A government study in Britain recommends Faraday cages for examination rooms. A Faraday cage is basically a metal-lined room that blocks all radio frequency signals. In other words, test takers won't be able to use their cellphones to text message friends for exam answers. The study also recommends scanners to detect MP3 players and other devices. It seems that some students are recording notes on their iPod and playing the content back during the exam.
