<p><a href=“http://heri.ucla.edu/DARCU/CompletingCollege2011.pdf”>http://heri.ucla.edu/DARCU/CompletingCollege2011.pdf</a> page 41 lists student intended majors and their correlations with four, five, and six year graduation rates.</p>
<p>Engineering had the strongest negative correlation with graduation rates; health profession, other technical, fine arts, physical science, and biological science also had negative correlations. Social science, English, history/political science, business, other, and humanities had positive correlations.</p>
<p>The majors with negative correlations with graduation rates tend to have longer prerequisite sequences (so missing/dropping/failing a course is more likely to delay graduation), large volume of requirements (again so that missing/dropping/failing a course is more likely to delay graduation), high workload or time commitment courses (labs, visual art studio, performing art performance) which can reduce the credit load a student can handle, particularly if working part time, and/or a minimum level of rigor that is relatively high (perhaps due to sequenced prerequisites).</p>
