Accessibility guidelines

In any work you do or research you carry out into accessibility, you’re likely to come across references to guidelines or web standards for accessibility which you should be bearing in mind or adhering to.

What are these, and how can you make sure you’re compliant?

• WCAG 2.0: The Web Content Accessibility Guidelines, published by W3C, are the most notable and comprehensive set of web accessibility guidelines. Some countries, including Canada, Australia and the EU, have a legal requirement for websites to meet WCAG guidelines. The WCAG 2.0 checklist can help in making sure that your website meets all of the requirements, and is a useful reference point.
• BS 8878: The British Standard 8878 is an accessibility code of practice designed to help web developers, project managers and production teams develop accessible products. It’s not free, but Access 8878 is a great free, plain-English guide to the standard.

Accessibility ‘spot check’ tools

There’s a wide range of automated tools available online that will help you quickly check specific elements of your website for accessibility. Handy though these tools may be, they can often be very literal in interpreting issues, without taking into account the full context of the site.

In general you should only use them for a quick, surface-level check, not as a substitute for proper accessibility testing or an audit – more on that in the next section.

• WAVE web accessibility evaluation tool: This tool will detect potential accessibility issues across your site as a whole, as well as highlighting the areas where it does well.
• WebAIM quick reference: testing web content for accessibility: A quick reference list of checklists, tools and simple tests you can carry out yourself.

• SortSite Desktop: A downloadable website testing tool that will check your site for issues such as compliance with W3C standards, accessibility and usability red flags.

Accessibility audit or accessibility testing? How to choose the right option

As I mentioned in the previous section, if you want to give your website a thorough, real-world check for accessibility compliance, you need to go further than just testing with automated tools.

The two options available to you are an accessibility audit with an expert consultant, or accessibility testing with disabled users. If you’re stuck on which one is right for you, below are some handy guides to consult.

While it comes down quite firmly on the side of auditing, it’s up-front about the advantages and disadvantages of both, and so is worth a read.
