<p>Graduation rates that low are typical of less selective non-flagship state universities.</p>
<p>The reasons for delayed graduation include:</p>
<ul>
<li>Many students need remedial course work.</li>
<li>Many students fail courses and need to repeat them.</li>
<li>Many students change major late.</li>
<li>Many students attend part time, or take semesters off, to work to earn money for college.  (This can include co-op jobs.)</li>
<li>If the college is inexpensive, students have less incentive to graduate on time.</li>
<li>Courses needed for your major or on-time graduation are overfull or not offered frequently enough for you to take them between completing the prerequisites and graduating on time.</li>
</ul>
<p>Of the above reasons, the last one would be the one of most concern to a student who needs no remedial course work, does not fail courses, and does not change major late. (If you do need remedial course work, fail courses, or change major late, it is not the college’s fault that you graduate late.) You may want to ask on the college-specific forum or people you know at the college about whether this is a problem.</p>
