Welcome to my classroom!
Many of our site templates already meet the right level of accessibility quality. In fact, templates from our template library have completed an accessibility audit quite recently. Any issues to which such a template might have contributed should be resolved. For sites making use of a template library template, we'd suggest that in Site Manager, in Configure Templates, you click the "Update" button to get these latest changes--they should bring no visible changes to your site, but could have a positive impact on accessibility. For sites using a custom template, we highly recommend you consider our maintenance package. This would allow us to evaluate your custom template and proactively support any accessibility and performance issues on an annual basis. That’s not to say that without such a maintenance package, we wouldn’t be able to address specific issues that you might raise that appear tied to the template.
