I think the 'goal' is perfection, however that may be defined in 'their' twisted little minds. Zero tolerance and harsh punishment is the means to that end.
I know an 11 year boy whose mother received a 'warning' note from school. Good kid, never in trouble, but he has had 3 tardies all year and is AT RISK of being referred to their Friday night detention program is he acquires 2 more tardies by the time school is out, next month.
600+ opportunites to be tardy, and 5 wins him a seat in the 'program'?
Several time this boy has received a 'zero' for work that wasn't turned in on time. Work was in his binder, failed to leave it at the end of class. Not a problem in any other class. Only the one where the teacher is a hard ass with black and white policies- "because that's what will be expected of him in high school".
Every year expectation increases. Kids are peddling as fast as they can to keep up with the unrealistic demands placed upon them. Any wonder they become frustrated/ hopeless? Seek relief from the constant barrage of mind numbing commands, and say fuck it?
And if they can't peddle fast enough, they are AT RISK of being warehoused with other square pegs who aren't cutting it in the failed system.
