Consider Home-Schooling...

I don't think there's any evidence to show such a relationship.

Bad teachers come from the same place that bad plumbers , bad policemen, bad architects and bad X comes from - society at large.

And society at large is also the place where good teachers, plumbers , policemen, architects and X comes from.

Developing the will to enforce higher standards for teachers et al is the problem. Today's prevailing attitude seems to be to 'let the other guy do it, I'm too busy'; so nothing changes. Getting involved is what's needed.

get the parents back on the job - ban both working at the same time - haul them into court when their kids misbehave - bring back extended families so kids are not isolated on large estates - so they grow up [before school] with half a dozen adult role models and learn there is more than one way of being right.....

ok tongue in cheek up to a point - but yes get involved - at the right level
