As input to the collection of extant publicly documented accessibility  
evaluation methodologies, here is a short description of BITV-Test:

BITV-Test (www.bitvtest.eu) is a German-language web application for  
website accessibility evaluation according to the German  
implementation of WCAG 2.0, BITV 2.0.
BITV-Test is based on WCAG 2.0 Level AA (with minor deviations such as  
the inclusion of AAA-Level SC "2.4.8 Position"). It provides a  
hands-on, tried and tested procedure for expert evaluation with  
references to tools (e.g., Web tool bars) and support for the  
interpretation of check results. Test steps also reference WCAG  
techniques and failures.

Here is a more detailed English description of BITV-Test:  

BITV-Test is available in three forms:
1. a page level self test (open to everyone after registration)
2. a design support tests with a single tester
3. a final (conformance) tests with two independent testers and a
    concluding arbitration process to resolve differences in both assessments.

Some more features of BITV-Test:

* The test procedure in form 2 and 3 is quality-controlled, e.g., the
   tester's page sample selection must be checked and approved by a member
   of the BITV-Test quality assurance team

* The test procedure is fully documented at http://testen.bitvtest2.de
   (a full English translation is under preparation)

* The web application generates a website test report as accessible PDF
   containing all checkpoint assessments and comments

* If desired by the client, the test report is published as HTML and
   then permanently available for independent verification. This is what a
   report looks like: http://testen.bitvtest2.de/index.php?a=ti&sid=2005

* BITV-Test uses a score (five grades between "fully conforming" and
   "fails to conform") for rating the accessibility of pages per checkpoint.
   The final score is expressed as "X points out of 100" (where 100 points
   would be a flawless site).

* BITV-Test does not separate WCAG Level A and AA. It does not offer,
   at the time being, separate conformance testing for WCAG on
   level A or level AAA
