I can understand you very well.
I was very worried about public schools and, before moving to "the Far East" of Italy, I sent my kids to a private school close to the Swiss
border, where I lived.
Here the situation is a lot better, because our region has a special status, being it on the border and multi tongue, so we have a lot of autonomy, which helps make also public school much better than elsewhere.
You still have to cope with some unionised teachers, who think the school is there for them and not for the pupils, but it is acceptable.
