dominKnow | ONE: Accessibility Conformance Report (ACR) (VPAT)

As pioneers in standards-based publishing and web accessibility for the last 20 years, our commitment has a proven track record. We've been innovating with accessibility before it was "required" and when doing so was particularly challenging (e.g., Pre-WCAG 2). We made this decision because we felt and still feel that it was and is the right thing to do for the learning community. 

dominKnow, the developers of dominKnow | ONE, wants everyone to be able to use eLearning courseware created with dominKnow | ONE. That means, for example, end-users of the courseware can:

  • Use browser extensions and settings to change contrast levels, fonts, and font sizes
  • Zoom in up to 300% without the text spilling off the screen
  • Navigate the courseware using a keyboard alone
  • Navigate the courseware and input text by voice command using Dragon speech recognition software
  • Listen to all of the relevant content in the courseware using a screen reader (including the most recent versions of JAWS, NVDA, VoiceOver, and TalkBack)

General Guidelines

Avoid using the following interactions and content design treatments:

  • Text colors defined by the author that lack sufficient color contrast
  • Toggle controls and other stock objects that lack sufficient color contrast
  • Interactions that require use of a mouse such as drag-and-drop
  • Interactions that rely on visual cues such as interactive “try-it” modes of software simulations

Be aware of the unique features and capabilities of assistive technologies that may interpret the HTML produced by dominKnow | ONE differently:

  • JAWS 2023 announces mutually exclusive radio buttons inconsistently. Mutually exclusive means that when the user selects a radio button, any previously selected radio button in the same group becomes deselected, making it so only one can be selected.
  • Most assistive technologies do not allow navigation of Sequencing or Sorting interactions.
  • Menu status indicators do not programmatically indicate current, not visited, visited page states.
    • Note: Targeting release
  • Voice command using Dragon Desktop Professional 16 skips odd numbers on Slider interactions.

Resources for Authors

Authors using dominKnow | ONE to create accessible eLearning courseware can access relevant accessibility resources within the tool. dominKnow also offers training for authors on how to develop accessible courseware using the tool. For more information on the available resources, visit our Getting Started in dominKnow | ONE and WCAG Accessibility Resources.

Evaluation Process

In response to a commissioned request by dominKnow, this Accessibility Statement and associated Accessibility Audit Report were produced by Interactive Advantage Corporation (IAC). Testing was supported by IAC team members who are familiar with the dominKnow software and who teach classes on how to develop accessible courseware with the product. Testing was performed by qualified individuals who hold recognized accessibility testing certifications and who routinely use assistive technologies when testing web-based content. Code-based inspection was the primary means of testing with supplemental manual testing performed as appropriate. The principal tester was Mary Ann Richards, U.S. Department of Homeland Security Trusted Tester Certification #TT190900082.

WCAG 2.2 Report

Note: When reporting on conformance with the WCAG 2.2 Success Criteria, they are scoped for full pages, complete processes, and accessibility-supported ways of using technology as documented in the WCAG 2.0 Conformance Requirements.

Table 1: Success Criteria, Level A


CriteriaConformance LevelRemarks and Explanations
1.1.1 Non-text Content (Level A)Partially Supports

Most elements added to a page provide for the option to include Screen Reader and/or alt text. For elements that cannot have alt text assigned, authors can use text-based alternatives, such as Screen Reader text to communicate meaning.

Screen Reader text is a dominKnow feature that allows an author to add additional text-based context to an element which is rendered as an ARIA label in the published output.

Components of the following elements have non-text content but do not support or have limited support for the addition of alt text or other text alternatives such as Screen Reader text: Icons, Guide Me Simulation, Scenario images, Thermometers, Flip Set images, Flash Card images, Match Card images, Drag and Drop style questions, Hotspot questions, and Menu status indicators. Note: for many of these, alternative options exist – IE a flip set, use text instead of an image.

Guides to writing Alt Text


NOTE: Release will include enhancements for text alternatives for icons, flip sets, flash cards, match cards. It also will include status indicators for menus.

1.2.1 Audio-only and Video-only (Prerecorded) (Level A)Supports

Authors can add text-based alternatives for audio-only and video-only content.

For audio-only content, authors can add a transcript to the audio file itself or use text-based alternatives.

For video-only content, authors can provide a text description using text-based alternatives.

Working with Transcripts for Audio Files, Video Files and Pages >>

1.2.2 Captions (Prerecorded) (Level A)Supports

For captioning, authors can import closed caption files into video players.

System supported closed caption files include: SRT, VTT, and SBV.

