Screen reader tests - January 2020


We’ve just released a new batch of screen reader test results. We started testing screen reader support for accessibility features in 2012. Since then we’ve run over 10,000 individual tests covering 54 browser and screen reader combinations.

New tests in this release cover:

  • NVDA 2019 with Chrome, Firefox and IE11
  • JAWS 2019 with Chrome, Firefox and IE11
  • VoiceOver with Safari on macOS 10.14 and iOS 12

This is the first release with tests results for Chrome. Chrome support for Windows screen readers is very good apart from the built-in PDF viewer.

Also new in this release are test results for PDF. PDF accessibility support is mixed - it’s good with VoiceOver on macOS and iOS with Safari, but poor with Firefox on Windows because it displays PDFs using PDF.js which doesn’t support tagged PDF yet.
