The HTML and XML code of some website pages will not validate against the appropriate W3C specification. This fails WCAG 2.1 success criteria 4.1.1 (parsing). We are in the process of evaluating any invalid code on the website and will look to resolve all invalid code instances (where possible) as soon as possible. The validation errors should not cause any or substantial problems for the majority of users, but if you find the site is not accessible to you, please use the feedback option provided within this statement to let us know.
Within the experiment booking pages, some elements are not fully accessible with screen reader software. For example, we are aware that some form entry fields do not have meaningful labels for screen readers. This fails WCAG 2.1 success criteria 3.3.2 (labels or instructions). The booking pages are undergoing a redevelopment and this issue will be addressed as part of that development.
