Tweet about Accessibility Tester Services
I offer a variety of different Accessibility Testing services, but whichever of these you choose, it will be customised to meet the exact requirements of your website: No two websites are the same, audiences and the sites purpose differ, and so logically so too should the exact nature of the accessibility testing performed on your website.
I strongly recommend, in the first instance that a Preliminary Accessibility Review of your websites accessibility is made; Depending on the results of this it may then be appropriate to conduct full Accessibility Audit (conformance) testing.
I do not usually recommend an accessibility Audit (conformance testing), if the preliminary accessibility review reveals little chance of the website meeting level A or level AA WCAG accessibility test criteria. In such a case it may be preferred for the site to be checked by your design team to ensure it is 'up to scratch' before then returning back to me for accessibility Conformance testing.
Conformance testing, or Auditing will check your websites accessibility against the WCAG guidelines, and if the site passes these accessibility checks it can display its level of Accessibility conformance for all website visitors to see.
As part of Accessibility Conformance testing and preliminary Accessibility testing protocols I conduct a certain amount of 'user Accessibility testing' of the site. However, some clients may wish to consider full accessibility User Testing once a site has passed accessibility conformance testing.
For the majority of sites conformance accessibility testing, (with the user accessibility testing conducted as part of this), will provide a very good level of accessibility. However, conformance accessibility testing alone cannot ensure a site is accessible with users in the real world, who may have complex, multiple disabilities. In such a case accessibility User Testing may be required.
Preliminary Web Accessibility Testing looks at several issues that affect basic accessibility of web-sites. Some investigation of the underlying HTML/CSS code, combined with limited user accessibility testing on a selection of pages from the entirety of the site.
The full conformance accessibility testing (below) will typically include a brief preliminary review of accessibility; this may form the basis for concentrating attentions on those parts identified as areas of concern. Read more on my methodology for conducting preliminary web accessibility testing on the Preliminary Accessibility Review page.
As a blind screen-reader user with over a decades experience with JAWS and other screen readers, I conduct an in-depth user accessibility testing protocol tailored to your specific website. Additionally, I will test the website using a text only screen reader/web-browser, such as Thunder/WebIE. Identifying common tasks a user may perform on your web-site, then assessing the ease with which these can be accomplished with JAWS.
This method cannot highlight all accessibility issues, but can very quickly demonstrate if certain areas are problematic to some of the most important accessibility guidelines.
Full conformance accessibility testing of web-sites to the WCAG 1.0 or WCAG 2.0 guidelines. Utilising a combination of automated tools and detailed manual checking of the HTML and CSS code of the web-site.
A typical full Accessibility Assessment will consist of preliminary examination of accessibility, user accessibility testing with the JAWS screen-reader and full conformance testing to either WCAG 1.0, or 2.0 guidelines.
From this array of detailed testing, an accessibility report will be produced, outlining the level of conformance of the web-site, suggestions (if appropriate) on how the web-site's accessibility can be improved, and detailed results and protocols of the testing procedures.
With both Accessibility conformance testing and user accessibility testing I always include testing for Internet Explorer 8, Internet Explorer 7, Firefox and at least one text only browser. Can also include other browsers on request.
Where possible please contact me via the E-Mail address on my Contact page the cost of accessibility testing any given website will depend on the type of testing, the size of the web-site and its complexity, and ultimately on how long the testing procedures take.
