As my name implies, I know a thing or two about the process. It's messed up.It's a BIG thing right now in public education for schools not to do any real disciplining to the students. Mostly for legal reasons, of course. I would totally understand your frustration, because honestly the school that I work at would probably tell a parent the same thing, "We can't do anything unless there's proof". Here's what I would do, as a parent and public school teacher, meet with the teacher (did you say you already did that?). Ask them what YOUR kid's behavior is like in class. I hate to tell you this, but kids lie. Or kids give themselves a reason to be bullied. I know as a teacher, about 90% of my "bullying incidents" is because kids stick their nose in places where they don't belong, insult or talk to the kids that they shouldn't be talking to. And then, cry, because they are "bullied" when they shouldn't have even been putting themselves in that situation to begin with. What I mean is, YOUR kid sits across from the room from the kid who's bullying him, and HE'S the one who is constantly walking over to the other side of the room to start shit. Trust me, this happens way more than you think. 9 times out of 10, it's kids looking for trouble. I have rarely, rarely, seen incidents where kids are provokingly being bullied, by another kid approaching them and starting shit. It usually goes the other way around.... Reading your posts however, it does sound like your kid is just being bullied straight-up. If I had a parent come to me and tell me that their kid is being bullied, although I have never seen it, I would like the parent to request me to move my student somewhere else in the room (I'm assuming it's happening with someone sitting beside him). And ask the teacher to keep an extra set of eyes on the kid supposedly doing the bullying. In summary:1. Talk to the teacher to find out what your kid's behavior is like in the room. Possibly your kid is the one getting himself in trouble.2. Ask teacher to move your kid somewhere else in the room and to monitor his behavior, or the supposed bully. ... I don't think any teacher will say no to either of those requests. I will say though, as a teacher, I've had parents say "My kid is getting bullied" and a lot of times I want to reply: "Your kid is loud-mouth obnoxious dipshit, all the kids hate him. If I were a student, I would bully his ass too."Not saying this is what's happening in your case, but it wouldn't hurt to find out.
