And last I checked, Brainbench scored rather universally poorly by Perl experts for their quizzes, and appears to resist outside review of their testing by such experts. Hence, it's not a valid certificate to the Perl community, or at least shouldn't be for clueful people.
If someone from Brainbench reads this and would like to challenge this, I would be happy to review your test for free. Otherwise, I shall continue to denounce your test as an unreliable indicator of Perl knowledge, as I have done frequently publicly in the past.
As for certification, it's already been said in this thread that the biggest benefactors are the test givers, with the biggest losers being the potential employees or contractors, and the employers fairing somewhere in between.
It's important to keep in mind that the only certification that will matter to people with clues is one that is blessed by Larry Wall himself.
And last I checked, he was still clueful enough to not bless any particular test. And I hope that continues to be his position.
