I don't recall all the details, but a few years ago I had a similar experience with the Brainbench Perl exam and as a result of my list of complaints (with corrections) was invited to serve as a reviewer for a revision of the exam. Several corrections were made to the newly revised exam as a result of my reviews, but Brainbench were not interested in focusing on more advanced topics at the time. I vaguely recall having the impression that Brainbench had determined that customers were only interested in verifying applicants' knowledge of Perl for very basic tasks, and that other languages were more appropriate for real application development. Unfortunate.
