PATNA — About 600 high school students in eastern India have been expelled for cheating on pressure-packed 10th grade examinations this week, education authorities said Friday. The incident has received widespread attention after Indian television footage showed parents and friends of students scaling the outer walls of school buildings to pass cheat sheets to students inside taking exams. Teachers and state education department officials supervising the examination caught hundreds of students who had smuggled in text books or scraps of paper for cheating. “It's virtually impossible to conduct fair examinations without the cooperation of parents,” said P.K. Shahi, Bihar's education minister. He said it was not possible to monitor the 6 million parents and others who accompany the students to the examination centers. State authorities posted police at all schools where examinations were being held, “but we can't use force to drive away the parents,” he said. — AP
