If it helps, most of the poor teachers weed themselves out of the profession within the first 5 years.

Personally I think the biggest obstacle to assessing teachers' performance is their union.
Yes, many of the poor teachers do weed themselves out but some are also protected by their union. It is very very hard to dismiss a poor teacher once they have achieved tenure. Quite often, the problem teacher in one school is simply passed on to another school.
And to counteract that, especially during times of recession or cutbacks to education, school boards simply do not grant tenure, choosing instead to hire teachers on temporary contracts.
And in the long term, that is not good for education either because if good teachers are only offered temporary contracts, after awhile, they too will move on.
