Accessibility tools can help you keep your website accessible.The Readability Test Tool
This tool allows you to check the complexity of your page and how readable it is. You can input a URL or the actual text to check how readable it is. The recommended scores are as follows:
Gunning Fog and Flesch-Kincaid Grade: between 6 and 8. These values are an estimate of the number of years of schooling that would be required to understand the webpage content.
Flesch Reading Ease: aim for a score of around 60 to 70. The higher the score, the easier your page is to understand.
This free web accessibility evaluation tool allows you to enter a URL, file or HTML code and show you whether there are any accessibility issues.
Colour Contrast Analyser
This free tool works in conjunction with the WCAG2 guidelines in colour contrast which the WC3 now recommend and we also strongly endorse and follow. It allows you to compare the foreground and the background of say a button with text, to check if there is enough contrast between the two colours so that the text is visible to all users.

Web Accessibility Toolbars for your Browser
There are various accessibility toolbars available, depending on what browser you are using:
Firefox: N-Abled Web Accessibility Toolbar - General text zoom and colour checker.
Web Developer Toolbar - This is the most recommended toolbar as you can turn off CSS to ensure that page content displays as it should and is read as it should by a screen reader.
Note: Text zoom can be tested by using ctrl and the '+' on your keyboard to zoom in. Likewise ctrl and '-' will zoom out, and ctrl and '0' will reset to original size.
Internet Explorer: Vision Australia's Web Accessibility Toolbar - Similar to the Web Developer Toolbar for Firefox.
Google Chrome: Web Developer Toolbar - Similar to the Web Developer Toolbar for Firefox.
Safari: Safari Developer tools - not completely designed for accessibility, however some features could be used to test accessibility.
