Yet our public schools are obsessively focused on standardized testing to the severe detriment of children with learning disabilities, children who are English as a second language learners and children who are low income.
Those kids commonly lose electives, are forced into after school tutoring and/or summer school, and held back grades, which is strongly correlated with dropping out. All as a punishment for low scores on standardized tests, no matter how hard they work.
Public school in the US is broken badly. If you want to keep it, you need to come up with some fixes and fast.
Sooner or later, no matter how loudly Weingarten shrieks, a real voucher program will be passed somewhere and when it works far bettervthsn the compulsary system voters everywhere will demand it.
