thePriority Basic (free version) and thePriorityPremium(paid version) are Themes built for screen reader users but should also be accessible to other disabilities as well as those without.
As much as a site can be Web Content Accessibility Guidelines (WCAG) 2.0 compliant we’ve strived to make it as accessile as possible but make no assurances that it will be perfect given that Plugins or other addons may not also follow WCAG 2.0.
thePriority is a simple Accessible and Responsive Theme with most of the default options that come with many WordPress Themes, custom headers, backgrounds etc, whereas thePriorityPremium has a comprehensive Theme Options area that allow you to make changes to the look without having any developer skills, for more details visit Developers Page.
This site is a mixture of the Basic and Premium versions for more details on what each has to offer visit the Developers Page.
