Why not untie the teachers hands and let them do their job, have control of the class room, learn from the past, other countries do this and look at their results.  Having classes that include those who are mentally challenge should stop, it is not fair to anyone.  Dress code, teachers should dress as teachers, dress as being in charge, not dress like the students.  Students should dress properly and look presentable, there is nothing wrong with looking good.  Schools teachers are quitting, not able to teach, not able to control the class rooms, the students have taken over, this must stop.  Remember these are children, they must learn manners, respect for others, if the parents will not teach this, then the teachers have to teach.  Look at it this way, would you hire someone who will do as please, not listen, you would not, so why would you allow what is happening in the schools to day to continue.  Put the Teachers in Charge, get the class rooms under control. Goals accomplished.
