I'm a retired secondary school teacher. This has been going on for years - it's just easier to report now. Having said that, my experience in supply over the past few years has shown me that discipline is becoming even worse.
It used to be that the violent episodes could not be relayed to the region by a classroom teacher or Principal Teacher - only a member of the SLT could do it.
By the time I retired from my PTC post in 2018, we could report acts of violence directly to the region on an online form. (The heidies - at least in our area - could still get off with marking them as 'dealt with', but at least the notification went through to the region.)
Prior to that, I twice had a desk thrown at me (by different boys) and I can assure you that that info wasn't passed to the region.
The time that a teenage boy punched me in the stomach, the local police 'lost the statements'. That was before the SNP government told the courts to tread lightly with offenders under the age of 21, but even then - about 20 years ago - the police were avoiding writing up the paperwork on those under the age of 16.
Around the same time, a colleague was punched by a pupil in front of the entire school. The only reason the region knew about it was that the boy's parents complained to the Director of Education because the teacher had had the temerity to block the second punch.
Another pupil who wrecked my classroom one time had zero consequences - typical of their school career. This was more than 20 years ago. I'm not aware that any of their violent acts were recorded at region level.
The said pupil was recently found not guilty of culpable homicide, though there's no doubt that they were involved in an illegal activity and had been violent.
Even further back, as a young teacher I reported a pupil who wrote a fantasy in which he raped one of his teachers. I was laughed at by the boy's Guidance Teacher. No, it wasn't passed on.
That former pupil is currently in Carstairs and unlikely to leave.
Both Labour and SNP governments have been guilty of sweeping pupil violence under the carpet. However, the SNP has exacerbated by the problem by making it known that there are now few consequences if any for those under the age of 25 and by pushing the 'restorative conversation/trauma informed' narrative even more.
I finally came off the GTC register this year. I miss some aspects of teaching, but I don't miss dealing with the violence. The last time that I was in a school, I was hurt twice in one week - once stopping a fight, once stopping an assault.
The same week, a young female teacher was hurt whilst minding her business in a corridor. In another department, a pregnant PSA was hit.
