What is WCAG 2.0?
WCAG 2.0 (Web Content Accessibility Guidelines) are a set of guidelines used to make web content more accessible to people with disabilities. These involve a wide range of disabilities, including visual, auditory, physical, and cognitive.
Is Coassemble WCAG 2.0 compliant?
Coassemble provides a platform that allows our users to create WCAG compliant courses for learners, however, it is important to note that there are a few things you must do when creating your content to ensure these requirements are met. These include:
- Ensure images have alternative text that can be read by screen readers
- Ensure you have a color scheme that allows for good contrast
- Ensure you're using templates that are appropriate for all learners
Alternative text for images
Alternative text, often referred to as 'Alt text', is used to provide a textual alternative to an image. This allows screen readers to read the description of images to visually impaired learners.
How to add alternate text in Coassemble?
All Lesson templates in Coassemble provide you with a way to add alternative text to an image. Anytime you add an image, you'll be provided with an input box for adding alt text. Simply add your description and click save.
Choosing an appropriate color scheme
If your company requires WCAG 2.0 compliance, it is important that you choose a colour scheme for lessons that meets specific requirements.
To meet WCAG level AA, you are required to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. There are a number of tools you can use to check the correct contrast of your foreground (font) color, and background color. A great resource for checking contrast can be found on the WebAIM website.
Changing the color scheme in Coassemble
From the customize screen you can adjust the color scheme of student-facing content by changing the background color of each template type. Coassemble uses a function that automatically chooses the correct contrast (either black or white text) for the chosen background color. It is important to note, that although this is the case, it is still possible to choose colors that don't contrast well with either black or white text so head over to the WebAIM website to check your colors meet the correct standards.
Choosing accessible templates
To meet the needs of a whole range of users in the Coassemble platform, there are a few templates that won't meet accessibility standards because they require the learner to have normal vision for completion. If you do want to meet WCAG 2.0 standards, it is important that you do not use the following templates:
- Drag and drop challenge, checkpoint, and quiz question
- Drag multiple checkpoint, and quiz template
- Match sequence checkpoint, and quiz template
- Dial challenge
- Spot the mistake challenge
- Correct category challenge
- Labelling challenge
- Branching Scenario Template
The templates with the magenta cross should not be used if needing to be WCAG compliant:
