WCAG Conformance Declaration

This document is a WCAG Conformance statement, modeled after the Voluntary Product Accessibility Statement ( VPAT), but using the Web Content Accessibility Guidelines (WCAG) as conformance criteria. Due to the fact that Section 508 is grossly out-of-date and that the eventual Refresh will incorporate WCAG by reference, the format below is more useful than the existing VPAT format.

WCAG 2.0 Level A

Guideline 1.1 Text Alternatives

Success Criteria Supporting features Remarks and Explanations
1.1.1 Non-Text Content All non-text content that is presented to the user has a text alternative that serves the equivalent purpose, except for the situations listed below. (Level A)
  • Controls, Input: If non-text content is a control or accepts user input, then it has a name that describes its purpose. (Refer to Guideline 4.1 for additional requirements for controls and content that accepts user input.)
  • Time-Based Media: If non-text content is time-based media, then text alternatives at least provide descriptive identification of the non-text content. (Refer to Guideline 1.2 for additional requirements for media.)
  • Test: If non-text content is a test or exercise that would be invalid if presented in text, then text alternatives at least provide descriptive identification of the non-text content.
  • Sensory: If non-text content is primarily intended to create a specific sensory experience, then text alternatives at least provide descriptive identification of the non-text content.
  • CAPTCHA: If the purpose of non-text content is to confirm that content is being accessed by a person rather than a computer, then text alternatives that identify and describe the purpose of the non-text content are provided, and alternative forms of CAPTCHA using output modes for different types of sensory perception are provided to accommodate different disabilities.
  • Decoration, Formatting, Invisible: If non-text content is pure decoration, is used only for visual formatting, or is not presented to users, then it is implemented in a way that it can be ignored by assistive technology.

Guideline 1.3 Adaptable

Success Criteria Supporting features Remarks and Explanations
1.3.1 Information and Relationships Information, structure, and relationships conveyed through presentation can be programmatically determined or are available in text. (Level A) Supports Tenon uses proper markup for its content. Tenon structures all content with headings. All list-like content is constructed as lists. All tables have proper headers and the relationships between header cells and data cells is indicated. Tenon makes use of ARIA-landmark roles and HTML5 sectioning elements to structure each page.
1.3.2 Meaningful Sequence When the sequence in which content is presented affects its meaning, a correct reading sequence can be programmatically determined. (Level A) Supports The reading sequence of Tenon's user interface is programmatically determinable. The visual flow of Tenon's UI matches the programmatic flow.
1.3.3 Sensory Characteristics Instructions provided for understanding and operating content do not rely solely on sensory characteristics of components such as shape, size, visual location, orientation, or sound. (Level A) Note: For requirements related to color, refer to Guideline 1.4. Supports None of the instructions for Tenon rely solely on sensory characteristics.

Guideline 1.4 Distinguishable

Success Criteria Supporting features Remarks and Explanations
1.4.1 Use of Color Color is not used as the only visual means of conveying information, indicating an action, prompting a response, or distinguishing a visual element. (Level A) Supports Tenon does not use color as the only means of conveying information, indicating an action, prompting a response, or distinguishing a visual element. Any information presented through the use of color is also conveyed in text or other programmatically distinguishable method.

(Level A) Not applicable Tenon does not provide content with audio

Guideline 2.1 Keyboard Accessible

Success Criteria Supporting features Remarks and Explanations
2.1.1 Keyboard All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes, except where the underlying function requires input that depends on the path of the user's movement and not just the endpoints. (Level A) Supports with exceptions All core functionality is keyboard accessible. Tenon's dashboard contains two charts that provide tooltips on hover. Those tooltips are not available via keyboard.
2.1.2 No Keyboard Trap If keyboard focus can be moved to a component of the page using a keyboard interface, then focus can be moved away from that component using only a keyboard interface, and, if it requires more than unmodified arrow or tab keys or other standard exit methods, the user is advised of the method for moving focus away. (Level A) Supports with exceptions When logged-in, users are able to use a "Test Now" feature that is located at the top of the page. Users can enter a URL or HTML source to be tested. When tabbing through Tenon's UI, users can tab forward through the "Test Now", however activating Shift+Tab to go back to prior elements is not possible. Users are not necessarily trapped, as they can tab forward, but this is an inconvenience.

