Whether parents, as invigilators, should avoid suspicion in their children's postgraduate entrance examination is worth discussing. First of all, it is necessary to clarify the purpose and responsibility of parents as invigilators. The main duty of invigilators is to ensure that the examination is fair, just and smooth and to prevent cheating. Therefore, parents, as invigilators, must have certain educational experience and management ability to ensure the smooth progress of the exam.

However, parents who are invigilators may face some difficulties. On the one hand, there is kinship between parents and candidates, which may lead to parents' partiality or unfairness in dealing with exam questions. On the other hand, parents may lack professional invigilation knowledge and skills, and cannot effectively deal with various problems in the exam.

In order to avoid these problems, parents as invigilators should take some measures to avoid suspicion. First of all, parents should maintain an objective and fair attitude, treat all candidates equally, and do not take sides. Secondly, parents should receive relevant training and guidance to improve their invigilating ability and quality. In addition, parents should also work closely with other invigilators to maintain the fairness and justice of the examination.

In short, parents, as invigilators, should avoid suspicion in their children's postgraduate entrance examination. By maintaining an objective and fair attitude, receiving training and guidance, and cooperating with other invigilators, parents can effectively perform their invigilating duties and ensure the fairness, impartiality and smooth progress of the examination. This is not only conducive to children's test scores, but also conducive to maintaining the fairness and justice of education.
