<p>Son's school does have this. Since the graduating class has only 40 students, it's fairly easy to tell who is who. Perhaps because it is such a small school (and everyone already knows everyone's business, I'm afraid), no one is complaining....at least, not yet.</p>
<p>If we had to wait for a sampling of 5 people per school, I'm afraid we might be waiting 5-8 years for the system to be functional at all. My son has found the information useful.</p>
