So I got a lot of aggravation from a hostile parent recently and I promised myself I wouldn't let what happened happen again. Briefly, the problem was that I came in with the expectation that the parent simply needed some clarification on their kids grades/performance in class but ended up getting attacked. In the process of defending myself (with no intervention from the admin) I became more and more aggravated and defensive. By the end of it I felt victimized. Instead of the meeting being about how the kid can improve it became about my perceived deficiencies. Now I realize the best approach is to swoop in and set the terms of the conference from the very beginning. I have a parent who has requested a conference for a kid who got in trouble for walking out of class and the parent is not telling me what they want to talk about and I have no idea what kind of attitude I'm dealing with, so I'm going to just assume that they will want to hassle me. This time, I want to go in in a professional and friendly, but firm manner, stating that the purpose of the meeting will be to clarify my expectations and discuss how the kid can better meet them. Unfortunately, not knowing what these parents thinking/perception of things is, it's hard for me to do that. Any suggestions?
