text: I am sorry but giving a written test to high school students is no way to identify a security expert. They should just join 'Root This Box' once they get it rebuilt and they will find plenty of eager whitehats XD
  Understanding network security is more a mindset than a native "ability". It's very abstract and, in my opinion, testable.
  Sadly there will be plenty of kids who think it will be cool to 'play war' against similar outfits in other countries. They are to young to understand the difference between a Starcraft match and the death and misery that can be created by full out cyber-attack.
  @Skeptic Heretic, I don't doubt that some people might be identified who may have a future in the field. My comment was more about the density of useful results. When testing at random highschools they will find a very small number of people who actually have the minds and interest to be security experts in the future. There are other communities where that percentage would be much higher, and it makes MORE sense imo to test there, rather then at public schools. So I don't actually disagree with you, and probably worded my comment poorly in any case ;)
