragon: Dragon is not blocked by LockDown Browser during an exam, but some functionality may be limited. Users have reported that adjusting the settings to turn off the dictation box will allow Dragon to work with LockDown Browser.


  • Zoom Text: Zoom Text works during a LockDown Browser exam. Students may encounter issues during exams that also require Respondus Monitor.
