<p>What’s the difference between first quintile and second quintile in the college matriculation by quintile?</p>
<p>a quintile is 20% or 1/5 of a given sum.</p>
<p>I don’t know what you are referring to by “college matriculation by quintile”, so I can’t help you there. </p>
<p>The first quintile would be the first 20% and the second quintile would be the next 20%, that makes sense.</p>
<p>Avon Old Farms lists thier College Matriculation by Quintile, I take that to mean by the top 20% of the class, the second 20% and so on.</p>
