Tingtun Checker

What is the difference between the Tingtun Checker and other tools such as CynthiaSays or the (X)HTML Validator by the W3C?

Tools like the (X)HTML Validator by the W3C test the code for validity.
But accessibility is more than just valid code. That is why the W3C HTML tests are integrated into the Tingtun Checker together with further accessibility tests.

Compared to CynthiaSays and other tools, that check accessibility, there will be many similarities. But different approaches put the emphasis on different parts.

Please also note that formally, validation is not required for WCAG 2.0 conformance.

Can the Tingtun Checker find all barriers?

No, the Tingtun Checker can not find all barriers. It can only detect barriers which can be detected automatically. The checker currently covers 9 out of 38 success criteria from WCAG 2.0.

For a complete overview of barriers on your web site, a manual evaluation is required. However, a manual exhaustive evaluation of web accessibility is generally very labor intensive.

In addtion to identifying barriers, the Tingtun Checker also provides reports about parts of the web page that need further human judgment to confirm the accessibility. For instance test 2.4.6-2 reports problems with labels for form controls. If a label is defined the user of the checker is asked to verify that the label describes the purpose of the form control.

I get score 100% from the Tingtun Checker. Does this mean my web page is completely barrier free / accessible?

This may not be the case. No barriers detected by the Tingtun Checker (score 100%) only means there were no barriers detected using the automatic tests.

There may still exist barriers which the Tingtun Checker could not detect. For a verification that your web page is completely barrier free / accessible, manual tests performed by an accessibility expert are needed in addition.

Why is it that reliable and well linked sites like Google also fail several tests?

The accessibility of websites is not correlated with how known the website is, but with how it is implemented.

The Tingtun Checker uses 32 tests to evaluate the document automatically and you can get more information on the passed/to be verified/failed tests on the result page.

Why is the result from the eAccessibility checker different from other evaluations, such as the web site quality assessment made by the Agency for Public Management and eGovernment (Difi)?

The Tingtun Checker evaluates only one page. while Difi selects up to 3 pages that are representative of the complete web site.

Both the Difi and the eGovMon approaches have selected a subset of all possible indicators of web accessibility. There is some overlap, but the emphasis is put on different parts.

Only the accessibility component of the eGovernment quality assessment percentage score should be considered in the comparison because usability and content are not covered by the Tingtun Checker.

What can the Tingtun Checker be used for?

The Tingtun Checker automatically detects barriers the in your web page and gives you immediate feedback.
