Below is a list of the current assistive technology (AT) products and versions. SSB recommends the current version be used for testing with exceptions.


  • Generally SSB Recommends waiting a month from the initial release of many AT products before using that product for official testing.
  • SSB will defer to client requirements for AT versions upon request.
  • Some assistive technologies are bound to specific platforms such as iOS and VoiceOver and to some extend features in TalkBack with Android
    • Keep in mind that the version of a platform used by the general public may not be the same version used by most people with disabilities.
      • e.g. Android 4.4 may be more common to the general public than Android 5.x, however, Android 4.4 does not support switch control and has other accessibility limitations when TalkBack is running. Therefore it is very likely that users with disabilities will have Android 5.x
  • Platform versions and vendors can have an impact on accessibility
  • Specific device form factor can also play a part in accessibility or what is shown in the UI during test
    • iPad and iPad Air may have features such as split screen and app switchers that don't appear on phone
    • iPhone has vibrate and LED that do not appear on iPad
    • iPhone 6 and 6 plus have Reachability option

Note: Refer to the Assistive Technology Browser Combinations page for which browsers to use with which AT.

    • Most modern devices can be upgraded to the latest iOS version free of charge and thus SSB recommends testing with the latest iOS version
  • App of standard iOS on-screen keyboard will generally be used for testing of input with the on-screen keyboard (in addition to external keyboard).
  • Android 5.1.1
    • The latest version of Android (6.0, Marshmallow) has a very low adoption rate in the real world and thus SSB generally recommends testing one version back - see Android Developers' Dashboard
