You may want to continue to where they wrote that they stopped doing restorative justice when the pandemic started an they ran out of money. What you quote creates the impression that restorative justice failed, rather than what actually happened which is that there wasn’t the money.
I mean, they can do what other schools do - just kick out any kid they think is a problem. That will of course include any kid who is bullied and responds, any kid whck teachers don’t like, etc, etc, etc. Fact is that the way that schools have been punishing students has not worked. I mean it my have had classes that were quieter, but students weren’t actually learning.
Maybe restorative justice would have worked had they actually tried it.
If something isn’t working, you can always depend on the higher administration of a school district to replace it with something worse.
