Evaluating Your Website
A frequently asked question is, “What constitutes a ‘red’ rating? Is there a nuance between ‘not perfect’ and ‘definitely inadequate’?”
The answer is that Tufts requires conformance to WCAG AA standards.
A final question is, “How can I check if my website conforms to these standards?”
Below, there’s a link to the evaluation tool Tufts uses, a 5 minute quick check you can perform, a quick reference of the complete standards, and common tools to test with.
Here at Tufts, we use SiteImprove to evaluate our websites. SiteImprove checks your site against all WCAG requirements and flags all issues, issuing regular reports. If you have access, you can log in to SiteImprove here.
5 Minute Quick Check:
If you have five minutes, here is a quick check you can do to look for immediate and absolute red flags on your website:
- Here is a 1 page checklist with WCAG A standards that websites at Tufts historically have failed to meet. Be sure your website addresses all of these.
- Turn off images in your browser (make sure image placeholders are turned on). Is there an alt-text for each image?
- Try navigating your website with just a keyboard. Can you get to all the pages? Can you fill in and submit the forms? Is it easy to navigate in a logical order – when tabbing through a form, do you go down the fields in order or does it jump around?
- Try to change the standard font colors and styles in your browser. Does your website change, or have you locked it to a single font and style?
- Try to increase the browser’s font size (in Firefox, View > Zoom > Increase). Can you increase it to 200%?
Complete List of Requirements
Here is the official quick reference of WCAG 2.1 standards. It’s split into categories with examples for an easy look at a topic. You can filter by “A” and “AA”.
