Common standards are good I feel. The problem is that when they are measured by testing and the results are reported etc kids get taught only what is in the test. That has obvious problems.

Also the whole point of having teachers is they can adjust and re-explain in a way that works for each kid. This doesn't work with a script (i thought you had teachers'unions?) or if the teacher is rigid and unsympathetic.

Like i said on another thread if you are going to give the teachers a script and not let them deviate from it you don't need trained teachers. It is hugely insulting to them to suggest they use such a script and i am not surprised if the ones that can afford it are leaving.
