Accessibility criteria

SEMO is committed to ensuring that this website achieves "Double-A" conformance with the World Wide Web Consortium's (W3C) Web Content Accessibility Guidelines (WCAG) 2.0. This means that every page should comply relevant Level AA (Double A) Success Criteria as specified in the WCAG 2.0 guidelines.

We are committed to ensuring that any new additions to the website will achieve "Level AA" conformance to the World Wide Web Consortium's (W3C) Web Content Accessibility Guidelines (WCAG) 2.0. The most recent web accessibility audit took place during May 2010.

Accessibility features

In addition to achieving WCAG 2.0 Double A compliance we have provided a variety of accessibility features.

Skip link

We have provided a skip link to people using JAWS or other screen readers to jump straight down to the page content.

Changing text size

All fonts are scalable - most browsers provide a means to specify default base text-size. You can change your text size using your browser. Please refer to your browser help to learn how to re-size text or use zoom controls.

Separating content, structure and presentation

The site uses Cascading Style Sheets (CSS) for layout and visual formatting. If your browser does not support CSS or your wish to turn it off then all pages are still easily readable and actionable. All content (with the exception of the table issue identified below) have appropriate structural markup.

High contrast style

We have provided controls on this site to enlarge text size and access a high contrast version of the website.

Known compliance issues

Please be aware of the following known compliance issues. These may affect your experience of the website. If you have any difficulty accessing information please contact us.

PDF, Word and Excel format documents

The site makes use of certain non-W3C technologies such as Portable Document Format (PDF), Microsoft Word (DOC, DOCX) and Microsoft Excel (XLs, XLSX). Certain documents on this site are available in these formats only. This requires you to download and install 3rd party software.

Market dashboard

Certain information (namely the Value of Market table and Trading Day Max and Min Daily Price) may be difficult to access if you are using JAWS or a similar screen reader.

Data tables

Certain tables of information on the website lack correctly marked up table headings. Unfortunately these tables are generated automatically using Microsoft Reporting Services. Their output cannot be modified. Most of these tables are large, with a simple structure. They may be difficult to access if you are using JAWS or a similar screen reader.
