I am a new cover supervisor with less than a year experience, and I started a full time post at a mainstream secondary last week. Previously I did some supply part time. It has just hit me how hard this job is. I am not a qualified teacher. Most of the over cover supervisors are, and they have all got a lot more experience than myself. The others seem to keep control of classes easily, yet about 50% of the time I can not even get the children to be quiet when I am speaking to them, trying to teach or explain the instructions of the task. For example, today I was completely ignored when I was standing at the front, at the top of my voice trying to get the children to be quiet. I was even counting down from three, out loud but was completely ignored. I had to resort to writing the task on the board rather than explaining it. I am already questioning whether or not this job is suitable for me. I am on maternity cover until July but I am starting to think that I will be dismissed if my teaching quality does not improve. Twice since starting this job I have had to send for help from another member of staff.
