> But there is a lot more discipline

I think that would solve a huge number of issues. Teachers and admins seem to have no ability to kick repeated problem students out. My wife works as a para professional sub at our local elementary school. Twice this week a special needs girl was having a meltdown in a hallway and they essentially had to "quarantine" it until she calmed down. Students and teachers had to take other hallways to get where they needed to go. These children have educational needs that public schools cannot provide, but the burden largely falls onto them as an incredibly expensive (to the tax payer) babysitting service. Get them and the slowest students out of the general pipeline. They have been clogging it up and holding everyone back far too long.

And no. I don't have an adequate solution to handle the bottom X% of students who are beyond help from the general system. I just know the system can't function effectively with them in it. There are all sorts of other systemic issues I've seen through her experiences. But this is a major one which impacts all of the students. Classes cannot move at the pace of the slowest and / or most disruptive student. The slowest students need to be left behind for others to thrive. If they cannot reach the already low minimum standards, they cannot advance in grades. If they cannot behave to the low minimum expectations, their parents need to find other accommodations.
