Details

Rule ID Image 1
Definition Each img element must specify an alt attribute or equivalent markup that either defines a text alternative or identifies the image as being used for decoration, spacing or some other stylistic purpose.
Purpose
  • A text alternative for an image, usually specified with an alt attribute, provides a summary of the purpose of the image for people with visual impairments, enabling them to understand the content or purpose of the image on the page.
  • An image with a text alternative that is an empty string or that has role="presentation" is ignored by assistive technologies. Such markup indicates that the image is being used for decoration, spacing or other stylistic purposes rather than meaningful content.
WCAG Success Criteria

Techniques
  • A text alternative should summarize the purpose of an image as succinctly as possible (preferably with no more than 100 characters).
  • The alt attribute is the preferred and most commonly used way to provide a text alternative for img and area elements.
  • The aria-labelledby attribute can be used to provide a text alternative when an image can be described using text already associated with the image, or for elements with role="img".
  • The aria-label attribute should only be used to provide a text alternative in the special case when an element has a role="img" attribute. Use the alt attribute for img and area elements.
  • The title attribute will be used by assistive technologies to provide a text alternative if no other specification technique is found.
  • Use the attributes alt="", role="presentation" or include the image as a CSS background-image to identify it as being used purely for stylistic or decorative purposes and one that should be ignored by people using assistive technologies.

Implementation Score Definitions

  • The implementation score is based on the rule results across all pages and ranges from 0 to 100.
  • '-' means there were no rule results for that group (e.g. rules were not applicable).
  • The following messages give a general idea of the overall implementation of the rules for a website.
Abbrev Score Status Description
C 100 Complete Complete means all rules have passed. There were either no manual checks or all manual checks have been resolved.
R 0 Required Manual Checks
  • Manual checks are required to verify accessibility. Markup has been identified that needs to be reviewed to determine if accessibility requirements have been met.
  • Start with the website and page level manual checks since they affect website and page navigation and identification of content and then start on the element level manual checks.
AC
AC-R
95-99 Almost Complete
  • Almost Complete means that you seem to understand the accessibility requirements of the rules, and are close to fully implementing their requirements on all pages within the website.
  • "-R" means there are required Manual Checks. Markup has been identified that needs to be reviewed to determine if accessibility requirements have been met.
PI
PI-R
50-94 Partial Implementation
  • Partial Implementation means that you may understand at least some of the accessibility requirements.
  • "-R" means there are required Manual Checks. Markup has been identified that needs to be reviewed to determine if accessibility requirements have been met.
  • Please re-read the accessibility requirement and review the techniques before trying to improve the accessibility.
NI
NI-R
0-50 Not Implemented
  • Incomplete means that you do not understand the accessibility requirements of the rules or did not consider accessibility in the design of the website.
  • "-R" means there are required Manual Checks. Markup has been identified that needs to be reviewed to determine if accessibility requirements have been met.
  • Please read the accessibility requirements and review the techniques before trying to improve the accessibility.
na - Not Applicable No markup was found that identifed a known or possible accessibility issue.

Note: Future versions of FAE will allow you to mark manual checks as, pass, fail or not applicable.

Implementation Score Computation

Implementation Score = P / (P + F + MC)

Each variable represents the number of element level results for a particular rule, where:

  • P = elements that passed
  • F = elements that failed
  • MC = elements that require a manual check

The score ranges in value from 0 to 100, that is from no implementation to all accessibility requirements met. In the future, FAE will allow you to change manual checks to pass, fail or not applicable, and will recompute the Implementation Score based on the updated manual checking results.

Note: When a manual check is changed to not applicable that element result is removed from the implementation score computation.

Implementation Score Combinations

Implementation scores are rule-based and are computed for the following combinations:

Pages Rules Calculation
1 1 Element level results determine the implementation score for a rule on a specific page.
1 All The implementation score for a page is the average of all implementation scores for all rules on the page, with all rules being equally weighted.
All 1 The implementation score for a rule across all the pages in a website is based on the aggregation of all element results for the rule across all pages.
All All The implementation score for a website is the average of the website rule implementation scores.

Example Rule Implementation Scores on Individual Page

Description Pass Fail Manual Check Implementation Score
A rule with scope of element, like "Image must have alt text". 8 2 0 80
A rule with scope of page like "Page must have main landmark". 0 1 0 0
A rule with scope of element with elment results of pass, fail and manual checks that may occur for the color contrast rule. 134 29 37 67

Example Rule Implementation Score for All Pages in a Website

This is a hypothetical example for a website

Page results for Rule X Pass Fail Manual Check Implementation Score
Page 1 element results for rule X. 23 12 4 59
Page 2 element results for rule X. 12 4 0 75
Page 3 element results for rule X. 45 0 0 100
Website element results for Rule X 80 16 4 80
