I recently went into a school for the first time having been called by the agency in the morning. I haven't been driving very long and had a scary drive in so arrived a little flustered. When I arrived at my first class a woman in the classroom opposite said to ask her if I needed help - I think she was a cover supervisor. The first class contained a group of boys who refused to stop using mobiles and playing music. I asked the cover supervisor what the procedure was and she said that they were a very difficult class. She had a word with them but they were rude so she rang for support. A member of SMT came in for about 5 minutes and had a word and after that they were fine. When I got home I found that the person who dealt with supply had rung the agency 10 minutes after the end of this first lesson to complain that I'd looked nervous when I arrived, had a weak handshake and had had to ask for help from SMT. I had no problems with any other classes. I even had the last class in silence doing a test. What annoys me even more is that there was no work set for the lesson after a break and I couldn't find anyone to help, there were no exercise books to give me an idea what they were working on and only a few text books which were foundation GCSE (it was top set year 9) There was noone around to assist so I had to choose an exercise quickly from the GCSE book and I even managed to keep that class on task.
