<p>Collegehelp, there are several things that one must keep in mind. </p>
<p>1) Some universities (mostly private) report superscored SAT averages whereas others (mostly public) do not. There is a difference between the two, with the clear advantage going to schools that report supuerscored averages.</p>
<p>2) As moneydad aptly points points out, some universities, primarily private ones (public universities must, by law, disclose 100% of their students’ admissions data), conveniently leave out segments of their student populations who’s admissions data would raise the overall acceptance rate too much or drop the SAT/ACT figures too much. </p>
<p>3) A significant portion of students at public universities do not prepare as hard for the SAT as students at private elites because they never intended on applying to schools that valued the SAT greatly as private elites do. </p>
<p>4) Finaly, many universities, especially large publics, have many students enrolled in “non-academic” fields such as Agriculture, Nursing etc… Comparing SAT averages at such schools with schools where virtually 100% of students major in a traditional academic field or Engineering is unfair.</p>
<p>In all four cases, public universities are at a disadvantage. For these reasons, comparing overall SAT averages and ranges between universities is not a very reliable method of rating universities. One cannot compare public universities to private universities under any circumstance. And even between private universities, differences should be drawn. If one compartmentalizes schools with similar approaches to admissions and does not attempt to compare across compartments, then comparing universities by SAT averages and ranges would be more reliable. For example, one can compartmentalize schools such as Carnegie Mellon, Cornell, Northwestern and Penn because they all have similar approaches, although Wharton at Penn would distort Penn stats a little. Another compartment would be the large publics elites, such as Cal, Michigan, Texas-Austin, UCLA, UNC, UVa and Wisconsin. Another compartment could be mid-sized privste universities that offer mainly traditional majors as well as Engineering and Business. That would include Brown, Darmouth, Duke, Emory, Georgetown, Harvard, Notre Dame, Stanford, Washington University and Yale.</p>
