I am a HLTA in a primary school, covering all classes from year 1 to year 5/6. So a different class each morning and afternoon. I have been in this school doing this job since September 2010. I go home if not in tears, close to them every night due to the unruly behaviour of the classes. They will not be quiet for me at all, I follow the behaviour policy to the letter and have observed lessons to get ideas, however all strategies that work for others do not have any effect for me. Today the class were really noisy, not listening to instructions and generally ignoring me, I tried clapping a rhythm, which they are supposed to copy and then be quiet - no effect. Another member of staff - a TA- walked in clapped and their was complete silence. As soon as she left the room back to noisy. I have raised concerns with my Head, who was supposed to observe me and offer suggestions, this has not happened yet, however not sure this would help as their behaviour would not be the same. I am in my second year of a foundation degree hoping to continue to a further year with QTS but am beginning to suspect that I have chosen the wrong career. Before this I worked for 5 years as a TA in a secondary school and never had a problem with respect and discipline. PLease help I will try anything!
