Accessibility
Ensuring all learners succeed
Our mission is simple: to help people make progress in their lives through learning. We will only be successful when our educational materials are accessible to all users.
We’re committed to providing access to students with disabilities. Our commitment is woven into the fabric of our learning materials, development processes, innovation efforts, employee culture, and partnerships.
PDFs
Wherever possible we have provided a HTML version of PDFs on this site.
Layout
This site uses cascading style sheets for visual layout. Users can change the style sheets in their browsers to make viewing easier for their individual requirements. All pages on this site use structured semantic markup. This site uses only relative font sizes, compatible with the user-specified "text size" option in visual browsers. If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.
Colors and Contrast
As an aid to readability we have tried to ensure a good level of contrast between text and background colours. You may also browse the site using a 'High contrast Theme' or the 'Standard Theme'. This option is always available from the footer.
On certain browsers you can override our design and use your own preferred colour scheme. Instructions on how to change background and font colors for common web browsers appear below; for other setups you will need to consult your browser's help pages.
