Many would just quit, and among those who stayed what are the options ?
Get fired when the school is shutdown for under performing.
Fill in tests for students.
If we use programming as an example, the best tech manager on earth can’t get a bunch of random people to write production ready code in a month ( maybe JS, but not Rust).
Public schools can’t pick and choose students. Charters sorta can.
If I ran the school system I’d set up *paid* apprenticeship to job programs in high schools. Actually get these kids real careers. You SHOULD be able to afford an apartment with a high school degree.