Easy Closed Captioning (CC) File Upload for Videos with Multi-language Support >>

What is a Closed Caption File?

Guides and Tools for creating Closed Captions

1.2.3 Audio Description or Media Alternative (Prerecorded) (Level A)SupportsAuthors can provide a description of the visual content in videos as an alternate video file or provide access to a transcript with descriptions of visual aspects of the synchronized media on the same page or via a link.
1.3.1 Info and Relationships (Level A)


Partially Supports

Most elements are programmatically formatted to communicate informational relationships.

Interactions that need additional descriptive text include: Input Toggle, Learner Progress Radial Gauge, and Carousel.

Interactions that are simply not compliant because of inherent reliance on visual cues only: Sorting, Matching, Fill in the Blanks, and Sequencing interactions.

Release will include enhancements to carousels and form controls.

1.3.2 Meaningful Sequence (Level A)


Content built in dominKnow Flow follows a top-to-bottom, left-to-right reading order by default. 

Authors should be aware of breakpoints and how responsive flow drives reading order. The author can control the order of content presented by placing the elements in sequenced Rows, Groups, and Sections.

Content built with Claro uses layer order for flow/tab order. Authors should review their layer order to make sure content proceeds in the intended reading order.

Authors should limit inline Pulldowns and inline Fill-in-the-Blank questions to one answer, so the association between question text and answer choice is clear.

1.3.3 Sensory Characteristics  (Level A)SupportsAuthors can provide text-based descriptions for content that can otherwise only be understood by shape, size, visual location, orientation, or sound.
1.4.1 Use of Color (Level A)Supports

Authors should provide complementary alternatives to explain information when color is used to convey information or instructions. Use patterns, textures, or text labels to differentiate information. 

Some question interactions display correct/incorrect selections using color, such as Practice/Exam Multiple-Choice, Matching, and Sequencing questions and Question/Exercises Click the Word, Matching, and Sequencing. In these cases, authors should include text-based feedback that indicates the correct/incorrect selections.


Default colors for questions can be set with the Theme Designer.

1.4.2 Audio Control (Level A)Supports

Audio and video players include play/pause and mute controls by default.

Authors can enable a more extensive set of controls or build custom controls that offer greater control of media by the learner. 


Controlling audio files.

2.1.1 Keyboard (Level A)Partially Supports

Most elements in courses developed with dominKnow Flow support keyboard accessibility.

Exceptions include: Markers, Video Playlist, Image Hotspot, Guide Me Simulation Job Aid, Sorting, and Drag and Drop style interactions.

2.1.2 No Keyboard Trap (Level A)Supports

Content developed with native elements supports navigation of all content without keyboard traps.

For custom HTML Widgets, authors should provide learners with a way to utilize keyboard controls to exit the HTML Widget content.

2.1.4 Character Key Shortcuts (Level A 2.1 and 2.2)Supports

The built-in keyboard content controls meet this standard and are only active on focus.

Media elements have shortcut keys/interactions but are not active when those objects are not in focus.

2.2.1 Timing Adjustable (Level A)Supports

Authors can create actions/triggers that give the user the ability to manipulate or extend the time limit and reveal notifications based on the time limit.

Authors should avoid using system timer variables as actions/triggers cannot be set by the author to give the user the ability to manipulate or extend the time limit and reveal notifications based on the time limit.

2.2.2 Pause, Stop, Hide (Level A)Supports

Default media players provide pause and stop controls for media. Content produced in dominKnow Flow does not inherently include moving, blinking, scrolling, or auto-playing content natively.

If this media is included by the authors, they should provide the learner with custom pause, stop, or hide functions for moving, blinking, scrolling, or auto-updating content.

2.3.1 Three Flashes or Below Threshold (Level A)Supports

Content produced in dominKnow Flow does not inherently include anything that flashes or blinks more than three times a second.

When adding animations or videos, authors should refrain from using content that flashes or blinks more than three times a second.

Authors should select a WCAG accessible theme. These Themes are identified with a “WCAG” badge in the Theme Browser. These Themes include skip navigation controls by default.

2.4.2 Page Title (Level A)Supports

The course title will be automatically used as the page title that appears in the browser tab using the attribute.

Title refers to the content focus as a whole. To further enhance this capability, we are adding ARIA live regions in 7.4.5 enabling subtopics (pages etc.) to be announced.

2.4.3 Focus Order (Level A)Supports

Flow content follows a top-to-bottom, left-to-right focus order by default.

The author can control the order of content presented by placing the elements in sequenced Rows, Groups, and Sections.

Claro content follows a bottom-to-top layer order controlled by the author.
