Not Confined to the U.S.
Cheating [Is] the System
From the article:
This year, 54 proctors from around China had been brought in to Zhongxiang with a mission: Prevent cheating. It was a reaction to the discovery last year that 99 students in that testing facility had turned in identical papers. Officials had decided that something needed to be done.
The proctors used metal detectors to find transmitters. Male and female students were frisked, and cell phones found in underwear were confiscated. During the test, patrols around the site uncovered groups trying to radio messages to students taking the test.
