Technical information about this website’s accessibility

The University of Sheffield is committed to making its websites accessible, in accordance with the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018.

Compliance status: This website is partially compliant with the Web Content Accessibility Guidelines version 2.2 AA standard, due to the non-compliances listed below.

Non-accessible content

The content listed below is non-accessible for the following reasons:

  • Images and Charts: Some complex data visualisations do not have sufficient text alternatives to explain the trends shown in the graphs. This fails WCAG 2.2 success criterion 1.1.1 (Non-text Content). We are working to provide plain-text data summaries alongside key visualisations.
