Question 107: Appropriate testing

At our most recent testing we had a first degree black belt testing for his second degree. He is a teenager (16 years old) and a good student, but he has had attitude problems in the past. At the testing , after he had already said he was not going to promote the student, our instructor took me and two other large, male, adult students aside and ask us to use very heavy contact with this student to attempt to make him loose control during sparring. I did as I was asked and thankfully, nobody was injured! The student did not lose control, but he sparred 8 rounds of heavy contact, and then when he didn’t fall apart, he sparred 3 rounds of two on one, also with heavy contact. Our current instructor is also 17 years old, is friends with this student at school, and has a problems with the instructor/student relationship. I’m not an angry dog, to be set upon whom ever my instructor wants to send a message to. When is heavy contact appropriate during testing and to what lengths is it appropriate to test a student’s self-control?
