Article: 169 junior 1 students at No. 35 Middle School of Shenyang took their first noteacher exam. After the teacher handed out the exam paper, he left the room and never came back. A student collected the papers when the exam ended. "That test was not only a test of knowledge, but also a test of moral . We wanted to show students how important honesty is," said Cai Wenguo, the school's headmaster. The school says no cheating happened in the test.

"I was happy and excited during the exam because my teachers trusted me," said Lang Yudan, a 13yearold girl in Class 11. "Schools must trust students a lot not to use invigilators .

I would get higher marks without them in the room because I would feel more relaxed," Liu Qingxi said. "I think it's very important to have invigilators in exams.
