The 'accessibility strip' at the very top of each page on the NAS website enables you to:
Change the background colour
This feature is designed primarily for people with dyslexia. The colourways were chosen by what used to be the Disability Rights Commision (now the Equality and Human Rights Commission) following laboratory-based tests to establish the most useful colourways for people with dyslexia. They gave kind permission for us to replicate the same service on this website. We have deliberately chosen to implement the colour change on the main body of text only as it tends to be large blocks of text on screen that give rise to problems.
Enlarge the font
By clicking on the AAA at the top of each page you can change the font size. If you feel this does not cater to your needs, the Firefox browser offers excellent text size enhancement options.
