I joined a security mailing list some time ago, recently they got to talking about what the ‘best’ certification to get for security training is. A certification to be a professional hacker? Who knew there was such a thing? One of the most notable ones they mentioned was OFCP (Offensive Security Certification). I took a look at their website, there are a couple good demos on there and the price to get certified appears reasonable enough. Apparently passing the test is difficult with “90% of people failing the first time”, or so says one of the folks on the mailing list.

EDIT:
Here are a couple more sites they shared that look interesting:
Hacker High School
HackBloc
