Cellphones & exams in the UK

Will this be happening in the US soon, as student per capita cellphone use approaches that of the UK? Across The Pond, "students can be marked down or even failed for just having a mobile phone with them during exams, whether they use them to cheat or not," CNET reports. The number of students penalized for cheating was up 27% last summer over the previous year, and possession of cellphones during exams accounted for about 25% of the penalizing, according to the UK's Qualifications and Curriculum Authority. Of course, phones possession wasn't the only issue – other offenses included "plagiarism, collusion or copying another candidate's work, typically in coursework done before a final exam" … "cheating or disruptive behavior during exams, writing obscenities on their exam papers, or failing to follow instructions." Still, the number of people penalized is relatively low: "less than one incident for every 1,500 exams taken."
