Who's going to teach them? We can't even hire enough teachers for the shitfestival that education is now, how do you find more teachers?

Once you get those teachers who are skilled at driving advanced classes, would you require them also work in the poor performing classes?

That's a conditions trap, now that good teacher is dealing with the administration and trauma burden of the low performing class making it complex for them to perform in the advanced class.

Would you make them specialists? That's an equity and human resources management nightmare. Whid want to work in a class of hard students when classes of dreamy well behaved engaged kids is a possibility

Do we keep it the same and continue to systemically disadvantage everyone?

There are no easy answers. The entire education system needs to be invented and rebuilt from the ground up.
