Accessibility known issues

Issues with video, images and audio

Video

  • A few videos posted on our website don't have captions. All those videos were published before the 23rd September 2020 and thus don't fall under accessibility requirements

Images 

  • Some images do not have a meaningful text alternative, so people using a screen reader cannot access the information. This fails WCAG 2.1 success criterion 1.1.1. 

We are working to ensure that all images have a meaningful text alternative. Purely decorative images will have blank alt text and infographics and charts will have a link to a full description of the content.

  • Some images include text as part of the image, so people using a screen reader cannot access the information. This fails the WCAG 2.1 success criterion 1.4.5.

We are working to ensure that all images containing text with a suitable text alternative to include the image text. 

Issue with navigation, structure, links and keyboard operability 

Navigation: 

  • Not all page titles are unique and indicate the page’s topic or purpose, which can result in people with cognitive disabilities being unable to quickly orientate themselves within the site and identify the purpose of the page without interpreting its entire contents. This fails the WCAG 2.1 success criterion 2.4.2.

We are working to ensure that all page titles are unique, clear and descriptive.

  • Header rows in tables are sometimes necessary for users to understand the content of each cell, in relation between the cell and the header row. Such tables without a header row are less accessible to people using assistive technology. This fails the WCAG 2.1 success criterion 1.3.1.   

All tables are in the process of being checked and if necessary will have a table header row included. 

Structure: 

  • Not all headings are hierarchical, making the site more difficult for users of assistive technology such as screen readers to access. This fails the WCAG 2.1 success criterion 1.3.1.  

We are working to fix pages containing this issue.   

  • Heading have on occasion been used to highlight information rather than for headings, making the site more difficult for users of assistive technology to use. This fails the WCAG 2.1 success criteria 1.3.1 and 2.4.6.

All text that uses a heading to highlight information but does not serve as a heading will be fixed

Links: 

  • Some links do not use text that is meaningful out of context, which can result in users of screen readers not being able to understand the link without reading the surrounding text and users of speech recognition software being less able to target links accurately using voice commands. This fails the WCAG 2.1 success criterion 2.4.4.

All links are in the process of being reviewed and fixed.

  • The colour of the link text does not meet the minimum contrast requirements against the background. This can limit the site’s accessibility for people with low vision, poor eyesight or colour blindness. This fails the WCAG 2.1 success criterion on 1.4.3.

We are working with our developers to fix the link text colour and increase the contrast.

Keyboard operability: 

  • Carousels do not have obvious controls for users to stop the auto-rotate, which can cause people with cognitive disability that affect focus and concentration to be distracted making the site less accessible. This fails the WCAG 2.1 success criterion 2.2.2.   

We are working with our developers to implement fixes for these keyboard operability issues.
 

  • Some menus, links, buttons, and other controls cannot be operated using the keyboard alone, which can cause problems for people who are blind, have low vision and/or hand tremors. This fails WCAG 2.1 success criterion 2.1.1.   

We are working with our developers to implement fixes for these keyboard operability issues. 

Issues with contrast, use of colour and visual characteristics  

  • Some elements have low contrast levels (e.g. links), which can result in text being difficult to read, especially for people with low vision, poor eyesight or colour blindness. This fails the WCAG 2.1 success criteria 1.4.3.

We are working with our developers to implement a fix for this issue.

  • Some pages use colour as the sole way to convey important information, which means that users who cannot see colour are unable to perceive the information. This fails WCAG 2.1 success criterion 1.4.1.

All pages are in the process of being reviewed and fixed.

  • Some pages use visual characteristics (shape, size, colour or location) to communicate instructions, which means that users who are unable to see or recognise information communicated using sensory characteristics are unable to perceive that information. This fails WCAG 2.1 success criterion 1.3.3.

All pages are in the process of being reviewed and fixed.

Issues with language and content 

  • Where the language of all or part of a page isn’t English this isn’t defined in the html, which can result in screen readers being unable to correctly read the text. This fails WCAG 2.1 success criterion 3.1.1 and 3.1.2. 
     
  • The line height, spacing between paragraphs and letter and word spacing cannot be changed without loss of content or functionality. This means that people with low vision, dyslexia or cognitive disabilities may struggle to read the text, or lose content or functionality. This fails WCAG 2.1 success criterion 1.4.12.  
     
  • When using mobile or tablet devices, it may not be possible to dismiss or interact with some extra content (i.e. pop-up images) without moving focus, losing functionality, or it disappearing. This may cause problems for disabled or sight impaired users as pop-up content may be accidentally triggered or pop-up content may not stay on the screen. This fails WCAG 2.1 success criterion 1.4.13. 
     
  • Third-party content might interrupt a page viewed without style sheets.
     

We are working with our developers to implement fixes for these issues.  

Issues with documents, including Word files, PowerPoints, PDFs 

  • Many of the documents (Word and PDF) on this site do not meet accessibility standards, which could result in them not being fully accessible to users of screen readers. 

Documents that are essential to the service we provide will be either converted to HTML pages or replaced with accessible versions. 

Issues with Content Management System (CMS) 

  • The CMS code is being checked to ensure that it meets the robust accessibility criteria 4.1.1, 4.1.2 & 4.1.3. 

This will be done as part of an accessibility upgrade of the Drupal Content Management System.

Disproportionate burden

  • As resources, we have posted recordings of conferences, seminars and presentations as videos, as well as accompanying PDFs of seminar slides. It would be a disproportionate burden to create transcripts or captions for conference, seminar or presentation recordings, and to ensure that all accompanying PDF slides are accessible.
     
  • As resources, we have posted Presentation summary drawings that were designed during a conference. It would be a disproportionate burden to add full descriptions of the content.
