The National Centre for Excellence in the Teaching of Mathematics (NCETM) is committed to accessibility. We want our website to be accessible to everyone. If you experience any difficulties in accessing our website, or have trouble using any aspect of the site, please contact us.
The National Centre is actively working to increase the accessibility and usability of our website, and in doing so adheres to many of the available standards and guidelines to ensure websites are accessible.
We seek to follow W3C Content Accessibility Guidelines to ensure it is accessible to all regardless of ability or disability. We are moving towards conforming to level Double A of the World Wide Web Consortium (W3C) web content accessibility guidelines 2.0. These guidelines explain how to make web content more accessible to people with disabilities, and to make the web more user-friendly for everyone.
The website has been built using XHTML 1.0 Transitional and uses CSS 2. It displays properly in current browsers including Internet Explorer, Mozilla Firefox, Google Chrome, Safari and Konqueror. The website is also known to work on smart phones; the i-Phone (Safari) and Windows Mobile 6.
- All pages on the website include a consistent set of global navigation links.
- All pages including the homepage have a “breadcrumb” trail. The head of this trail is the home page of the current major section of the site.
- All pages on the website include a search box.
- Meaningful alternative text (known as 'alt text') has been supplied with images on our website. Where the visitor cannot see the image, they will still be able to read the alt text. Purely decorative graphics include empty ALT attributes. There may be occasions with historical content where this may not apply.
- All links have been written to make sense when taken out of context. Many browsers (such as JAWS, Home Page Reader, Lynx, and Opera) can extract the list of links on a page and allow the visitor to browse the list, separately from the page. There may be occasions with historical content where this may not apply.
- Most links can be followed in any browser, even if scripting is turned off.
Structure and Content
- HTML heading tags are used to convey document structure. Across most of the site H1 tags are used for main titles, H2 tags for subtitles. This aids in searching for content and helps screen readers to distinguish content by navigating headings using keystrokes. Other browsers (for example, Opera) or assistive technologies may provide different or additional functionality based on headings that appear in the page
- The website aims to use plain English where possible.
- Pages are made easy to read, avoiding long sentences and paragraphs.
- Common types of font have been used to ensure everyone can read the pages.
- Users can alter the text size using the AAA link at the top of each page.
- Style sheets are used to control layout and presentation which aids in ensuring consistency across different browsers and platforms.

The BBC's My Web, My Way portal provides advice and help to people who may benefit from making changes to their browser, operating system or computer to be able to view and navigate websites more easily.
PDF and Word documents
Documents on the website are usually in either Adobe Acrobat or Microsoft Word format. Those in Adobe Acrobat will require Adobe Acrobat to be installed on your computer. Adobe Acrobat Reader can be downloaded for free. Most computers already have the correct software to open these document formats. If you do not have Adobe Acrobat Reader (for viewing and reading PDFs), you can download the free software from the Adobe website. Documents in Microsoft Word format will require the visitor to have a version of Microsoft Word.
All audio is provided in Flash format with the additional ability to download the source file in MP3 format. We recommend that visitors use the most latest version of Flash player. If the user does not have the most recent version, they will be prompted to download the most recent version.
All video is provided in Flash format with additional ability to download the source file in flash and avi format. We recommend that visitors use the most latest version of Flash player. If the user does not have the most recent version, they will be signposted to download the most recent version.
The website uses some Flash to provide additional ways of interacting with the content. Where appropriate the website provides a HTML version of the Flash content. We recommend that visitors use the most latest version of Flash player. If the user does not have the recent version, they will be signposted to download the most recent version.
The NCETM strives to adhere to the accepted guidelines and standards for accessibility and usability, although it is not always possible to do so in all areas of the website.
We are continually seeking solutions that will bring all areas of the site up to the same level of overall web accessibility. If you experience any difficulty in access in any content on the website, please contact us.
