<p>Xiggi, a lot of schools have teacher’s unions and other things well in place that allow seniority to be rewarded in ways like choice. Trying to change any of things makes extracting teeth a breeze. </p>
<p>When I lived in the midwest, when a new elementary school was built, there was a mass exodus from the other schools in the district by the most senior teachers as they wanted the newer facilities which also served a more well to do group. Not much anyone could do about it. Making changes in the way public schools are run is a terribly slow process. </p>
<p>The fact of the matter is that MOST teachers want the higher achieving students. Given any choice, that is where they will go.</p>