Guideline 2.2 Enough Time

Success Criteria Supporting features Remarks and Explanations
2.2.1 Timing Adjustable For each time limit that is set by the content, at least one of the following is true: (Level A)
  • Turn off: The user is allowed to turn off the time limit before encountering it; or
  • Adjust: The user is allowed to adjust the time limit before encountering it over a wide range that is at least ten times the length of the default setting; or
  • Extend: The user is warned before time expires and given at least 20 seconds to extend the time limit with a simple action (for example, "press the space bar"), and the user is allowed to extend the time limit at least ten times; or
  • Real-time Exception: The time limit is a required part of a real-time event (for example, an auction), and no alternative to the time limit is possible; or
  • Essential Exception: The time limit is essential and extending it would invalidate the activity; or
  • 20 Hour Exception: The time limit is longer than 20 hours.
Supports No functionality within Tenon requires a timed response. However, users' sessions will time out with no opportunity to extend. The length of time before a user will be "timed out" can be adjusted in their settings and can be set to longer than 20 hours.
2.2.2 Pause, Stop, Hide For moving, blinking, scrolling, or auto-updating information, all of the following are true: (Level A)
  • Moving, blinking, scrolling: For any moving, blinking or scrolling information that (1) starts automatically, (2) lasts more than five seconds, and (3) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it unless the movement, blinking, or scrolling is part of an activity where it is essential; and
  • Auto-updating: For any auto-updating information that (1) starts automatically and (2) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it or to control the frequency of the update unless the auto-updating is part of an activity where it is essential.
Supports with exceptions No content on Tenon blinks or scrolls. Content on 3 pages automatically updates once per minute and that update cannot be stopped: The Dashboard, History, and Projects.

Guideline 2.3 Seizures

Success Criteria Supporting features Remarks and Explanations
2.3.1 Three flashes or below Web pages do not contain anything that flashes more than three times in any one second period, or the flash is below the general flash and red flash thresholds. (Level A) Supports No content within Tenon flashes more than 3 times.

Guideline 2.4 Navigable

Success Criteria Supporting features Remarks and Explanations
2.4.1 Bypass Blocks A mechanism is available to bypass blocks of content that are repeated on multiple Web pages. (Level A) Supports Tenon uses ARIA landmarks to allow users to skip between sections of the page. Tenon also provides a "skip link" on all screens.
2.4.2 Page Titled Web pages have titles that describe topic or purpose. (Level A) Supports with exceptions Tenon provides a title on each page. In the majority of cases the page titles are good. Some titles are generic, especially when content arrives via AJAX, such as test results.
2.4.3 Focus Order If a Web page can be navigated sequentially and the navigation sequences affect meaning or operation, focusable components receive focus in an order that preserves meaning and operability. (Level A) Supports All focus order within Tenon makes sense and visual focus order matches programmatic focus order.
2.4.4 Link Purpose in context The purpose of each link can be determined from the link text alone or from the link text together with its programmatically determined link context, except where the purpose of the link would be ambiguous to users in general. (Level A) Supports All links make sense within context

Guideline 3.1 Readable

Success Criteria Supporting features Remarks and Explanations

3.3.2 Labels or Instructions Labels or instructions are provided when content requires user input. (Level A) Supports with exceptions The State/ Province field shown to visitors outside the US on the checkout screen does not have a label. All other form fields are labelled properly and clearly.

Guideline 4.1 Compatible

Success Criteria Supporting features Remarks and Explanations
4.1.1 Parsing In content implemented using markup languages, elements have complete start and end tags, elements are nested according to their specifications, elements do not contain duplicate attributes, and any IDs are unique, except where the specifications allow these features. (Level A) Supports Tenon's markup is well formed and fully conforms to the requirements of this success criteria.
4.1.2 Name, Role, Value For all user interface components (including but not limited to: form elements, links and components generated by scripts), the name and role can be programmatically determined; states, properties, and values that can be set by the user can be programmatically set; and notification of changes to these items is available to user agents, including assistive technologies. (Level A) Supports Tenon fully conforms to the requirements of this success criteria, except as noted elsewhere (i.e. 1.1.1, 3.3.2).

1.4.4 Resize Text Except for captions and images of text, text can be resized without assistive technology up to 200 percent without loss of content or functionality. (Level AA) Supports with exceptions Tenon utilizes responsive design and responds well to text-only resize up to 200%. However, the menu on the left side uses overflow:hidden, which causes some menu options to disappear when text is resized to 200%.
1.4.5 Images of Text If the technologies being used can achieve the visual presentation, text is used to convey information rather than images of text except for the following: (Level AA)
  • Customizable: The image of text can be visually customized to the user's requirements;
