I have had a problem with the small number of perennially unsafe students in our workshops. One, for example, was regularly unsafe during year 9. He was statemented for behaviour, his statement including the line, "has little or no awareness of risk". He had permanent TA support in class, but this didn't prevent him from deliberately smashing his own work up with a hammer, running out of the classroom, then pelting the window with snowballs whilst being told by his TA, who'd chased him, to stop. One snowball hit a window close to someone who was working on a Hegna saw, making them jump. I filled in all the usual paperwork, and suggested to the SLT that he was permanently excluded from the subject. I even filled in a separate risk assessment for him. Within this I proposed he would not be allowed to take D&T in year 10. Amazingly, he appeared on my RM lists for year 10. I expressed concern about this, pointing to my risk assessment. I was told that by the Deputy Head that I would have to manage the situation! Not suprisingly, he, within two weeks after the start of term, had smashed his work up with a 1 metre steel ruler, which he swung overhead. It narrowly missed his TA's head. I managed to have him removed from RM for 1 week only. When he returned, after a good week or so, he started a fight, culminating in him grabbing a sharpened piece of acrylic which he saw nearby, and trying to stab another lad in the neck with it. I had to physically intervene. This time I again appealed for a permanent ban from the subject. The SLT removed him from RM for a week. I ended up going off sick - with stress - about the time he returned to RM lessons. He has since then been permamently excluded from the school. I feel very let down by my SLT, and having now been off school for about a year - with a break when I did a phased return - am seriously considering jacking in teaching. I used to be a project manager in heavy manufacturing industry. In even the most traditional companies, such as mine, if anyone was seen in the factory without the correct PPA on they would be given a verbal warning, then a written one. One more infringement, and they would be sacked. I really feel this sort of regime should be implemented in schools, even for simple things like safety goggles, otherwise a) our young people won't be able to cope with getting a practical job, and b) our teachers will increasingly be squeezed between getting results and 'keeping naughty children busy' when they can't sit still in a desk-based subject. Don't getme wrong, I love teaching, and will do anything to help them enrich their lives through extra things like doing the Greenpower electric car racing, and the Toyota Technology Challenge. My lesson observations generally come back as Good, and as HOD I feel I am doing a good job. Results are pretty good. However, this tension between coping with the naughty ones that I'm not allowed to exclude, the needs of the curriculum, and the never-ending pressure of the coloured charts that tell me so-and-so is underperforming by one grade compared to a target based upon their desk-based '3 Rs' work from a few years ago, is getting to me!
