Accessibility checklist for web writers
This checklist is based on the Web Content Accessibility Guidelines 2.0. It focuses on day-to-day web content issues that web writers control. It doesn't include extra checks for PDF or Word documents.
The checklist is divided into 4 topics: written content, structure and formatting, navigation, and images. Some of the guidelines have a wider scope than implied here, but the focus is on the work web writers do.
|1.3.3 Sensory characteristics||A||No instructions rely only on shape, size, screen location, orientation, sound or colour. A text label is also included.
|3.1.2 Language of parts||AA||Foreign language words or phrases have the appropriate foreign language tag.
|3.1.3 Unusual words||AAA||Jargon, idioms and special terms are defined (or avoided if possible).
|3.1.4 Abbreviations||AAA||Abbreviations and acronyms are defined (or avoided if possible).
|3.1.5 Reading level||AAA||Content scores below grade 10 in a readability test, after you’ve removed names and titles. If it does not, an alternative version or supplementary content (images, animations, video, audio) is provided.
|3.1.6 Pronunciation||AAA||A pronunciation is provided for heteronyms unless the context makes their meaning clear.
Structure and formatting
|1.3.1 Info and relationships||A||Headings, lists, tables, quotations and emphasised text are styled using the appropriate tag. Tags are not used to style text that is not a heading, list or quotation.
|2.4.6 Headings and labels||AA||Headings and labels are meaningful. They explain or describe the content that follows.
|2.4.10 Section headings||AAA||Each main part of the content is labelled with a heading.
|2.4.2 Page titled||A||Pages have meaningful titles that help users identify the page in search results and the browser tabs, history and bookmarks.|
|2.4.4 and 2.4.9 Link purpose (in context and link only)||A, AAA||Links clearly identify their purpose, preferably without relying on nearby content.|
|3.2.5 Change on request||AAA||Links generally do not open in new windows. When they do, a warning is included within the link text.|
|1.1.1 Non-text content||A||Images have an appropriate blank, short or long text alternative that effectively communicates the information or role played by the image.|
|1.4.1 Use of colour||A||No information is communicated only by colour. Text labels or patterns supplement colour.|
|1.4.3 and 1.4.6 Contrast (minimum and enhanced)||AA, AAA||Text and data in images use a colour that provides sufficient contrast from the background colour.|
|1.4.5 and 1.4.9 Images of text (no exception)||AA, AAA||Text is not presented as an image (except where decorative or part of logos, diagrams, maps, graphs, historical artefacts).|
|2.3.1 and 2.3.2 Three flashes (or below threshold)||A, AAA||Images do not flash more than 3 times in any one-second period.|
|3.2.4 Consistent identification||AA||Icons and their text alternatives are used consistently across all pages.|
Note: the guidelines are called ‘success criteria’ in the Web Content Accessibility Guidelines 2.0.
