A teacher checks a school girl with a metal detector before she enters her mid-term examination, in a middle school in Nanjing, east China's Jiangsu Province, November 14, 2006. Metal detectors have been used since 2005 before the national college entrance examination in an effort to crack down on cheating. The use of detectors has come under criticism from parents and students in the area.
