Accessibility statement

This is the official accessibility statement for If you have any questions or comments, please contact us.

This policy applies only to Web pages on the AES Web site (i.e. URLs starting that make use of standard templates (i.e. pages that have the same structure, navigation and design as this one).

Standards compliance

As far as possible, we have tried to ensure that:

  1. All pages on this site should comply with all priority 1 & 2 and most priority 3 checkpoints of the W3C Web Content Accessibility Guidelines 1.0.
  2. All pages on this site are valid HTML5.
  3. All pages on this site use valid CSS.
  4. All pages on this site use structured, semantic markup. h1 tags are used for main titles, h2 tags for subtitles (and so on). For example, on this page, JAWS users can skip to the next section within the accessibility statement by pressing ALT+INSERT+3.


  1. All content images used in this site include descriptive alt attributes. Purely decorative graphics include null alt attributes.
  2. Complex images include longdesc attributes or inline descriptions to explain the significance of each image to non-visual readers.

Visual design

  1. This site uses cascading style sheets for visual layout. Tables have not been used for layout and are only used to present tabular data.
  2. This site uses only relative font sizes, compatible with the user-specified "text size" option in visual browsers.
  3. If your browser or browsing device does not support stylesheets at all, the content of each page should still be readable.


Some functionality on the web site is best experienced using a browser that has JavaScript enabled (for example, the online games). However, you can still access the content in a different form if you do not have JavaScript enabled.

Access Keys

The AES site does not use access keys due to the potential conflict with browsers or other user agent's (particularly assistive technology) shortcut keys.
