<p>My dear, just because I only pointed you to one study doesn’t mean only one study exists. </p>
<p>Here’s another one, that looked at the differences in performance between children offered a private school scholarship who accepted and didn’t accept the scholarship:</p>

<p>Or this one analyzing Boston and New York “exam schools”:</p>

<p>Here’s a nice quote from the Cullen/Jacob/Levitt paper:</p>

<p>There are, BTW, exceptions to these results. The studies do show that children from minority groups in extremely underperforming schools do show benefit from moving up to better schools. So the current available best evidence suggests that there is a threshold of quality that students need to achieve (at least minority students), but that once that threshold is crossed moving up to more elite schools does not have a significant impact.</p>
<p>I provide this information with no hope that facts or research will influence your already-formed opinion, but rather for others who may read this thread.</p>
