<p>Unlike some of the other posters, I believe that 4-year grad rates are extremely important.  Getting in and then through college is expensive.  Who wants to be on the hook financially for more than 8 semesters?  </p>
<p>Of course, one can’t take the data completely at face value as investigations need to be made to understand what’s behind a lower rate of graduation, but I think that this is an element in the college search process that merits greater attention.  </p>
<p>Below is the four-year graduation data from the USNWR online.  Pretty impressive performance by the LAC group which I would interpret to mean that it is less likely that one is going to fall thru the cracks at these colleges.  </p>

<p>I would agree with those posting on retention rates as a potential red flag.  IMO, anything below 85% or maybe even 90% warrants inspection.</p>
