<p>The variance in answers above shows why I don’t use the term ‘tier’. </p>
<p>I try to use the term “Top 10” or "Top 20 or “top 30” depending on the selectivity of the group I am speaking about.</p>
<p>When I say “Top 10”, it is generally the Top 10 National Universities. However, when I say “Top 20”, I personally (I realize others think what they wish to think) include my top 2 LACs – Williams and Amherst. Just personal preferences.</p>
<p>By USNWR rankings on 2 separate lists
The problem exposed here is that USNWR does not have a single list, but separate lists for National Universities, and LACs. They refuse to reduce to a single list and I don’t blame them for this. Yet, for many, especially those who have been dealing with college selectivity for years, the top 2-4 LACs are as desirable as HYP, in that they offere a completely different learning environment, which to some is preferable to HYPSM.</p>
<p>By Selectivity:
I have solved this conceptual problem for myself by disregarding USNWR, and rank ordering Unis and LACs according to admissions selectivity. On this list of mine, positions #11 - #14 are occupied by Pomona College (18%) , Amherst, Williams and Swarthmore (19% each).</p>
<p>By Midpoint 25/75 SAT scores:
Yet another way to attempt to rank the quality of classes/schools.</p>
<p>By Cross Admit battles
This list rank orders both Universities and LACs by admitted student preference data from which the authors have created a rank order of preferences: [SSRN-A</a> Revealed Preference Ranking of U.S. Colleges and Universities by Christopher Avery, Mark Glickman, Caroline Hoxby, Andrew Metrick](<a href=“http://papers.ssrn.com/sol3/papers.cfm?abstract_id=601105#PaperDownload]SSRN-A”>http://papers.ssrn.com/sol3/papers.cfm?abstract_id=601105#PaperDownload)</p>
